基于资源、环境与治理行为的相互依存性,本文给出了考虑政府治理行为时海洋经济绿色生产率的评估。结合RAM模型和Malmquist指数的优势,构建了包含非期望产出的Malmquist-RAM-Undesirable模型,对我国海洋经济绿色生产率投入产出要素的松弛变量进行了分析,揭示各投入冗余和产出不足及需改进的比例。研究结果显示:考虑政府治理行为后,效率偏低是导致海洋经济绿色生产率低于传统生产率的主要原因。五年发展计划中政府的治理力度与海洋经济的绿色生产率呈V型相关。在省域层面考虑了政府的治理行为后,上海、广东能够较好地平衡海洋经济增长与海域资源市场化和海洋环境的治理,而其他地区仍然需要通过技术改进和海洋资源市场化改革来内化污染治理成本,推动投入产出变量到达生产前沿,实现海洋经济可持续发展。政府对环境治理投资逐年加强,然而由于治理方式的不恰当,并未取得理想的经济价值。
Based on the mutual dependence of resources, environment and governance behavior, this paper presents the assessment on the green productivity of marine economy in the governance framework. The RAM-Undesirable model is introduced into the traditional Malmguist index to analyze the slack variable of input-output factors and green productivity of China's marine economy and discover the input redundancy, output deficiency and the improved proportion of input-output factors. The results show that the control behavior and the low technical efficiency are the main reasons for the low productivity of marine economy. The relationship between the five-year development plan and the green productivity of the marine economy presents "V" type. After considering the governance factors in the provincial level, Guangdong and Shanghai have developed in balance. In the future, both the state and local governments should insist on internalizing the cost of pollution treatment through technology improvement and marketization reform of marine resource. The investment in environmental governance has been strengthened year by year. However, the fault governing forms have resulted in the lower economic value.
