中国海洋经济绿色发展效率评价研究

Research on evaluation of green development efficiency of China's marine economy

运用三阶段DEA方法,对中国11个沿海地区的海洋经济绿色发展效率进行测算,在第二阶段剔除了环境因素和随机因素的影响,在相对较为公平的条件下分析测算中国11个沿海地区的海洋经济绿色发展效率。结果表明,①引入SFA对环境变量进行剔除之后得到的效率值更符合实际情况;②当前中国的海洋经济绿色发展效率整体相对较低,海洋经济发展与资源环境保护之间矛盾较为突出;③天津、上海、山东、广东的海洋经济绿色发展效率值相对较高,辽宁、江苏、浙江、福建的海洋经济绿色发展效率值处于中等,河北、广西、海南的海洋经济绿色发展效率值相对较低;④海域使用权确权面积、涉海就业人员数增长反而会导致生产率下降,海洋环境保护区数的增长对海洋经济绿色发展效率值有利,加强对海域使用权确权面积的有效管理、积极调整优化人才结构、适当增加海洋环境保护区的设立数量,是促进海洋经济绿色发展的有效途径。

This study used the three-stage DEA method to measure the marine economy green development efficiency in 11 coastal ar⁃eas of China.In the second stage,the influence of environmental factors and random factors were eliminated.,and the marine economy green development efficiency of 11 coastal areas in China were analyzed and calculated under relatively fair conditions.The results showed,①the efficiency value obtained after the introduction of SFA to eliminate environmental variables was more in line with the ac⁃tual situation;②the current China’s marine economy green development efficiency was relatively low,and the contradiction between marine economy development and resources and environmental protection was more prominent;③the marine economy green develop⁃ment efficiency value in Tianjin,Shanghai,Shandong,Guangdong were relatively high,the marine economy green development effi⁃ciency value in Liaoning,Jiangsu,Zhejiang,Fujian were at the medium level,and the marine economy green development efficiency value in Hebei,Guangxi,Hainan were relatively low;④the increase of the area of sea area use rights and the number of employment personnel involved in the sea will lead to the decline of production rate,and the increase of marine environmental protection zones was beneficial to the marine economy green development efficiency.Strengthening the effective management of the area of the right to use the sea area,actively adjusting and optimizing the talent structure,and appropriately increasing the number of marine environmental protection zones,may be effective ways to promote the green development of marine economy.
