政府补贴对企业出口产品质量的影响研究

Research on Impact of Government Subsidies on Quality of Enterprise Export Products

为促进我国出口贸易结构优化升级,运用大样本企业微观数据和Heckman样本选择模型实证分析政府研发补贴对我国企业出口产品质量的影响。研究结果表明:政府补贴显著提升了企业出口倾向和出口产品质量,且所得结论在逐步回归检验后依然成立;通过分样本比较分析可发现政府补贴的激励效应因企业类型不同而存在差异,政府补贴对民营、资本密集及一般贸易企业出口产品质量的影响显著大于国有、劳动密集及加工贸易企业。由此可知,我国政府研发补贴政策措施是必要且有成效的,因而政府应继续加大补贴投入的力度,扩大补贴投入的广度,同时应合理选择补贴对象并完善补贴制度,以充分发挥政府补贴的激励作用。

In order to promote optimization and upgrading of Chinese export trade structure,based on the large sample of firm micro data,this paper empirically analyzes the impact of government RD subsidies on the export product quality of Chinese firms with the Heckman sample selection model.The result shows that government subsidies significantly increase enterprise export tendency and the export product quality,and this conclusion still holds after the stepwise regression test.Comparative analysis of samples shows that the incentive effect of government subsidies varies distinctly with the firm types,and the impacts on private,capital intensive and general trade firms are more significant than on state,labor intensive and processing trade firms.Therefore,our government subsidy policy is necessary and effective,and the government should continue to increase the intensity and scope of subsidies as well as reasonably choose the subsidy objects and perfect the subsidy system,in order to give full play to the incentive role of government subsidies.
