摘　　要：政府为推进本国技术创新而发生的财政支出对企业创新行为具有重要影响。本文基于这一事实,构建包含企业创新行为差异的简单动态随机一般均衡模型,分析得出:由于技术创新密度不同,企业可分为技术创新型企业和技术稳定型企业。技术创新型企业提高技术研发投资比重,虽然不一定能迅速实现经济产出的提高,却可以推动本国经济从传统的粗放投资型转化为高质量的技术创新型。在一定时期内,政府技术创新支出是企业技术创新支出增加的主要外在推动力,对企业创新具有显著的助推作用,对宏观经济及发展具有重要的正向作用,但具体效果还取决于企业创新投入情况。相比较而言,当创新企业技术投入率达到一定界值时,政府技术创新支出的效率会更高。这些结论对完善创新政策、改进市场规则、进一步提升创新效率具有一定的政策含义。In recent years,developing countries convenience in using international technology spillovers has gradually disappeared,and independent technological innovation has become the main approach.To solve the problem of technological innovation,developed countries have generally adopted measures such as government subsidies and tax cuts,but there have been many disputes over the measures.The most important dispute has centered on whether a developing country s economic system,depending on the push of a construction investment,can be rapidly transformed into an economic system dominated by science and technology innovation by significantly improving the government s technological innovation expenditure while maintaining the economic growth rate.This has important theoretical and policy-related implications for the effects of China s government technology innovation expenditures on its economy.To study the role of government technology innovation expenditures on technological progress and other economic effects,based on analysis of the difference in China s industry technology input rate,we confirm the significant differences in technological innovation investment behaviors across different industries,test the effect of government funding support on different firms technology innovation investments through the generalized method of moments,construct a simple dynamic stochastic general equilibrium model that includes the innovative heterogeneous firms,and simulate the impact of government technology innovation expenditures on technological progress and output.We obtain four results.First,according to the difference in China s industry technology input rates,firms can be divided into two categories:technologically innovative firms and technologically stable firms.A firm s profit is the most important internal source of the increase in firm innovation investment,and the sales profit rate plays an important role in guaranteeing and promoting investment in firms technological innovation.Residents carry out investment structur
