摘要
首先通过引入经济距离空间权重矩阵,计算空间溢出效应指标,构建企业研发投入的空间杜宾模型;其次,基于我国31个省、市和自治区大中型工业企业2009-2015年的数据,实证分析企业研发投入的空间依赖性。分析结果表明,企业研发投入确实存在空间依赖性,企业研发投入、政府研发补贴和企业净利润的空间滞后项对企业研发投入具有正向影响,即其他地区的经济距离加权平均企业研发投入、政府研发补贴和企业净利润会促进本地区企业研发投入的增加。
This paper firstly calculates the spatial spillover effect by introducing the spatial weight matrix of economic distance,and constructs a spatial Durbin model for enterprise R&D investment;then this paper presents an empirical analysis on the spatial dependence of enterprise R&D investment based on the data of large and medium-sized industry enterprises in 31 provinces,municipalities and autonomous regions in China.The results show that there is spatial dependence of enterprise R&D investment,the spatial lags of government R&D subsidy,enterprise R&D investment,and net profit positively affect enterprise R&D investment,that is,enterprise R&D investment,government R&D subsidies and net profits in other regions weighted by economic distance have positive impacts on enterprise R&D investment in local region.
