中国上市公司研发效率及其影响因素分析——基于2007—2014年中国上市公司的经验数据

Analysis on R&D Efficiency of China's Listed Company and Its Influencing Factors:Based on Empirical Evidence of China's Listed Companies from 2007to 2014

基于2007—2014年中国深沪上市公司的非平衡面板数据,构建DEA模型测度了上市公司的研发效率,从时间和空间维度分析了其收敛性,并考察了人才结构、专利保护程度和全球化战略对上市公司研发效率的影响。结果表明:东部地区上市公司的研发效率优于中、西部地区的上市公司,但后者有追赶前者的趋势;在上市公司研发效率的影响因素中,专利保护程度以及上市公司全球化战略与研发效率之间存在显著的正相关关系;大专以上学历与上市公司研发效率之间存在显著的正相关关系,而大专以下学历与上市公司研发效率之间存在不显著的负相关关系。

Based on the unbalanced panel data of China＇s listed companies from 2007 to 2014,this paper measures the RD efficiencies of listed companies by using the DEA model,and analyzes the convergence of RD efficiencies of listed companies from the perspective of time and space.Then it tests the influences of patent protection,globalization strategy and talent structure on RD efficiencies of listed companies.The result shows as follows：the RD efficiencies of listed companies in eastern region are better than those of listed companies in central and western regions,but the latter is catching up the former;about the factors influencing RD efficiency of listed company,patent protection degree,listed company＇s globalization strategy is significantly positive correlation with RD efficiency;university degree or above is significantly positive correlation with RD efficiency of listed companies,there is no significant negative correlation between below-college degree and RD efficiency of listed companies.
