摘要
海洋生态系统是蓝碳的主要贡献者,提高海洋生态效率对促进海洋经济增长、保护海洋生态环境具有重要意义。论文基于三阶段DEA模型,从海洋能源消耗、海洋环境污染以及海洋经济水平三个维度构建海洋生态效率评价指标体系,对我国沿海11个省市的海洋生态效率进行评价,并分析海洋生态效率的主要影响因素。结果表明,我国海洋生态效率呈现“北低南高”的空间格局,其原因主要在于能源和产业结构以及各地政策等方面的区域差异。在此基础上,提出发展建议,为促进海洋领域支撑双碳目标的实现提供理论参考。
Marine ecosystem is the main contributor to blue carbon.It is of great significance to study how to improve marine ecoefficiency to promote economic growth and protect the environment.Based on the three-stage DEA model,the marine ecological efficiency evaluation index system is established from the perspectives of marine energy consumption,marine environmental pollution and marine economic.Then the marine ecological efficiency of 11 provinces or cities along the coast of China is evaluated.The results show that:The marine eco-efficiency in China presents a trend of“low in the north and high in the south”.It is mainly due to the regional differences in energy and industrial structure as well as local policies.Finally,corresponding suggestions are put forward to provide theoretical reference for the realization of the carbon goal in the marine field.
