摘　　要：尽管偏向技术进步被视为可再生能源消费最重要的驱动因素之一,但现有研究普遍忽视其对可再生能源转型的影响。基于偏向技术进步理论框架,运用固定效应随机前沿生产函数分析技术进步的偏向性以及化石能源与可再生能源间的替代弹性,进而判断2000—2017年中国内地各省域的偏向技术进步是否推动了可再生能源转型。研究发现,整体上技术进步在化石能源与可再生能源间偏向于使用更多化石能源,且二者之间具有替代关系,这表明整体上偏向技术进步不利于可再生能源转型。分省域看,仅有上海、浙江和湖北的技术进步偏向于使用更多可再生能源,且可再生能源能够有效替代化石能源,这表明上述省份的偏向技术进步有利于可再生能源转型。Although biased technological progress is regarded as one of the most important driving factors of renewable energy consumption,existing studies ignore its impact on renewable energy transition.Based on the theoretical framework of biased technological progress,this paper analyzes the bias of technological progress,and estimates the substitution elasticity between fossil energy and renewable energy by using the fixed effect stochastic frontier production function.The impact of biased technological progress on renewable energy transiton in 30 Chinese provinces from 2000 to 2017 is tested.The results show that,as a whole,technological progress tends to use more fossil energy between fossil energy and renewable energy,and there is a substitution relationship between them.This shows that biased technological progress is not conducive to renewable energy transition.From the perspective of provinces,only Shanghai,Zhejiang and Hubei’s technological progress tend to use more renewable energy,and renewable energy can effectively replace fossil energy.This shows that technological progress in these provinces is conducive to renewable energy transition.
