Abstract: Biased technological progress is significant to economic growth and energy conservation of China. Scholars and policy makers are very concerned about whether carbon emission price can solve negative externalities of corporate emissions. Based on the data of 190 cities in China and above from 2007 to 2016, this paper uses the Malmquist index to estimate the input biased technical change index and its features in the save of energy factor, tests the abatement effect of biased technological progress and carbon emission price. Based the data of 25 pilot carbon emission trading cities, this paper confirms moderating effect of carbon emission price on the abatement effect of biased technological progress. This study finds that: (1) From the input biased technical index, the overall biased technological progress index is bigger than 1 but shows a downward trend of volatility. (2) From the bias/direction of biased technological progress, in the sample cities, the bias/direction of biased technological progress in energy and capital is biased towards energy-saving cities accounted for 53%, the bias/direction of biased technological progress in energy and labor is biased towards energy-saving cities accounted for 46%. (3) From the abatement effect, biased technological progress has significant emission reduction effect. Carbon emission price has not significant emission reduction effect. (4) From the moderating effect, the carbon emission trading price has a significant moderating effect on the emission reduction effect of biased technological progress. This paper provides a theoretical reference for further promoting the construction of the national carbon emission trading market and the government to formulate reasonable emission reduction policies.

摘要： 有偏技术进步及其要素偏向性对中国实现经济增长与节能减排的“双赢”有着重要意义。而碳排放权交易价格能否将二氧化碳排放的负外部性“内部化”，从而达到预期减排效果是政界与学界所共同关注的问题。本文收集2007—2016年190个中国地级及以上城市数据，使用非参数指数分解法测定了其有偏技术进步指数及能源要素节约偏向，检验了有偏技术进步与碳排放权交易价格的减排效应，并基于25个碳排放权交易试点城市数据验证了碳排放权交易价格对有偏技术进步减排作用的调节效应。研究发现：（1）从测算结果来看，总体上有偏技术进步指数大于1但呈现波动下降趋势；（2）从要素偏向来看，有偏技术进步在能源与资本、能源与劳动间偏向节约能源的城市占比分别为54%与46%；（3）从减排效应来看，有偏技术进步存在显著的减排效应，但碳排放权交易价格单独产生的减排效应并不强；（4）从调节效应来看，碳排放权交易价格对有偏技术进步的减排作用存在显著的调节效应。本文为进一步推进全国碳排放权交易市场的建设与政府制定合理减排政策提供了理论参考。
