摘要
基于价值链视角,运用超效率DEA模型测度2005—2014年中国30个省市工业企业绿色创新的整体及分阶段效率,并采用空间面板模型检验其空间溢出效应。结果表明:企业绿色创新的整体及分阶段效率均不高,区域差异明显;在地理距离权重矩阵下,整体及分阶段效率存在显著的正向溢出效应,而基于社会经济距离的外溢效应并不显著,且科技研发阶段的外溢效应强于成果转化阶段;开放度和产业结构与分阶段效率正相关,知识产权保护对本地区和邻区的科技研发分别产生了负向和正向效应。
From the angle of value chain, we use the Super-DEA model to analyze the total and two-stage green innovation effi- ciency of industrial enterprises in 30 provinces from 2005 to 2014. On this base, the spatial econometric model is constructed to exam- ine the spatial spillover effects of green innovation efficiency. The empirical results show us as follows： firstly, the total and two-stage green innovation efficiency in industrial enterprises, with obviously regional differences, have much space to improve; secondly, based on the weight matrix of geographic distance, there is a positive spatial spillover effect, which is not significant under the weight matrix of socioeconomic distance. Meanwhile, the spillover effect in the stage of R＆D is much stronger than that in the stage of S＆T; thirdly, the openness and industrial structure both have positive effects on the two-stage green innovation efficiency. In addition, the opposite effect from the intellectual property protection could occur separately in local and neighboring regions.
