摘要
本文将交通基础设施对产品的运输成本、生产要素的流动成本及土地租金等空间成本的影响整合到新经济地理学模型的理论框架之中。分析显示,当农村人口所占比重较大时,改善交通基础设施能促进生产要素流动并缩小要素在城乡之间的收入差距,但随着生产要素不断地向城市集聚,改善交通基础设施对生产要素流动性的影响不再显著,当集聚到城市的生产要素增至某一临界值时,生产要素在城乡之间的收入差距则呈现出反向扩大的趋势。
By integrating space cost of factors from transportation infrastructure, such as transport cost, factor mobility cost and land rental cost, into the classic model of new economic geography, this paper finds that the transport cost of industrial products has a positive impact on urban-rural income gap of factors while the transport cost of agricultural products is reversely associated with the income gap. Improved transportation infrastructure would slow down the agglomeration of factors towards central city and narrow down the urban-rural gap when the proportion of rural population is larger than it is in the urban. However, this effect tends less significant more and more factors wave into the urban, and the urban-rural income gap will even widen reversely when factors in the urban accumulate to a critical point.
