中文摘要:

      为量化2000-2016年长江经济带水资源消耗量对经济增长的约束程度，本文在科布道格拉斯生产函数中加入水资源要素，构建改进的Romer增长阻尼模型进行实证分析。结果显示：①研究期内长江经济带水资源增长阻尼系数总体稳定，水资源对经济增长的约束作用程度经历了明显的强弱变化；②研究期内水资源增长阻尼显著降低并趋向平稳，说明水资源对长江经济带经济增长的约束作用减弱并逐渐稳定；③浙江、上海、江西等7个省份存在明显的水资源增长阻尼，区域差异显著。由此，本文建议：长江经济带各省市应提升水资源利用效率，同时加大资本投入、优化劳动力结构，在区域协调发展方面可构建水权交易机制，以期使长江经济带在水资源"大保护"约束下实现经济的持续发展。

英文摘要:

      In order to quantify the constraint degree of water resource consumption against economic growth in the Yangtze River Economic Belt from 2000 to 2016, this study make empirical analysis after constructing an improved Romer growth damping model by adding water resource element into the Cobb Douglas production function. The results show that the damping coefficient of water resource growth is generally stable in the Yangtze River Economic Zone, while the degree of influence fluctuates significantly during the study period. During the research period, the water resources growth damping has decreased significantly and tended to be stable, indicating that the restraint effect of water resources on the economic growth of the Yangtze River Economic Belt has weakened and gradually stabilized. There are obvious water resources growth damping in seven provinces and cities, such as Zhejiang, Shanghai and Jiangxi, with significant regional differences. The finding suggests that the provinces in the Yangtze River Economic Belt should improve the efficiency of water resource utilization, increase capital investment and optimize the labor structure. In the area of regional coordinated development, water rights trading mechanism can be established to achieve sustainable economic development under the restraint of the Great Protection of water resource in the Yangtze River Economic Belt.
