我国高铁发展的大都市经济圈溢出效应测度

The Measurement of Spillover Effect of Metropolis Economic Circle of China's High-Speed Railway Development

论文使用高铁带来的两地之间双向交通成本的变化测量大都市经济圈的引力强度和空间范围。结果表明地区产出对市场潜力的弹性为23.8%。旅行时间每27分钟大都市圈溢出效应减少50%,150分钟以后减少到1%。分行业分析表明高铁开通对不同部门影响大小是不同的。

This article uses the changes in the cost of two-way traffic caused by high-speed railway to measure the gravitational strength and space of metropolis economic circle. The results show that the resilience of regional output to market potential is 23.8%, every 27 minutes of travel time, the spillover effect of metropolitan circles is reduced 50%, and after 150 minutes, it reduces to 1%. The industry classified analysis show that the operation of high-speed railwayhas different effects on different department.
