摘要
本文在规模报酬可变的条件下,构建了网络DEA模型,测算了2002-2008年中国大中型工业企业的技术创新效率,在此基础上探讨了环境规制对技术创新效率的影响机理,并以中国三大经济区域面板数据进行实证检验。研究结果表明:环境规制强度与技术创新效率在东部地区符合"U"型关系,在西部地区呈现倒"U"型关系,在中部地区尚未形成统计检验上显著的"U"型关系;垂直专业化水平和市场化程度对东部地区技术创新效率具有显著的促进作用,而在中西部地区并没有对创新效率带来积极影响;人力资本存量整体对技术创新效率的正向效应不明显。
This paper measures the efficiency of technology innovation of large and medium industrial enterprises in China from 2002 to 2008 by constructing a network DEA model under the assumption of variable returns to scale.Then we try to identify and estimate the mechanism of effects of environmental regulation on the efficiency of technology innovation by using panel data of the Three Major Economic Regions.The results show that:(1) between the intensity of environmental regulation and enterprise's efficiency of technology innovation there is a U-type relationship in eastern regions and a inverse-U-shaped pattern in western regions,but in central regions,the intensity of environmental regulation and enterprise's efficiency of technology innovation haven't formed a Utype relationship in statistical significance;(2)both vertical specialization and market mechanism degree have promoted the efficiency of technology innovation significantly in eastern regions,but in central and western regions they haven't brought some positive effect on the efficiency of technology innovation;(3)human capital stock has little positive effect on the efficiency improvement.
