创新驱动、政府作用与民营经济发展——基于全国30个省市数据的门限效应分析

Innovation-driven,Government Role and the Development of the Private Economy: a Threshold Effect Analysis Based on China’s 30 Provinces Data

创新是推动民营经济发展的重要因素。本文基于我国2002-2016年省级面板数据,以政府作用为门限变量,构建面板数据门限模型,检验我国创新驱动与民营经济发展之间的非线性关系。研究结果表明:创新驱动与民营经济发展之间存在政府作用双重门限效应。随着政府作用的扩大,创新驱动对民营经济发展的正向影响先增强后减弱。上述发现表明,政府作用是影响我国创新驱动与民营经济发展关系的一个重要因素。因此,在创新驱动民营经济发展的过程中,应当充分考虑政府作用水平的适当调整,适应创新驱动发展要求,跟随创新产业化的不同发展阶段、针对不同区域、不同行业、不同民营企业规模调整政策组合结构,转变政府政策边界,避免政府“作用过度”和“作用不足”,确保企业创新主体地位;强化政策执行跟踪反馈机制,提高民营企业信息化服务水平,提高政策的实效性与时效性。

Innovation is an important factor to promote the development of private economy.Based on the China’s provincial panel data(2002-2016),the panel data threshold model is constructed with the government role as the threshold variable to test the nonlinear relationship between innovation-driven and the development of private economy in China.According to the results,there is a double threshold effect between innovation-driven and the development of private economy.With the expansion of the government role,the positive impact of innovation-driven on the development of private economy is first enhanced and then weakened.According to the above findings,the government role is an important factor between innovation-driven and private economy in China.Therefore,in the process of innovation driving the development of private economy,the appropriate adjustment of the government role should be fully considered.Adapting to the demands of innovation-driven development,it is necessary to adjust the structure of policy mix and change the boundary of government policies according to the different development stages of innovation industrialization,different regions,different industries and different private enterprises.The government should avoid“excessive role”and“insufficient role”,and ensure the role of enterprises as players of innovation.It is necessary to strengthen the tracking and feedback mechanism of policy implementation,improve the informatization service level of private enterprises,and improve the effectiveness and timeliness of policies.
