在Solow-Barro模型扩展的基础上,构建了国资民资比例的增长模型,揭示了稳态增长路径下国资民资的比例关系.用面板门限回归模型,基于中国工业企业数据库构建出1998-2014年7308家企业的平衡面板数据进行实证分析,考察了不同国资民资比例在门限值前后对于经济(企业)产出总体指标的影响系数的大小,详细分析了影响系数差异的可能原因.实证表明:在经济后发地区,国有经济成分具有引领发展的功能,持续加强后发地区的国资引领和示范作用,就会产生累积效应.我国西部地区可以更加努力吸引东部地区优势不足的国有资本余量,以促进当地经济发展.%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.
