中国休闲渔业发展质量测度与区域差异研究

Research on development quality measurement and regional difference of Chinese recreational fishery

从经济发展质量的内涵和外延出发,构建休闲渔业发展质量测度指标体系,采用综合指数法对中国29个省份2009—2018年的休闲渔业发展质量进行测度,并运用基尼系数(Gini)、泰尔指数(GE1)及对数离差均值(GE0)全面衡量休闲渔业发展质量的区域差异和演进趋势。研究发现:中国休闲渔业发展质量存在明显的区域差异,呈现出从沿海向内陆地区梯度递减的空间格局特征。休闲渔业发展质量处于中游的省份区域差异程度较大,而处于两端的省份区域差异程度相对较小,且区域差异总体上有逐渐缩小的趋势;休闲渔业发展质量区域差异最大的是中部地区,西部次之,东部最小,呈现倒“U”型特征。2015年以后,三大区域休闲渔业发展质量差异呈现明显的分化格局,东中西部区域内差异是影响中国休闲渔业发展质量区域差异的主要因素。

Based on the connotation and extension of the quality of economic development,the present study built an index system for the quality of recreational fishery development,adopted the comprehensive index method to measure the quality of recreational fishery development in 29 provinces of China from 2009 to 2018,and used the Gini coefficient(Gini),Theil index(GE1)and the mean logarithmic deviation(GE0)to comprehensively measure the regional differences and evolution trends of the development quality of recreational fishery.The present study found that there was an obvious regional difference in the development quality of recreational fishery in China,which was manifested as a gradient decline from coastal to inland areas.The regional differences in the quality of recreational fishery in the middle reaches were relatively large,while the regional differences in the provinces at both ends were relatively small,and the regional differences generally tend to shrink gradually.The largest difference was in the central region,followed by the west,and the smallest in the east,showing an inverted“U”shape.After 2015,the differences in the quality of recreational fishery development in the three major regions showed a clear pattern of differentiation.The intra-regional differences in the east,central,and west were the main factors affecting the regional differences in the quality of recreational fishery development in China.
