摘要
从灰色关联模型入手,计算了2004-2009年天津市物流网络规模与区域经济的关联程度及协调度,表明物流网络规模各衡量指标与区域经济发展水平各衡量指标的关联程度存在差异,其中第一、二产业产值、外贸进出口总额和社会消费品零售总额与物流网络规模关联程度较大,物流节点企业数量、公路、铁路营业里程、货运量和货运周转量与区域经济发展水平关联度较大。物流网络规模与区域经济发展水平的协调程度存在时间演化趋势,从2004-2009年均处于协调程度不断增强的阶段。
Using gray correlation analysis, the paper calculates the degrees of correlation and coordination between the logistics network scale and local economic development of Tianjin within the time brackets of 2004 and 2009, the findings of which indicate that there indeed exist differences in the levels of correlation between the various measurement index of logistics network scale and those of the regional economic development. More specifically, there is greater correlation between logistics network scale and gross production of the first and second industries, foreign trade and export/import volumes, and gross social consumption while the same is true for regional economic development with quantity of logistics nodal enterprises, mileage of highway and railway operations, freight volume and freight turnover. The level of coordination between logistics network scale and regional economic development is subject to temporal evolution, which, in the case of this paper, is on an increasing steep curve for the whole duration between 2004 and 2009.
