海洋渔业产业结构优化对碳排放效率的影响——基于我国沿海地区的空间计量分析

研究海洋渔业产业结构优化对碳排放的影响,对于促进海洋渔业高质量发展具有重要的现实意义。文章基于2008—2017年我国沿海9省(自治区)的面板数据,运用数据包络方法计算海洋渔业碳排放效率,并采用空间计量模型,探讨海洋渔业产业结构优化对碳排放效率的影响。研究结果表明:我国海洋渔业碳排放效率的地区差异显著,除河北和广西外,其他地区均具有较高的海洋渔业碳排放效率;从空间特征看,海洋渔业产业结构优化水平具有显著的空间集聚性,海洋渔业碳排放效率也存在一定的空间依赖性,碳排放效率的"高-高"集聚特征较为明显;从回归结果看,海洋渔业产业结构优化和海洋渔业经济水平对海洋渔业碳排放效率具有显著的正向影响,这种影响不仅作用于本地区,而且辐射和扩散到邻近地区;渔民收入、渔业科研投入和渔业对外开放水平对海洋渔业碳排放效率存在一定的负面影响。

The Influence of Marine Fishery Industrial Structure Optimization on Carbon Emission Efficiency:Spatial Econometric Analysis Based on Coastal Areas of China

It is of great practical significance to study the influence of optimization of marine fishery industrial structure on carbon emissions for promoting the high-quality development of marine fishery.Based on the panel data of 9 coastal provinces(autonomous region)in China from 2008 to2017.The data envelopment method was used to calculate the carbon emission efficiency of marine fishery,and spatial measurement model was used to explore the impact of the optimization of the industrial structure of marine fishery on the carbon emission efficiency.The results showed that:there were significant differences in the carbon emission efficiency of marine fisheries in China at the provincial level,except Hebei and Guangxi,the other areas had higher carbon emission efficiency of marine fisheries.From the perspective of spatial characteristics,the optimization level of marine fishery industrial structure had a significant spatial agglomeration,and there was a certain spatial dependence on the carbon emission efficiency of marine fishery.The"high-high"agglomeration characteristics of carbon emission efficiency were more obvious.From the regression results,the optimization of marine fishery industrial structure and the economic level of marine fishery had a significant positive impact on the carbon emission efficiency of marine fishery,which not only affected the local area,but also radiated to the adjacent areas.However,the income of fishermen,the input of fishery scientific research and the level of fishery opening to the outside world had some negative effects on the carbon emission efficiency of marine fishery.
