摘要:引入超效率DEA非参数线性规划方法构建了沿海地区蓝绿指数,衡量创造GOP过程中资源消耗、污染排放、环境治理的投入程度,利用Malmquist方法对蓝绿指数变化进行了动态分析。尔后构建了聚类矩阵和收敛指数,进一步发掘沿海地区海洋经济绿色发展的空间集聚趋势及分布特征。结果显示:蓝绿指数十年整体均值并不处于蓝绿前沿面,各地区海洋经济增长对资源消耗、污染排放与环境治理的程度呈现出较大差异性,其中上海、广东、海南的蓝绿指数排名位于前列;蓝绿前沿的变化幅度对沿海地区的蓝绿指数产生了较大正向影响;聚类矩阵中,除上海、广东呈现“双高”外,其他沿海地区均呈现“单偏”型;收敛指数则表明沿海三大经济区域海洋绿色经济发展差距逐渐缩小。

Abstract: The super-efficiency DEA non-parametric linear programming method is introduced to build a blue-green index in coastal areas to measure the degree of resource consumption, pollutant discharge and environmental governance investment. The Malmquist is utilized to analyze the change of blue-green index. Together with it, clustering matrix and convergence index are established to explore spatial agglomeration trends. The results show that the overall mean of blue-green indices in ten years is not in the blue-green frontier, and the coastal areas demonstrate a large difference, in which the blue-green indices of Shanghai, Guangdong and Hainan rank among the top. The changes in the blue-green frontier have a positive impact on blue-green indices of coastal areas. In the clustering matrix, all coastal areas display a "single-bias", except Shanghai and Guangdong. The convergence index indicates that the three major coastal economic zones are narrowing gradually.

十二五发展规划中明确指出海洋经济要做到“绿色发展,统筹考虑海洋生态环境保护与陆源污染防治,加强海洋资源节约集约利用,增强海洋经济可持续发展能力”。那么在我国倡导海洋经济绿色发展过程中,如何科学地把握海洋经济发展过程中的绿色程度?如何判断GOP创造过程中的资源损耗、环境污染的程度?这些问题的探讨有益于提高我国海洋经济可持续发展政策制定的准确性。
关于国家或地区绿色发展程度的研究,现有文献主要通过构建“指数”来衡量绿色水平或程度。……
