政府补贴对军民融合企业创新的影响——基于动态面板模型

为推进军民融合创新发展、优化政府资源配置，研究政府补贴对军民融合企业创新的影响具有现实价值。选取2007-2018年127家军民融合企业样本进行实证研究，纳入地方财政科技支出作为调节变量，以企业寻租变量作为政府补贴的外生工具变量，构建政府补贴对军民融合企业创新投入影响的动态面板模型。使用差分GMM法进行回归估计，结果显示，军民融合企业往期研发投入对当期研发投入有影响，政府补贴对军民融合企业研发投入具有正向影响，地方财政科技支出对政府补贴的正向影响具有放大效应。在实证研究基础上，为促进军民融合协同创新提出政策建议。

An Analysis of the Influence of Government Subsidies on the Innovation of Military-Civil Integration Enterprises:based on the Dynamic Panel Model

In order to deepen military-civilian integration and optimize resource allocation, it is of great practical significance to study the impact of government subsidies on the innovation of military-civilian integration enterprises.This paper selects samples of 127 military-civilian integration enterprises from 2007 to 2018 for empirical research, constructs a dynamic panel model of the impact of government subsidies on innovation input of military-civilian integration enterprises, and includes local financial expenditure on science and technology as a moderating variable.In order to solve the endogeneity problem, the rent-seeking variable of enterprises was constructed as the exogenous instrumental variable of government subsidy, and the difference GMM method was used to estimate it.The regression results show that the previous R&D investment of military-civilian integration enterprises has some influence on the current R&D investment, the government subsidy has a positive influence on the R&D investment of military-civilian integration enterprises, and the local finance science and technology expenditure has a magnifying effect on the positive influence of government subsidy.On the basis of empirical research, this paper puts forward policy suggestions for promoting the collaborative innovation of military-civilian integration.
