蓝色粮仓背景下我国海水养殖业绿色技术进步测度、方向性评价与优化研究

Faced with the dual pressure of food security and severe marine environmental constraints brought by population growth, China must rely on green and eco-environment-friendly technological progress in the process of building and developing the blue barn in the fields of marine aquaculture.Therefore, this project will take sea area as resourse factor and eco-environment pollution as undesirable output into the framework of technological progress analysis, and use the parametric method, non-parametric method to build measurement model of green technological progress to measure the level of green technology of China's mariculture industry. Further this project will use of undesirable outputs into translog cost production function and the expansion of the DEA-Malmquist in order to measure and evaluate the bias of green technological progress. Then the coupling coordination model is used to analyze the coupling degree of the bias of green technology progress and the factor endowment. Based on these, factor models are built to analyze how to improve China's mariculture green technological progress level, and how to improve the coupling degree between direction of the path of aquaculture green technology progress and the factor endowment. Finally, the project put forward corresponding countermeasures and suggestions.

面临人口增长所带来的粮食安全以及较为严峻的海洋生态环境约束的双重压力，我国在牧海耕渔、发展海水养殖业，构建蓝色粮仓过程中必须依赖绿色技术进步，走生态环境友好型技术进步。为此，本课题将表示资源因素的海域及表示生态环境污染的非期望产出纳入到技术进步分析框架，运用参数法、非参数法等方法构建绿色技术进步测度模型，对我国海水养殖业的绿色技术进步水平进行测度。进一步运用考虑非期望产出的超越对数成本函数以及拓展的DEA-Malmquist模型，对我国海水养殖业绿色技术进步的方向性进行了评价，并构建耦合协调模型对我国海水养殖业绿色技术进步方向与要素禀赋的耦合协调度即绿色技术进步方向的合意性进行了分析。在此基础上，构建影响海水养殖业绿色技术进步水平及技术进步方向合意性的因素模型，分析确定促进我国海水养殖业绿色技术进步水平及技术进步方向合意性的优化路径，最后，提出了相应的政策建议。

面对人口增长所带来的粮食安全以及海洋生态环境约束的双重压力，我国在耕海牧渔，发展海水养殖业，构建蓝色粮仓过程中必须依赖绿色技术进步。本课题运用非参数的DEA模型构建资源环境约束下的绿色技术进步测度模型，对我国海水养殖业绿色技术进步水平进行了测度，发现我国海水养殖业绿色技术进步水平总体呈现波动上升趋势。结合海水养殖业发展的现实情况，选取影响因素指标体系，分析海水养殖业绿色技术进步的影响因素。进一步从投入和产出视角分析研究分析了我国海水养殖业绿色技术进步方向性评价的问题。从投入视角，分析海水养殖业技术进步在资本、劳动和海域两两要素组合之间的具体偏向，发现技术进步在资本与劳动之间稳定偏向于使用资本、节约劳动；技术进步在资本与海域之间多数偏向于使用资本、节约海域；技术进步在劳动与海域之间相对偏向于使用海域、节约劳动。对海水养殖业的投入偏向与要素禀赋情况是否匹配进行判别分析。从产出视角，将海水养殖业的污染物作为非期望产出纳入测度体系，测度海水养殖业的技术进步在期望产出与非期望产出之间的具体偏向，发现技术进步呈现绿色产出偏向但偏向程度需要进一步提高。基于上述研究，课题提出了提升我国海水养殖业绿色技术进步水平以及优化绿色产出偏向水平的对策建议。
