Renewable energy technological innovation (RETI) is an important way to reduce carbon emissions and achieve sustainable development. Exploring whether RETI is beneficial to the improvement of carbon emission efficiency and how the market environment affects the role of RETI on carbon emission efficiency is critical to the design of effective policies. Therefore, based on the data from 25 provinces in China from 2002 to 2015, the Tobit fixed-effect model and the panel threshold model are used to investigate the impact and the mechanism of RETI on total factor carbon performance index (TCPI) from a market perspective. The results show that: (1) RETI can effectively improve TCPI, but this effect is affected by market factors; (2) With the reduction of market segmentation or the increase of market potential, the improvement effect of RETI on TCPI is significantly enhanced; (3) The panel threshold model further verifies that the impact of RETI on TCPI has a significant single threshold effect in terms of market segmentation and market potential; (4) There is an inverted "U-shaped" relationship between market segmentation and TCPI, and the increase of market potential is conducive to the improvement of TCPI. This paper provides corresponding policy implications for China to achieve the dual goals of economic transformation and carbon emission reduction.
可再生能源技术创新（RETI）是减少碳排放、实现可持续发展的重要途径。探索 RETI 是否有利于提高碳排放效率，以及市场环境如何影响 RETI 对碳排放效率的作用，对于制定有效的政策至关重要。因此，本文利用 2002-2015 年中国 25 个省份的数据，基于市场视角，采用 Tobit 固定效应模型和面板门槛模型，从实证角度研究了 RETI 对全要素碳绩效指数（TCPI）的影响及其作用机制。结果表明：（1）RETI 能有效提高 TCPI，但这种效应受到市场因素的影响；（2）随着市场分割程度的降低或市场潜力的增加，RETI 对 TCPI 的改善效应显著增强；（3）面板门槛模型进一步验证了 RETI 对 TCPI 的影响在市场分割和市场潜力方面存在显著的单一门槛效应；（4）市场分割与 TCPI 之间存在倒“U 型”关系，市场潜力的增加有利于 TCPI 的提高。本文为中国实现经济转型和碳减排的双重目标提供了相应的政策启示。
