In TPP Chapter 17“State-owned Enterprises and Designed Monopolies”, there are a series of obligation regulations which are of high level standard, regarding state-owned enterprises (SOEs) and aiming at keeping a level-playing field in markets by regulating the behavior of TPP parties and their SOEs. Article 17.1 stipulates the definition of the objects that are restricted by the TPP competitive neutrality. Once China joins the Agreements requiring TPP competitive neutrality, there will definitely be some challenges that arise from its acceptance. However, the premise is that lots of enterprises are defined as SOEs under the TPP clause. In this paper, the conformity of the Chinese A-share listed companies and the defining standards of state-owned enterprises were investigated through analysis of recent data, in order to explore how many Chinese enterprises the TPP competitive neutrality will restrict. The study shows that the independence of judgment criteria of right to eguity, vote and appointment is not fully embodied in TPP, and fewer Chinese listed companies will conform to such criteria.
