Abstract: Based on the panel data of China's industrial sub enterprise ownership, sub region and sub industry from 2001 to 2017, this paper makes a descriptive analysis of the growth and convergence of labor productivity of state-owned enterprises, private enterprises, foreign businessmen, Hong Kong, Macao and Taiwan enterprises in China and sub region by using the indicators of relative labor productivity and coefficient of variation, and uses the two-way fixed effect model to test it. The structure shows that:from the perspective of the whole country, the labor productivity of the three types of enterprises shows significant characteristics of absolute convergence and conditional convergence, but the convergence rate is different. The convergence rate of private enterprises is the fastest, followed by foreign businesses, Hong Kong, Macao and Taiwan enterprises, and that of state-owned enterprises is the slowest. From the regional perspective, the convergence rate of northeast and West China is relatively fast, followed by the central region, while the convergence rate of labor productivity of the three types of enterprise ownership along the coast is the slowest. Therefore, the government should further deepen the reform of state-owned enterprises, encourage the development of non-public economy and improve market competition, which will help to narrow the regional development gap, promote the convergence of ownership structure and promote the convergence of the overall economy.

Key words: ownership structure, labor productivity, region, convergence, difference
