中文摘要:

      基于要素资源配置效应、技术创新效应和竞争效应，本文梳理了市场分割对长江经济带能源环境效率的影响机制，基于省际面板数据实证检验，发现：长江经济带能源环境效率随着市场分割程度存在显著倒“U”形关系；在规模报酬递减作用下，市场分割对长江经济带能源环境效率的影响从提升转变为抑制。未来破除长江经济带能源环境效率提升瓶颈的关键在于研发投入、对外开放水平以及市场融合。另外，分样本回归表明市场分割导致长江经济带中游地区能源环境效率存在“中部塌陷”的风险。由此，加强研发资金的精准投入、提升对外开放度和中游地区支撑力，以及增强长江经济带生态协同是长江经济带提升能源环境效率的重要突破口。

英文摘要:

      Based on the effects of factor resource allocation, technological innovation and competition, this paper combs the influence mechanism of market segmentation on the energy and environmental efficiency of the Yangtze River economic belt. Based on the empirical test of provincial panel data, it is found that: the energy and environmental efficiency of the Yangtze River economic belt has a significant inverted “U” relationship with the degree of market segmentation; under the effect of diminishing returns to scale, the impact of the market segmentation on the local energy and environmental efficiency has changed from promotion to inhibition. In the future, the key to breaking the bottleneck of energy and environmental efficiency improvement in the Yangtze River economic belt lies in R & D investment, opening-up level and market integration; in addition, regression analysis shows that market segmentation leads to the risk of “central collapse” of energy and environmental efficiency in the middle reaches of the Yangtze River economic belt. Therefore, speeding up the integration process of the Yangtze River economic belt, enhancing the ecological synergy, accurately investing in R&D funds, enhancing the openness and the support of the middle reaches zone along the coast of Yangtze river are important breakthroughs in improving the energy and environmental efficiency of the Yangtze river economic belt.
