摘　　要：本文利用2009—2017年中国农村固定观察点微观入户数据,在广义罗伊模型框架下,估计了交通基础设施改善对农村劳动力外出务工的影响。研究发现,连通交通主干线增加了农民外出务工收入。进一步的研究表明农村交通基础设施改善对农民外出务工的影响存在根本的异质性,更容易连接交通主干线的农村地区,连接交通主干线对外出务工收入的影响是负的,而对于交通基础设施可及性越差的农村居民,连通交通主干线会显著增加他们的外出务工收入。通过对未来农村交通基础设施进一步改善的效应进行模拟,发现落后农村地区在连接交通主干线之后外出务工收入会明显增加。China's rural transportation infrastructure has achieved tremendous success,profoundly impacting agricultural development and the lifestyles of farmers.This paper utilizes the micro household data from the fixed observation points in China's rural areas from 2009 to 2017,and estimates the impact of improvements in transportation infrastructure on the outworking of rural labor within the framework of the generalized Roy model.The study finds that connectivity to the main traffic arteries increases the income of farmers working outside their hometowns.Further research indicates that there exists essential heterogeneity in the impact of rural transportation on farmers'outworking incomes.In rural areas that are more easily connected to the main traffic arteries,the impacts of such connectivity on outworking income is negative.However,for rural residents with poorer accessibility to transportation infrastructure,connecting to the main traffic arteries significantly increases their income from working outside their hometowns.By simulating the effects of further improvements in future rural transportation infrastructure,the study finds that the income from outworking will noticeably increase for residents of less developed rural areas after connecting to the main traffic arteries.This paper demonstrates that connecting to the main traffic arteries can significantly narrow the income gap between less developed rural areas and more developed regions,thus providing an academic support for the national initiative to achieve“access to all villages”in rural areas.
