This paper bases its analysis on the Bernard Conference known as the beginning of the famous feminists’ sex war in 1980s. Surrounding the themes on pornography, lesbian TP roles and S/M issue, the debates under the “pleasure and danger” theoretical framework divided US feminists into two strands: sex radical feminists and anti-porn feminists who are also known as dominance feminism. The significance and influence of sex war has been lasted for more than 30 years, and dominance feminists are still active in sexual politics on issues such as sexual harassment within and beyond US context. The tracing back to 80s sex war and following feminists’ debates on sex issues in US is expected to give insights to better understand what are happening in current mainland China. Thinking sex in Chinese contexts and proposing efforts toward alternative sexuality discourses and statements rooted in local historical, cultural and social worlds are crucial yet challenging.

社会科学自其诞生以来在思维逻辑和研究方法上一直受到自然科学的思维逻辑和方法的影响。本文指出社会科学和自然科学在逻辑和方法上八个方面的重要区别，并提出这些区别的本源就是人的特性， 即人是又有本能，又讲策略，又会运用意识形态和价值来论证自己行为正确性的动物。 本文强调对社会科学与自然科学这些区别的忽视是西方社会科学长期以来徘徊不前、步入误区的根本原因。

自罗伯特·金·默顿提出“中层理论”以来，它业已成为社科研究中最重要的方法论概念之一。在为社会科学发展做出巨大贡献的同时，它也遭遇到很多批评。系统回顾中层理论的历史、价值和局限性，并从社会科学哲学的角度予以评判，有助于我们超越目前常见的从经验主义和实证主义立场对此概念所做的解读和倡导，更深入的理解宏大理论、中层理论与经验研究三者之间的关系，进而为当代中国的社会学研究提供有益反思。

This article is a response to Professor Li Lianjiang’s criticism of my earlier article entitled “Differences between the Natural and Social Sciences and Their Implications for Social Science Research.” It discusses the relationship between the concept of “rightful resistance” developed by Professor Li and the concept of “everyday resistance” proposed by James Scott, and explains why everyday resistance is a successful concept, but rightful resistance is not. More generally, I argue that the value of an interpretative concept lies in its capacity to deconstruct rather than to construct. Put differently, a successful interpretive concept should highlight previously neglected aspects of social life, rather than delineate the pattern of activities of a category of people that has a very complicated nature.

The paper reviews the studies on Chinese middle class since the 21st century. The author points out that the basic issues of both Western and domestic studies on the middle class come from Marx’s middle class theory, including class structure, class formation and social function. However, the existing studies have many controversies on these three aspects due to different theoretical background and empirical materials. And the author stresses that the researchers in the future should pay more attention to the development of the middle class during past decades as well as comparative study of these three aspects based on a unified class framework and rich survey data.

As a unique landscape of the vigorous development of China’s network society in recent years, the phenomenon of internet celebrity popularity has not only witnessed the dramatic changes in the fate of individuals, but also embodied a powerful economic and social forces. Based on Castell’s “network society” theory, taking the perspective of tech-social mutually construction, this paper makes a historical comparative study on the characteristics, logic mechanism and consequence of the internet celebrity popularity. The article finds that the social media and users population structure are the important factors in shaping the expression, group characteristics and basic attributes that affect the internet celebrity popularity. The fact that the social structure of social interaction is generated by the phased network society through three different types of logical mechanism: public square effect of virtual space, the social interaction mode by online community and the capital market intervention. The consequence of the popularity of the internet celebrity has undergone a transitional evolution from the cultural and social fields to the economic fields, and turned out the Wanghong economy model in process of Internet economy flourishing. The popularity of the internet celebrity provides a vivid sample for understanding the formation mechanism and development of China's network society.

Gender role attitudes are about how a person identifies oneself with regard to rights and roles linked to gender in family and market, and also reflect the gender equality in society from another dimension. Using data from “2010 Chinese General Social Survey”(CGSS2010), we estimated associations of socioeconomic status (SES), gender inequality and gender role attitudes. Results suggest that gender role attitudes were significantly related to people’s social positions: The higher were people’s SES, the more liberal were their gender role attitudes. The associations of SES and gender role attitudes changed among women and men: the positive effect of the socioeconomic status on women’s gender role attitudes was stronger. Women with higher SES demonstrated greater modern trends in gender role attitudes than did men with the similar social positions. The effect of gender inequality among couples on change in gender role attitudes were also different between women and men. Women’s gender role attitudes were positively associated to their relative education and earnings, but men’s attitudes are not affected by their relative resource among couples: the more relative education women have, the more they expressed equal gender role attitudes; the more relative earnings women have, the more they hold nontraditional gender role attitudes, however, when women’s relative earnings rised at some point, their gender role attitudes reversed to be more traditional.

学界对当代中国社会是否已经“阶层固化”存在分歧，亦缺乏明晰的科学检验方法。本文考察公众对自身阶层流动情况的感知和对“阶层固化”话语关注之间的关联，以对这一命题进行实证检验。我们认为，如果“阶层固化”渐已成为社会现实，那么在宏观层面，过低的流动率会使得公众总体的自我流动感知恶化，触发人们对“阶层固化”的关注：流动感知越向下，固化关注度就越高。反之，如果“阶层固化”并非现实而只是一种预警，社会流动率并没有降低到危险点，那么公众对“阶层固化”的关注，和自身的流动感知就不会存在关联。就此，我们构建起“阶层固化”话语列表，利用其在百度的被检索热度来生成各省历年“阶层固化”关注度指数，并将其与中国综合社会调查（2008-2012）的流动感知数据及统计年鉴资料相匹配。基于省域面板数据的多模型分析揭示了“无关的流动感知”这一重要现象：当代中国公众基于自身经历的代内流动感知和代际流动感知，与“阶层固化”关注度均没有负向的统计关联。这一发现意味着“阶层固化”在当代中国更多地是一种预警而非社会现实。

With the widespread penetration of mobile Internet, online social mentality is not only an indispensable part of social mentality study, but also an important window to the understanding of the Chinese cyber-society. Based on a systematic review of the extant literature, this article contends that online social mentality manifests four key features of community specificity, extremity, fluidity and network-embeddedness, and proposes a theoretical conception of online social mentality as a relational, locally inter-subjective and relatively fluid socio-cultural phenomenon. This conception indicates that empirical studies should be conducted inductively, with typology analysis and discourse analysis being the most useful analytical approaches, and that community-based social mentalities, the polarization of social mentality and the emerging process of social mentality are three significant topics in online social mentality studies.

The relationship between the state and society is the basic proposition of social science, which is also a controversial topic area. On the basis of reflection and dialogue to the relation between state and society, Joel S. Migdal is aware of the "reductionism" tendency in Weber's view of State, and then he constructs a new state definition, puts forward the unique "view of State" on the basis of empirical research. Meanwhile, combining with the perspective of procedural, he constructs the path "state in society" from the perspective of methodology, makes a new dynamic, procedural and constructive interpretation of the relation between state and society, which avoids the limitations of one way understanding from the old “state-centered” and “society-centered” theory, deepens the understanding of complex social reality, and opens up a new era of study on the relationship between the state and society, which also has the vital significance in methodology.

Abstract: The emergence of “Orders of Simulacra” indicated that Baudrillard began to turn to pessimism. This article focuses on “Orders of Simulacra” text analysis, which is on the basis of existing debate about his pessimism turning, summarizing the core idea of “Orders of Simulacra” in the different link, such as criticizing, the orienting of problem, logical reasoning and the path to save. From the perspective of the premise, this article argue that, There is a logic jumping between criticism and solution to the simulation society in Baudrillard’s theory. He criticizes actuality with the “truth”, but solves the problem with the “real”. It avoids falling into the trap of “Orders of Simulacra” designed by himself, but overlooks the significance of mundane ethics as premise, because of stucking in the binary frame of “mundane- sacred”. It Finally makes “Orders of Simulacra” descend to a corner of DECONSTRUCTION of the 20th century, bowing to absurd metaphysics and pessimism. Keywords: orders of simulacra; symbolic exchange; mundane ethics; simulation

Based on a thorough literature review, this paper outlines the major problematics and approaches of carework study from western sociological and anthropological perspectives. It pays special attention to the booming care jobs since the 1980s, shaped by the structural forces of economic globalization and the neoliberal state. This paper argues that three research topics can be summarized, including‘the gendered framework of carework’,‘the stratified division of carework’, and‘carework as intimate labor across the realms of market and intimacy’. This paper further explores the significance as well as some potential research projects for studying the cases of China.

It is necessary to go back to the original context of Cha-xu-ge-ju and Xiang-tu-zhong-guo to understand the classical concept “Cha-xu-ge-ju” put forward by Fei Xiaotong. On one hand, to understand “selfishness” (Si), the relationship of Cha-Xu-ge-ju and we-relation-based egocentrism (Zi-wo-zhu-yi) should be concerned with. Cha-Xu-ge-ju” is the fundamental social structure of Chinese society, behind which is the thinking structure, we-relation-based egocentrism. We can discuss about the main aspects of we-relation-based egocentrism clearly by contrast with individualism. On the other hand, we should put Cha-Xu-ge-ju into the whole fundamental rural social order, to understand the boundary of we-relation-based egocentrism. In traditional society of China, the etiquettes and customs had controlled the boundary of we-relation-based egocentrism. However, the traditional etiquettes and customs based on Confucian ethics had been weakening, which led to a problem that the constraints on we-relation-based egocentrism are not enough. How to maintain the fundamental social order becomes a serious problem. Under the background of social construction, it is meaningful to discuss we-relation-based egocentrism and its influences on social order.

Big data studies in sociology have been treated as a new trend or promising direction mainly in the statistic or quantitative areas. However, our digital lives embedded with information technology generate a“new sociality”, the existence and practice of the subject experienced a radical change. With some new“digital troubles”, the subject has been offered more opportunities and increased flexibility. Theoretical studies are also required urgently in the era of big data. Sociological theories should understand and interpret our digital lives. Moreover, practicing sociological imagination in the contemporary context of datafication of everything, an updated imagination is required to interpret or “unlock”the digital lives of our time.

Abstract: In the international comparison study of the social mobility, Erikson and Goldthorpe’s class categories (EGP) is commonly used in the social class classification. How to convert Chinese standard occupational classification directly to social class classification standard of international comparison, which is a very complicated question. The recent domestic research has no clear discussion about it. To deal with it, this study based on combing EGP pattern carefully and combined the method of Ganzeboom and Treiman, Puts forward the specific conversion principle and the conversion program (two forms of SPSS and STATA). This work not only provides an important method support for later researchers, but also benefit to grasp the position of Chinese social mobility model in the international world.

本文对网络社会中的“全景敞视”予以分析。互联网技术全面提升了监视的程度，在网络社会中，监视是可见的但又无法确知的，通过自动化、非个人化监视，进一步落实了监视权力的网状分布，开展全方位的监控，并构建了永恒的档案记录，因而一定程度上互联网实现了“完美”的“全景敞视”。在强化、升级的同时，互联网中的“全景敞视”也发生变异，体现为被监视的个人不再相互隔离，监视是扁平化的，检查和档案分离。此外，互联网中的监视方向出现分化，不仅有国家对个人的监视，还有个人对国家的监视以及个人之间的相互监视。不同的监视方向有不同的数据基础，不可等而视之。随着社会生活的网络化，互联网不仅能监视虚拟网络社会，还能监视实在网络社会，而网民在这一潮流中难以脱离，只能谨言慎行。网络社会是否会基于“完美”的“全景敞视”而开展规训，这有待进一步的研究。

A paradox of Chinese homosexuals’ pursue for intimacies arises from the emerging homonormativity in contemporary China: on one hand, the non-marital sexual behaviors have been rejected by the mainstream social norms; on the other, same sex marriage is not an available option for them. Based on the analysis of Chinese same sex marriage, this paper critically explore the public/private distinction theory. Firstly, chaxu geju as a conceptual framework has been introduced to highlight the scalability and relativity of the boundary between the public and the private in Chinese society, in order to critically analyze the role of state and the myths of the family in the discussions of same sex marriage. Subsequently, based on the argument of the feminist scholars such as Judith Butler, Nancy Tuana, etc., the “person” situated in specific power relations in the slogan “personal is political” has been replaced by a more general “person”, following which the epistemological analysis of the consequences of knowledge/ignorance behind the attitudes of ordinary people towards same sex marriage has been made. This is a travel of the public/private distinction theory across different worlds: from the western to China, from the specific gendered power relations to the more general Chinese society. There are different selves with different attributes of the theory in different worlds, based on which the new possibilities of reading, using, revising, and developing theory have been opened up

The concept of “sense of security” have dual attributes of psychology and sociology. In social psychology,the current situation and characteristics of public sense of security in our country were analyzed using the massive data from Internet survey. Then we discussed the reasons for the lack of public sense of security from the perspective of social transformation, pointing out that development and reform had double-edged sword effects on public sense of security. At last, we put forward our countermeasures and suggestions on how to promote the public sense of security.

产生于20世纪90年代末的话语机会结构理论，是基于对社会运动的政治机会结构理论和框架化理论的批判和整合而形成的一种新理论，重在强调话语框架取得成功的社会文化因素。近年来，话语机会结构理论在西方学者的经验研究中得到了广泛运用，在国内却较少受到研究者的关注。本文对话语机会结构理论的衍生历程、研究现状和发展趋势等问题进行系统梳理，以拓展我们对社会运动理论的认识。

在与列斐伏尔、福柯、詹明信、吉登斯等空间理论家进行对话的基础上，苏贾的后现代空间理论重申了批判社会理论中的空间。社会、权力、后现代性和时间等既是后现代空间理论的分析维度，也是空间理论的经验实践。虽然后现代空间理论还存在一定的局限性，但这并不影响批判社会理论的空间构型的价值和意义。当前空间理论正朝着一个拥有多个分析维度、具有鲜明反思性和批判性的综合理论体系的方向而建构，并试图发展出一个经验型和阐释性意义上的批判社会理论体系。

With the spread of blockchain technology and the soaring price of bitcoin in recent years, many countries, including China, have seen a craze of cryptocurrencies in 2017. However, despite the rush of investors, a large number of cryptocurrencies are just shell projects or outright scams under the banner of blockchain. The white paper is a project introduction written by cryptocurrency issuers to attract investors. This paper collects and analyzes all the white papers written in Chinese currently available in the financial market, reveals the seven main narratives of the cryptocurrency industry and makes a portrait of ideas for the people involved in. We argue that the cryptocurrency is a self-protective invention when society is facing the systemic crisis of financial capitalism, although taking a good faith to resist the financial culture, it ultimately becomes the carrier of financial culture reproduction, which means the financial capitalism has achieved the dynamic generation as a new historical form.

This article first summarizes and then criticizes five different understandings of time and temporalities in the Western world. It then proceeds to propose five other understandings of time and temporalities: the cumulative developmental time derived from the natures of the economic and military power, the pluralistic time arising from the natures of ideological power, the increasingly prevailing political time due to the natures of the political power, the cyclic Daoist time, and the compound time of the empirical world (compound of the cumulative developmental time, pluralistic time, prevailing political time, and Daoist cyclic time). This article discusses the empirical relevance of my five understandings of time and tries to establish two arguments: First, the essence of historical sociology is not to study past happenings, but to organically combine the chronology/time-based narrative of history and structure/mechanism-based narrative of sociology. Second, establishing a Chinese ontology of time is a way to develop social sciences with Chinese characteristics.

Although the social nature of space has been discussed widely, its sociological nature hasn't yet. There is no systematic answer for how can we take space as a sociological perspective to explain social problems. Therefore, the study tries to reveal the orientations and limitations of spatial interpretation in sociology. It suggests that spatial perspective has four dimensions in Sociological Interpretation.(a)For social structure，the occupancy state of space constitutes the motive force of social stratum differentiation.(b)For social change, the production of space affects the direction and speed of social change.(c)For social control, the localization of space has become the main skill of power operation.(d)For social action, The claim of space constitutes the important logic of Urban social movement. Further，the study reveals two characteristics of the Spatial Interpretation: situationality and compound. Then, after affirming the advantages of spatial perspective basing these two characteristics, its limitations in study came into question.

For humans, all of cognitions and emotions take place in the brain. The gaps of academic achievement between social classes are closely related to the neuron activities in the brain. The paper briefly reviews how the social economic status shapes the development of the brain. Furthermore, based on existed scientific evidence, the paper claim that the reason why poverty does harm to the brain is not for the poverty itself, but for the stress caused by poverty. Brain research reveals micro mechanisms for social class leading to gaps of academic achievement. The paper summarizes intervention strategies based on neurosciences, and presents an alternative approach to block the inter-generational reproduction of poverty. In the last part, the paper gives an extended discussion about the integration of social sciences and natural sciences as the most effective research strategy.

This paper uses two indicators, whether going on business trips and the intensity of going out on business, as proxy for laborers’ job market involvement to empirically explore the gender differences in travelling on business and its resulting income effects on gender-earning differentials. Based on 2014 Social Networks and Job Search Survey data set, findings show that the rate at which men participate on business trips is much higher than that of the women’s, by approximately 1.8 times. Compared with laborers who do not go out on bussiness, those who have short stay and long stay on business trip respectively earn 19% and 35% higher. A series of statistical models, including Heterogeneous Treatment Effect Models have proved the robustness of these findings. On balance, gender differences in two indicators of business trips can explain 19% of the gender-earning differentials, and contribute to 88% of the total. Moreover, it is found that two indicators of business trips have indeed affected laborers’ investments in human capital, social capital, and their promotion within the organizations. It is speculated that gender-earning differentials originates from cultural bias, which is rooted in patriarchy, rather than from employers’ discrimination.

This paper attempts to sort out the development clues of China's labor sociology in the past 30 years. This paper shows that: the last decade of the 20th century was the first period of the development of labor sociology. At this time, Chinese sociology began to explore the labor problem, but there was a suspicion of misuse of theory. The first decade of the 21st century is the second stage of development. Sociology begins to study labor under the theoretical framework of labor sociology. This paper mainly takes the field study of Tsinghua labor sociology as an example to illustrate the characteristics of this period. The second decade of the 21st century is the third period of development. The basic characteristics of this stage are to explore new labor groups and form a new vision of research. The evolution of the three periods reflects the basic changes and internal logic of Chinese labor sociology.

本文通过梳理义乌模式中早期的一个焦点现象即鸡毛换糖，呈现了义乌农民经商过程中商业行动的起点、过程特质及以此为基础形成的文化积淀。由于农民经商的“本钱小”选择了小本买卖“鸡毛换糖”；由于进入经营的门槛低、经营者众多可替代性强，加上农民经商的“家庭副业”的定位，形成“薄利”经营；为了规模化、持续经营而追求“回头客”以实现“多销”。这些特质逐步凝炼成一种“复数行动”的实践习惯和区域文化。复数行动让义乌经营者积累了经济资本、人力资本、社会资本等。现今探讨复数行动在调整商业经营心态、建立常久的、稳定的、可持续的商业互动关系、反对短期行为等方面具有重要的伦理意义。, 本文通过梳理义乌模式中早期的一个焦点现象即鸡毛换糖，呈现了义乌农民经商过程中商业行动的起点、过程特质及以此为基础形成的文化积淀。由于农民经商的“本钱小”选择了小本买卖“鸡毛换糖”；由于进入经营的门槛低、经营者众多可替代性强，加上农民经商的“家庭副业”的定位，形成“薄利”经营；为了规模化、持续经营而追求“回头客”以实现“多销”。这些特质逐步凝炼成一种“复数行动”的实践习惯和区域文化。复数行动让义乌经营者积累了经济资本、人力资本、社会资本等。现今探讨复数行动在调整商业经营心态、建立常久的、稳定的、可持续的商业互动关系、反对短期行为等方面具有重要的伦理意义。, 本文通过梳理义乌模式中早期的一个焦点现象即鸡毛换糖，呈现了义乌农民经商过程中商业行动的起点、过程特质及以此为基础形成的文化积淀。由于农民经商的“本钱小”选择了小本买卖“鸡毛换糖”；由于进入经营的门槛低、经营者众多可替代性强，加上农民经商的“家庭副业”的定位，形成“薄利”经营；为了规模化、持续经营而追求“回头客”以实现“多销”。这些特质逐步凝炼成一种“复数行动”的实践习惯和区域文化。复数行动让义乌经营者积累了经济资本、人力资本、社会资本等。现今探讨复数行动在调整商业经营心态、建立常久的、稳定的、可持续的商业互动关系、反对短期行为等方面具有重要的伦理意义。

“国家”与“社会”可以说是在相互划清边界的过程中彼此赋予发展动力而产生与形成的。政治国家与市民社会并存乃是现代国家的一个基本特征；国家与社会的互动关系则形塑社会结构、影响社会秩序。作为社会科学研究的经典分析框架，“国家与社会”范式在被引入当代中国研究领域后，迅速成为城市基层研究的主流，并产生了大量的研究成果。这些研究有助于我们认识当代中国社会政治秩序的整合路径；但也日益陷入一种同质生产、难以取得理论突破的境地。为克服国家与社会框架的内在张力，我们需要在研究中反思城市基层的“社会”如何实体化操作、其多层复合属性以及内部的多样性和不一致性，“国家”的实体化操作问题及其角色的多维性，以及城市基层“国家”与“社会”的联结机制。在此基础上，还需要进一步反思“国家与社会”范式作为特定的“知识生产”成果所具有的政治、文化和意识形态等知识社会学属性。

China has witnessed a rising number of protests in recent years. Different from conventional agricultural protests, these instances of collective action have been initiated by the urban property-owning middle class. Through field work and in-depth interviews, this study compares two related protests, one by farmers and the other by the middle class, and investigates the dynamics among these two groups, the media and the government. We examine the difference of these two protests in action repertoire, organizational mobilization, movement resources, and media discourses. We argue that these two cases not only reflect the distinction between conventional and modern collective action in China, but also illustrate the interactive mechanisms between these two types of protests. Compared with farmers, weapons of the middle class are more diversified, depoliticized and innovative. The middle class are more capable of constructing plural media discourses and maintaining media’s attention. During the process, the interests of farmers and of middle class were intertwined. The middle class successfully borrowed moral resource from the farmers, which led to differences in their respective media discourses, causing the two protests to end with different results.

Formal theories have been broadly used in social science. Especially, the whole Micro-economics is a typical application, while in sociology are quite few. Fortunately, Mark Grannovetter's threshold models seem regarded as a paragon. Owing to the scarcity of formal theories in Sociology, We will focus on the establishment and extension of threshold models in order to explore the approaches to formal sociology. First, we will illustrate the formalization and mathematical analysis of the simple threshold model, and explain the logic of theory accumulations in two complex ones; secondly, the comparison between the development of Micro-economics and threshold models will help us generalize the special characteristics of formal theories in Sociology.

“合法性”对组织的生存和发展至关重要。现有研究大多关注的是国家政权或社会组织的合法性问题，缺乏对社区自治组织合法性的系统分析。本文对居民委员会和业主委员会在法律、政治、行政和社会不同领域的合法性水平及其基础进行全面比较，指出两种社区自治组织的合法性存在着不对称的特点：一方面，居委会和业委会在自身不同类型的合法性水平上差别很大，且存在着内部张力；另一方面，两者之间的合法性形成不对称格局，一方合法性强的类型正是另一方合法性弱的类型。这种不对称的合法性反映了国家和社会在效用和价值观上对两种社区自治组织的认知和期待存在着深刻差别。居委会和业委会也因此面临着不同的合法性危机或困境。

The systems theory does not have a third phase in terms of inclusion/exclusion. Systems theory does not deny the fact there are “de-differentiation” and “impossibility for communication” in reality. Luhmann’s systems theory’s basic theoretic underpinnings have already been able to explain inclusion and exclusion. But, the idea of inclusion and exclusion are not redundant. They are the “individualization” dimension of systems theory, and they are also the answer to the fundamental issue in social theory “how society is possible”. Those who agreed that there is a third phase in systems theory did not notice the aforementioned theoretical underpinnings, and they also ignored the first and second order observations are interchangeable in inclusion and exclusion. Literatures in systems theory did not point to those errors. The proposition of “third phase” in systems theory hampered the development of systems theory and its application.

Female has been marginalized regarding the perspective of technological development, whereas modern ICTs has paid less attention in that either. Extending from the theory of social boundary, this article aims to explore how female programmers form their identities and gender boundaries during the work practices. Through a combined method of ethnographic fieldwork and interview, it explains how female programmers construct their gender boundaries through social processes of enhancement and minimization. It indicates that the construction of gender boundaries is not fixed, clear or unified as we have assumed, rather, it is a flexible and shifting process undergoing in the communication practices of female programmers.

笔者认为科斯和弗里德曼两人对“假设真实性”问题认识的差异其实并没有那么大，甚至比他们自己认为的更小。弗里德曼对话的主要对象是列斯特，重点在于作为公理的基础假设是否应该是真实的。科斯对话的对象是“黑板经济学”，交易费用是科斯解释企业存在的自变量。科斯讲的假设是关于自变量的假设，不是基础假设或关于无关变量的假设。所以科斯更强调关于自变量的假设应该是真实的，而弗里德曼则更强调关于基础假设以及无关变量的假设不一定必须是真实的。厘清上述问题有助于我们更好地讨论“理性人”假设在社会学中的适用性问题。

Based on the analysis of the “human nature”, Zhao Ding-xin discussed the differences between natural and social sciences in his article, and interpreted “the predicament of social sciences”. But Zhao’s analysis mainly relies on the epistemology of the natural science, and may miss the development of the paradigm of social sciences. This article points out that the concept of time of theoretical sociology is not only the very point to clarify Zhao’s epistemology, but also the core to construct a paradigm of the social sciences.

Rawls showed some restricted conditions in the "original position" that is need to demonstrate the principle of justice. He tried to justify the national welfare policy by the difference principle. Rawls's "original position" and his method of demonstration are valuable, but the theory of philosophy is faultiness which the difference principle based on. He denied the right of individuals to their natural talents. The individual's natural ability is seen as a common asset by him. In fact, in the material wealth of human society, only natural resources are the common asset. The principle of everybody’s equal right for the natural resources will be selected in "the original state ". The principle not only can make the national welfare policies have a more solid foundation, also can make it easy.

The gender gap in career promotion is not only an important indicator of labor market inequality, but also an important mechanism of inequality reproduction. Domestic studies have neglected the impact of family and husband on the rise of women's professional status. This paper uses the CFPS "China Family Tracking Survey" data in 2010 and 2014 and match the couple data to explore how husbands influence the wives’ professional status. This paper synthesizes the theory of gender power and verifies the theory of "husband inhibition" and "husband support". The study found that factors such as husband's income, female's emotional dependence, housework and family care time had a negative impact on the rise of women's professional status, and the "husband inhibition theory" was verified. Social network can promote the rise of women's professional status. However, the results show that the intermediary effect of social network on husband's income is not significant. The theory of husband's support has not been confirmed.

In 1947, Fei Xiaotong proposed the term of "Diversity-orderly Structure" in his famous book Xiangtu Zhongguo (Native Soil China). This term has been kept using in social science research and became a classical concept in China studies. How does a term become generally used by social scientists? This depends on very good sense of researchers and also depends on sound naming method. This paper focuses on the methodology of naming and its relationship with the originality of research. Through analyzing this term in the book, the author will also discuss the method used by the biologists, especially Darwin.

By drawing data from the 2008 China Suboptimal Health Survey and estimating multinomial logit models, this study examines the relationship between socio-economic status and obesity. The main results show that, firstly, in general, urban males and rural females are the most vulnerable to obesity nowadays in China. The relationship between income and obesity is nonlinear, and the highest chance of being obese occurs to people with middle income instead of the highest income group. Yet a much more positive connection between income and obesity is observed among males and rural residents, to whom the highest income group is more likely to be obese, while this relationship is statistically insignificant among females and urban residents. Moreover, the association between education and obesity is in contradictory direction between men and women, with the former being positive and the latter being negative. These findings are helpful for us to better understand the social mechanisms that drive the occurrence of obesity in China.
