本土市场规模与能源效率——绿色技术进步、绿色技术效率的调节路径

Home Market Size and Energy Efficiency:Moderated Dual-path of Green Technology Progress and Green Technology Efficiency

使用2001—2017年30个省级层面数据,运用基于非期望产出的超效率SBM模型测度省级层面能源效率指标,借助系统GMM模型实证分析本土市场规模对能源效率的影响及绿色技术进步、绿色技术效率影响本土市场规模作用于能源效率的路径。结果表明:第一,本土市场规模对于能源效率的影响呈“U”型的非线性特征;第二,本土市场规模分别通过绿色技术进步、绿色技术效率对能源效率呈倒“U”型、“U”型的影响特征,两条路径相互独立具有互补性,若形成合力则后期会持续推动能源效率水平的提升;第三,本土市场规模分别与绿色技术进步、绿色技术效率对于能源效率的影响呈显著的门限效应且因地区不同而存在差异。

Based on the Super-SBM Model considering undesirable output and China’s Provincial Panel Data in 2001-2017 to measure energy efficiency indicators at the provincial level,the influence of home market size on energy efficiency and dual moderation paths of green technology progress and green technology efficiency are empirically analyzed in this paper.The results show that:First,the influence of the size of the home market on energy efficiency is showing a U-type non-linear characteristics;Secondly,the influence of home market size on energy efficiency through green technology progress and green technology efficiency is characterized by an inverted U-type and a U-type of impact respectively,and the two paths are independent and complementary.If a combined force is formed,it will play a continuous role in promoting energy efficiency in the later stage.Thirdly,the home market size has significant threshold effect on energy efficiency with green technology progress and green technology efficiency,and it varies with different regions.
