【摘要】：鉴于污染指标的不易测度,前人研究海洋渔业经济时极少从定量角度关注非期望产出。本文以海洋天然渔业水域污染所造成的负效应作为非期望产出,采用SBM(Slacks Based Measure)模型,对2004—2015年中国沿海11个省市区的海洋渔业经济效率进行评价,在此基础上采用Kernel密度和Tobit模型分析各省市区海洋渔业经济效率时空演化格局及其影响因素。研究结果表明:(1)基于时间序列视角,中国海洋渔业经济效率值持续低迷,说明近年来中国海洋渔业经济转型升级规制尚未发挥预期的效果;(2)基于时空视角,中国沿海11个省市区的海洋渔业经济效率呈现两极分化态势,且未得到有效改善,说明中国沿海地区渔业经济发展水平失衡;(3)基于全局视角,中国海洋渔业经济效率整体偏低,说明中国海洋渔业经济发展速度较迟缓;(4)基于产业结构视角,第一产业比重过高是影响中国整体海洋渔业经济效率持续走低的主因,技术水平偏低是影响海洋渔业经济效率的关键,说明中国海洋渔业产业结构继续沿用传统的以第一产业为主的模式在运行。为扭转渔民就业专业化水平与效率的负向关系,渔业转产转业政策需提质增效。未来中国海洋渔业经济转型面临体制转型和结构转型双重挑战。在以制度创新引领体制转型升级前提下,根据中国沿海11个省市区的不同资源禀赋,调整产业结构,优化区域布局,走特色差异化创新发展之路是提高海洋渔业经济效率的可选路径。
[Abstract]:In view of the difficulty to measure the pollution index, the previous studies of marine fishery economy seldom focus on the non-expected output from the quantitative point of view.In this paper, the negative effects caused by pollution in marine natural fishery waters are taken as non-expected outputs, and the economic efficiency of marine fisheries in 11 provinces and municipalities of China from 2004 to 2015 is evaluated by using SBM(Slacks Based measure model.On the basis of this, Kernel density and Tobit model were used to analyze the spatial and temporal evolution pattern of economic efficiency of marine fishery in various provinces and cities and its influencing factors.The results show that based on the time series perspective, the economic efficiency of China's marine fisheries remains low, indicating that in recent years China's economic transformation and regulation of marine fisheries has not played the expected effect.The economic efficiency of marine fishery in 11 provinces and municipalities along the coast of China shows a trend of polarization and has not been effectively improved, indicating that the level of fishery economic development in China's coastal areas is out of balance) based on the overall perspective, the overall economic efficiency of China's marine fishery is on the low side.Based on the perspective of industrial structure, the high proportion of primary industry is the main reason that affects the economic efficiency of marine fishery in China as a whole.The low level of technology is the key to the economic efficiency of marine fishery, which indicates that the structure of China's marine fishery industry continues to follow the traditional primary industry model in operation.In order to reverse the negative relationship between the level of employment specialization and the efficiency of fishermen, it is necessary to improve the quality and efficiency of the policy.In the future, the economic transformation of China's marine fishery will face the dual challenges of institutional transformation and structural transformation.Under the premise of system innovation leading the system transformation and upgrading, according to the different resource endowment of 11 provinces and municipalities along the coast of China, the industrial structure should be adjusted to optimize the regional layout.It is an alternative way to improve the economic efficiency of marine fishery by taking the road of characteristic differentiation innovation and development.
