环境约束下中国战略性新兴产业的技术创新效率研究

摘要从产业维度和地区维度出发,引入资源环境因素,运用SBM(Slack-based Measure)方向性距离函数和GML(GlobalMalmquist-Luenberger)指数,测算了2005—2014年中国战略性新兴产业的环境技术创新效率增长值,并将其分解为技术效率、技术进步、规模效率和技术规模四个影响因子。研究结果显示,在产业维度下,中国战略性新兴产业整体环境技术创新效率偏低,原因在于技术效率和规模效率的显著下降;在区域维度下,战略性新兴产业的环境技术创新效率从东向西依次减弱,且空间集聚性显著,但不同地区的增长渠道各不相同;考虑环境因素的GML指数总体低于不考虑环境因素的GML指数,其原因在于污染排放这一“坏”的产出拉低了地区环境技术创新效率。

Abstract： Using the Slack-Based Measure directional distance function and Global Malmquist-Luenberger index, this paper measures the growth of environmental technology innovation efficiency in strategic emerging industry in China from 2005 to 2014 from the perspectives of industry and region. It then decomposes this growth into 4 influencing factors, namely technical efficiency, technical progress, scale efficiency and technology scale. The results show that the overall technology innovation efficiency of China’s strategic emerging industry is low due to the drastic drop in technical efficiency and the efficiency of scale. In regional dimension, the efficiency of technological innovation in China’s strategic emerging industry decreases from east to west, with significant spacial agglomeration and distinct growth channel. GML index taking account of environmental factors is generally lower than that excluding environmental factors, which is due to the fact that pollution discharge reduces the efficiency of regional environmental technology innovation.

Keywords： Strategic Emerging Industry Environmental Technology Innovation Efficiency SBM Directional Distance Function GML Index
