川渝地区碳排放效率测度及其影响因素研究

Research on the Measurement of Carbon Emission Efficiency and Its Influencing Factors in Sichuan-Chongqing Region

摘要: 在新的历史发展阶段，经济发展迫切需要低碳转型，节能减排和绿色低碳已成为我国经济发展的重中之重，提高碳排放效率是实现“双碳”目标的同时保持经济高质量发展的关键。本文基于2003~2021年川渝地区22个城市面板数据，采用考虑非期望产出的Super-SBM模型以及Global-Malmquist-Luenberger指数法测算碳排放效率，利用面板Tobit模型探究了区域碳排放效率的因素。结果表明：(1) 碳排放效率变化呈“U”型趋势，已经完成由恶化到进步的转变，碳排放绩效呈加速提高的态势；(2) GML指数显示，碳排放效率增速经历了先迅速上升后逐渐放缓的趋势；(3) 效率分解——2009年后川渝地区整体碳排放水平的提高，由单维的技术进步贡献转变为技术效率和技术进步双重贡献；(4) 土地结构、工业产业结构、政府干预程度、城镇化水平对川渝地区碳排放效率具有显著负向相应。绿色技术创新能力、经济发展水平对川渝地区碳排放效率具有显著正向效应。

Abstract: In the new historical development stage, economic development urgently needs low-carbon transformation, energy saving, emission reduction and green low-carbon has become the top priority of China’s economic development, and improving carbon emission efficiency is the key to achieve the “double carbon” goal while maintaining high-quality economic development. Based on the panel data of 22 cities in Sichuan and Chongqing region from 2003 to 2021, this paper uses the Super-SBM model considering non-expected output and the Global-Malmquist-Luenberger index method to measure carbon emission efficiency, and uses the panel Tobit model to explore the factors of regional carbon emission efficiency. The results show that: (1) The change of carbon emission efficiency shows a U-shaped trend, which has completed the transformation from deterioration to progress, and the carbon emission performance shows an accelerated trend of improvement; (2) GML index shows that the growth rate of carbon emission efficiency has experienced a trend of rapid rise and then gradual slowdown; (3) Efficiency decomposition—the improvement of the overall carbon emission level in Sichuan and Chongqing region after 2009 has changed from the single-dimensional contribution of technological progress to the dual contribution of technological efficiency and technological progress; (4) Land structure, industrial structure, government intervention degree and urbanization level have significant negative corresponding effects on carbon emission efficiency in Sichuan and Chongqing region. Green technology innovation ability and economic development level have significant positive effects on carbon emission efficiency in Sichuan and Chongqing region.
