Abstract: Based on the expansion of Solow-Barro model, we build a growth model of the proportion of state-owned capital and private capital, and reveal the proportion relationship between state-owned assets and private capital under the path of steady growth. Based on the panel threshold regression model, an empirical analysis of the balance panel data of 7308 enterprises in 1998-2014 years is constructed based on the Chinese industrial enterprise database. The impact coefficient of the proportion of national capital and private capital on the overall economic (enterprise) output index before and after the threshold value is investigated. The difference of the influence coefficient is analyzed in detail. It can be the reason. The empirical evidence shows that the state-owned economic components have the function of leading the development in the economic post area, and the cumulative effect will be produced by continuously strengthening the leading and demonstration role of the state capital in the rear area. The western region of China can make greater efforts to attract the surplus of state-owned capital in the eastern part, so as to promote the development ofeconomy.

Key words: state-owned assets, industrial transfer, mixed ownership
