摘　　要：从区域产业特性与货运需求的内在联系出发,探寻区域产业特性与区域货物运输需求变动间的规律,并以此建立数学模型,利用SPSS软件进行实证数理分析。结果表明,区域货运需求可以用第二产业规模、结构、集中度指标作为解释变量反映,货运需求与第二产业规模、集中度成正比例关系变动,货运需求与第二产业结构比重成反比例关系变动。From the regional industrial characteristics and interrelationship of demand of freight transportation, this paper tries to seek the law of relationship between the demand of regional freight transportation and regional industrial characteristics. And the paper then establishes a mathematical model and uses the software of SPSS to conduct analysis. The results show the indexes of the scale of secondary industry in the region and its structural, concentration degree can be used to explain it. It also shows that the freight transportation demand is in the direct proportion with the concentration degree and scale of secondary industry to change, but in inverse proportion with the structural proportion of secondary industry.
