“双碳”目标下绿色投资促进能源效率提升的空间效应研究

张水平 龙爽 齐美东

摘 要：生态恶化、资源枯竭已经成为经济高质量发展的主要障碍，因此提高能源利用效率，降低碳排放，走绿色低碳发展之路迫在眉睫。文章选取2010—2019年30个省区市的面板数据，运用空间杜宾模型，考察了绿色投资对能源效率的空间溢出效应。结果表明，绿色投资对能源效率的影响具有促进作用，且存在区域性差异，中部地区绿色投资对能源效率的促进作用最大，东部次之，西部最小。区域差异的主要原因是东部地区经济发展水平相对较高，绿色投资规模和能源效率虽然产生了规模递减效应，但是都处于比较高的水平，而西部地区发展水平较低、动力不足，导致绿色投资促进作用有限；东部和中部地区具有正向空间溢出效应，而西部地区由于教育水平较落后、技术人才匮乏而具有负向空间溢出效应。

Abstract： Ecological deterioration and resource depletion have become major obstacles to high-quality economic development， so it is urgent to improve energy efficiency， reduce carbon emissions and take the road of green and low-carbon development. Using panel data of 30 provinces from 2010 to 2019， this paper investigates the spatial spillover effects of green investment on energy efficiency using the spatial Dubin model. The results show that green investment has a promoting effect on energy efficiency， and there are regional differences. The promoting effect of green investment on energy efficiency is the largest in the central region， followed by the eastern region and the western region. The main reason for the regional differences is that the economic development level of the eastern region is relatively high. Although the scale of green investment and energy efficiency have a decreasing effect， they are both at a relatively high level， while the development level of the western region is low and the lack of power leads to the limited promotion effect of green investment. The eastern and central regions have a positive spatial spillover effect， while the western region has a negative spatial spillover effect because of the backward education level and lack of technical talents.

新常态下，传统粗放型增长方式已难以为继。党的二十大报告指出要坚持“绿水青山就是金山银山”的理念，加快推动产业结构、能源结构、交通运输结构等的调整优化。要实现此目标，关键在于保障经济增长的同时，兼顾降低能源消耗和减少污染物排放。……
