中国省份绿色技术效率的趋同测试及影响因素分析：1998-2012年

An Convergence Testing and Influencing Factors Analysis of the Green Technology Efficiency of Chinese Provinces:1998-2011

摘要:

改善绿色技术效率能够在既定投入下增加期望产出并减少非期望产出,它和技术进步一样都是经济可持续发展的重要源泉。中国省份绿色技术效率的测度、趋同和影响因素的经验分析表明：省际绿色技术效率差异较大但存在显著的β趋同和θ趋同；对外开放和城镇化有助于改善绿色技术效率,而能源投入强度、经济发展水平和环境规制水平与绿色技术效率负相关,科技水平的影响不明显。为改善绿色技术效率,我们可借助于扩大对外开放与合作、推进新型城镇化和加快节能减排技术研发等多种手段。

Abstract:

The improvement of green technology efficiency can increase desirable output and reduce undesirable one under given input, and it is the important source of economic sustainable development as well as technological progress. The empirical results of the measuring, convergence testing and influencing factors analyzing of Chinese provinces’ green technology efficiency are as the following:the provincial green technology efficiency differences largly but there is a significant β convergence and θ convergence; opening to the outside world and urbanization helps improve green technology efficiency, but energy input intensity, economic development level and environmental regulation level are negatively related to green technology efficiency, and the affect of science and technology level is not obvious. In order to improve green technology efficiency, we can expand opening to the outside world and cooperation, promote the new urbanization, and speed up technology R D of energy saving and emission reduction, and others.
