区域绿色工业企业技术创新效率空间效应研究

工业企业的绿色发展是可持续发展的重要一环,因此须在提高工业企业创新效率的同时,控制节能减排。文章将"工业三废"放入技术创新效率的评价体系中,采用非期望SBM模型测度我国30个省份2009-2015年工业企业绿色技术创新效率,以此为基础,引入空间杜宾模型重点分析若干解释变量绿色技术创新效率的空间效应。结果表明:1)我国工业企业绿色技术创新效率有逐年上升之势,整体水平偏低,东、中、西、东北部存在明显的区域差异;2)该效率在全国范围内存在明显的空间扩散效应,地区间技术交流成效显著;3)政府科技支持、技术转化水平、交通基础设施和对外开放程度对该效率存在显著的空间直接效应,而技术转化水平、人力资本水平和对外开放程度对该效率存在显著的空间间接效应。

SPATIAL EFFECT OF TECHNICAL INNOVATION EFFICIENCY OF REGIONAL GREEN INDUSTRIAL ENTERPRISES

Green growth of industrial enterprises is a key element in sustainable development, which requires industrial enterprises to increase innovation efficiency and to control energy-saving-emission-reduction. This paper, putting three industrial wastes into the evaluation of technical innovation efficiency, uses SBM model to estimate their green technical innovation efficiency of industrial enterprises in China's 30 provinces during 2009 to 2015, and employs Durbin model to analyze their spatial effects of some variables on green technical innovation efficiency. The outcome shows a rising trend of green technical innovation efficiency, generally in a low level, varying among eastern, central, western and northeastern. In the whole China, this efficiency exhibits an apparent spatial diffusion with good achievement in regional technical exchanges. A direct spatial effect on this efficiency comes from governmental supports on scientific technology, technical conversion level, infrastructures and openness, and an indirect spatial effect comes from human capital level.
