美国高速公路融资结构变化的面板数据分析

Panel data analysis of highway financing structure change in USA

为确定高速公路融资及其结构的影响因素,建立了固定效应和随机效应模型,运用面板数据回归方法对美国50个州的平行数据进行检验,对高速公路融资结构与经济结构和人口结构之间的关系进行研究。研究结果表明:人均个人收入及人口密度对地方政府融资结构的影响显著高于对州级政府融资结构的影响,65%人口出资比例以及男性人口出资比例对州级政府融资结构的影响具有显著的时序效应,非公路使用者以及女性公路使用者的出资比例逐渐趋于平衡,这对中国经济转型时期的高速公路融资具有重要的现实意义和参考价值。

In order to determine the factors that affect highway financing, a fixed effect model and a random effect model were built, the parallel data of 50 states in USA were examined by panel data regression method, the relationships between expressway financing structure and economic structure ＆ population structure were analyzed. The result indicates that the influence of PGNP and population density on local government financing structure is more obvious than on state government, the subscribed capital proportions of 65% population and the male have significant time series effect on state government financing structure, the subscribed capital proportions of female users and highway non-users are gradually balanced. The study has practical significance and reference value to expressway financing during economic conversion period in China. 3 tabs, 8 refs.
