Benefits analysis for 12. 5 m deep-water channel second-phase project in the Yangtze River below Nanjing

为科学评价长江南京以下12.5m深水航道二期工程的实施效果,通过运输经济模型、投入产出法、重力模型等研究方法,全面分析工程的经济、社会、宏观、环境效益。结果表明,长江南京以下12.5m深水航道工程实施以来,已经取得了显著降低物流成本、带动区域经济增长、新增就业岗位、拉动财政收入增长、促进沿江地区节能减排等实际效益,工程的战略意义得到充分体现。

To scientifically evaluate the economic and social benefits of the 12.5-meter deep-water channel second-phase project below the Yangtze River below Nanjing,we analyze the economic benefit,macro-benefit,social benefit and environment benefit of the project by building a transportation economic model,an input-output model and a gravity model.The research reveals that significant benefits such as reducing logistics costs,driving regional economic growth,adding new jobs,stimulating fiscal revenue growth,and promoting energy conservation.Thus the strategic significance of the project is fully reflected.
