政府科技资助对我国大中型工业企业R&D产出的影响——基于省际面板数据的研究

Effect of Government Science and Technology Subsidies on Large and Medium Industry Enterprise R&D Output ——An Analysis based on the Panel Data of Different Provinces

基于文献研究,构建了一个企业R&D投入产出的计量模型,并利用中国1999-2005年间29个省市(不包括海南、西藏)大中型工业企业的面板数据,对政府科技资助、企业R&D支出、金融机构贷款等对企业R&D产出的影响进行了实证分析。结果表明:从全国总体来看,政府科技资助和企业R&D产出之间没有固定的线性回归关系;进一步对东、中、西部三大经济区域分别研究,发现在中部地区,政府科技资助促进企业R&D产出;在东部和西部地区,政府科技资助对企业R&D产出作用不显著;在东、中和西部的大多省份,企业自身R&D支出明显促进了R&D产出;在东、中、西部,金融机构的贷款对企业R&D产出的影响不显著。

Based on literature review, the paper sets up an econometric model of enterprise R＆D in-out,then by using the panel data of large and medium industry enterprise in 29 provinces and cities（excluding Hainan and Tibet） from 1999 to 2005 which is released by the China Statistical Bureau, gives empirical analysis on the effect of government science and technology subsidies, enterprise R＆D expend, bank loans on enterprise R＆D output. The main empirical findings are following： There is not a fixed linear regression relationship of government science and technology subsidies and enterprise R＆D output in the whole country; in Central of China, government science and technology subsidies have stimulated effect on enterprise R＆D output significantly; in Eastern and Western of China, government science and technology subsidies have not significant effect on enterprise R＆D output; in most of provinces, enterprise R＆D expend have stimulated effect on its R＆D output significantly, but bank loans have not significant effect on enterprise R＆D output.
