The differential sequence is a concept put forward by professor Fei Xiao-tong to describe the pattern of interpersonal relationship in traditional Chinese society. This paper borrows this concept to analyze the interfirm relations in contemporary China. What is the status of different companies in the market? What non-economic factors have formed this pattern? The traditional market status theory neglects the institutional background of market status. This article has expanded this. The article emphasizes the important role of the state in shaping the pattern of corporate status differences, and the difference of roles in different levels of government-controlled enterprises. Based on the data of listed companies in Shanghai and Shenzhen during 2000-2010, this article constructs interlocking directorate networks, and examines the position of companies with different property rights in the network. The results show that state-owned or controlled companies are more likely to be at the core of the networks, and the higher the administrative level of government-controlled companies, the more likely they are in the core position of the networks. These results all indicate that the market status of Chinese enterprises also presents a pattern of differential sequence, and this pattern is based on property rights.
