长江经济带省域物流效率及时空演化研究

基于2007~2017年长江经济带物流行业发展数据,采用DEA模型、ArcGIS和空间自相关分析方法,测算长江经济带11个省市的物流效率值及时空演化规律。结果表明:2007~2017年长江经济带物流效率波动平缓,综合技术效率平均值为0.830,纯技术效率整体大于规模效率,下游地区的物流综合技术效率、纯技术效率和规模效率均大于中游和上游地区。空间上,长江经济带物流效率高值区主要分布在整个下游地区和中游部分地区,低值区则多为上游地区,整体呈“块状”分布。空间关联性上,2007~2017年,Global Moran's I显著为正,长江经济带各省市物流效率呈现空间正相关性,物流效率相近的省市在空间上集聚分布。最后,为促进长江经济带物流行业区域协调发展,提出如下建议:不断促进产业转型升级;加强区域合作,完善基础设施建设;加大内陆地区对外开放力度和建立大型的物流园区。

Evolution of Time and Space Efficiency of Provincial Logistics in the Yangtze River Economic Belt

Based on the development data of the logistics industry in the Yangtze River Economic Belt from 2007 to 2017, the research uses the DEA model, ArcGIS and spatial autocorrelation analysis method to calculate the logistics efficiency value and time-space evolution law of 11 provinces and cities in the Yangtze River Economic Belt. The results show as follow. From 2007 to 2017, the logistics efficiency fluctuated smoothly in the Yangtze River Economic Zone. The average comprehensive technical efficiency was 0.830, which did not realize the efficiency of logistics. Pure technical efficiency is greater than scale efficiency as a whole. The comprehensive technical efficiency, pure technical efficiency and scale efficiency of logistics in downstream areas are higher than those in midstream and upstream areas. Spatially, the high value areas of logistics efficiency in the Yangtze River Economic Belt are mainly distributed in the lower and middle reaches, while the low value areas are fixed in the upper reaches. The distribution of logistics efficiency is mainly "block" in space. In terms of spatial correlation, Global Moran's I was significantly positive from 2007 to 2017. The logistics efficiency of the provinces and cities in the Yangtze River Economic Belt showed a positive spatial correlation, and the provinces and cities with similar logistics efficiency were spatially clustered. However, the internal development is uneven, with a stepped distribution from east to west. At last, in order to promote the regional coordinated development of the logistics industry in the Yangtze River Economic Belt, the research proposes that it should continuously promote industrial transformation and upgrading, strengthen regional cooperation, improve infrastructure construction, increase the opening up of inland areas and establish large-scale logistics parks.
