中国の高速道路網の建設と産業発展の実証分析

我进行了正在进行的关于交通基础设施影响评估的研究。研究的重点地区是中国的主要地区。我修改了两篇关于中国公路网影响评价的稿件（合作作品）。其中一份手稿最终被《区域科学论文集》（9月15日接受）接受。2015年8月8日）”，另一个正在“区域科学杂志”进行第三轮审查。2015年5月，我应邀在湖南大学（中国）就公路项目进行了演讲，并完成了关于日本经济和交通基础设施的影响的两篇论文（合作）。我受邀于2015年11月13日在波特兰（OR）举行的城市经济学协会年会上发表演讲。本研究是关于新干线建设对日本人口动态的影响评价。交通基础设施是与公共财政相关的非常重要的项目。一方面，这类基础设施的投资通常是巨大的，因此认真研究其社会回报对于平衡公共财政非常重要。另一方面，运输成本是货物生产/贸易（农产品和制造业产品）和人们日常成本（通勤成本、跨区域旅行成本）的关键要素成本，对交通基础设施的投资是提高社会生产力的良好途径。

I conducted the in-progress research on impact evaluation of transport infrastructure. The focus of study area is primary in China. I revised two manuscripts (joint work) on the impact evaluation of China's highway network. One of the manuscripts was finally accepted by "Papers in Regional Science (accepted on Sept. 8, 2015)" and another one is now under third round review at "Journal of Regional Science". In May 2015, I was invited to give a presentation at Hunan University (China) on my highway projects.In addition, I finished another two papers (joint work) on Japanese economy and the impact of transport infrastructure. And I am invited to give a presentation at Urban Economics Association Annual Meeting at Portland (OR) on November 13, 2015. The research is on the impact evaluation of Shinkansen construction on Japan's population dynamics.The transport infrastructure is a very important project related to public finance. On the one hand, the investment on such kinds of infrastructure is generally huge, thus a careful investigation of its social return is important to have a balanced public finance. On the other hand, transport cost is a key factor cost for both goods production/trade (agricultural and manufacturing goods) and people's daily costs (commute cost, cross-regional travel cost) , investment on transport infrastructure is a good way to improve social productivity.
