中国物流产业效率的时空演化

物流产业是经济发展的重要组成部分,其发展水平和效率提升对国民经济的健康稳定发展举足轻重。基于2007—2016年中国省级面板数据,运用方向距离函数模型测算了中国31省份物流产业效率,采用探索性空间数据分析和标准差椭圆法对中国物流产业发展的空间相关性及时空差异性进行了动态研究。结果表明:在观测年份内,中国物流产业效率总体上呈现下降趋势；物流产业效率区域差异明显,东部略高于中部,西部最低；物流产业效率在空间上呈现显著的正相关性,物流产业效率相似的省域在空间上集聚分布；物流发展的空间差异主要存在于东—西方向,西部地区物流产业发展与中东部地区差距逐渐拉大,其发展重心经历了先向西再向东的移动轨迹。基于上述结论,从培育物流产业发展增长极、优化空间布局以及与其他产业联动发展等角度提出了促进中国省域物流高效协调发展的建议。

Spatio-temporal Evolution of China's Logistics Industry Efficiency

The logistics industry is an important part of economic development. Its development level and efficiency improvement play an important role in the healthy and stable development of the national economy. Based on the Chinese provincial panel data during the years from 2007 to 2016, this paper uses the directional distance function model to calculate the efficiency of logistics industry in various regions of China. The exploratory spatial data analysis method and standard deviation ellipse are used to study the spatial correlation and spatial difference of China''s logistics industry development. The results show that the efficiency of China''s logistics industry has shown a downward trend during the observation year; the regional differences in logistics efficiency are obvious, with the east being slightly higher than the central and the lowest in the west; China''s provincial logistics efficiency presents a significant spatial positive correlation, and the correlation is gradually enhanced, and provinces and cities with similar logistics efficiency are spatially clustered; the spatial difference of China''s logistics development mainly exists in the east-west direction; the development of the logistics industry in the western region and the gap between the central and eastern regions have gradually widened, and its development focus has experienced a trajectory of moving westward and then eastward. Based on the above conclusions, this article gives suggestions from three aspects:cultivating the growth of the logistics industry, optimizing spatial layout, and developing linkages with other industries, with a view to promoting the efficient and coordinated development of China''s provincial logistics.
