Abstract: Huai river basin has entered into green development dilemma with slowing down economy and severe environmental pollution. This paper, based on green development theory, discusses the features of this dilemma from ecological efficiency, and combined with development history and situation of Huai river basin, and studies theoretically the conducting mechanism. Malmquist index is used to measure its ecological efficiency. It is concluded that a low ecological efficiency contributes to the green development dilemma. Panel data model is applied to analyze the factors of low ecological efficiency. Resource industries play a critical role to others. Adjustment of single industry or some factors can not resolve the dilemma. Huai river basin should begin from laws, optimizing industrial structure and scientific talents, promote technical advances and increase ecological efficiency so as to resolve the green development dilemma. 

Key words: Huai river basin, ecological efficiency, green development, eco-technical advance rate 

摘要： 着力破解陷入经济增长减缓和环境污染严重的绿色发展困境，已经成为淮河流域未来实现高质量发展的关键所在。基于绿色发展理论，从生态效率角度，结合淮河流域的发展历史与现状，探析了淮河流域绿色发展困境的表现和特征，并从理论上对导致淮河流域绿色发展困境的传导机制进行了深入探讨。以生态效率为评价手段，利用Malmquist指数对其进行测算，实证检验了生态效率低下是导致淮河流域陷入绿色发展困境的根本所在。利用面板数据模型，客观分析了影响淮河流域生态效率低下的内在因素，结果显示，淮河流域资源型产业对其他各产业发展起到关键性影响，因此，仅对单个产业或某些因素进行调整无法根本解决淮河流域绿色发展面临的种种难题。为此，淮河流域应当主要从健全法制体系、优化产业结构和引进科研人才三方面入手，促进技术进步，提升生态效率，破解绿色发展困境。
