摘　　要：中国西南内陆直通印度洋的西南陆海新通道建设成为“一带一路”合拢、西南地区“向海开放”的重大工程。构建三国四地区的新经济地理学自由资本模型,在传统东部出海贸易通道、新通道开辟、新通道高水平联通3种情景以及辅之于向西转移的产业补贴政策和促进西部与东部联通的交通基础设施投资政策两种情形下,模拟分析西南陆海新通道建设的空间经济效应,结果发现:(1)传统东部出海贸易通道下,中国深化开放政策有利于工业生产向拥有大市场的东部地区转移,但这将进一步扩大东西部差距;(2)西南陆海新通道开辟后,中国西部内陆直接从印度洋出海,贸易成本下降、贸易和市场规模扩大,本地市场效应促进工业生产向西部地区集聚,将缩小东西部差距;(3)新通道高水平联通下,四地区间产业资本布局竞争更激烈,中国西部地区与印度洋周边地区的通道效应最直接,可以很大程度上扭转其区位劣势;(4)与辅之于向西转移的产业补贴政策相比,促进西部与东部联通的交通基础设施投资政策具有内生的产业转移效应,或可助力破解“胡焕庸难题”。The construction of the New Southwest Land-Sea Corridor directly connecting the southwest inland with the Indian Ocean has become a major project of the “Belt and Road” and the “opening up” of the southwest region to the sea.By constructing the new economic geography model of the three countries and four regions:the footloose capital model,this paper simulates five scenarios in the traditional eastern sea trade corridor,the opening of the new corridor,the high-level connectivity of the new corridor,the industrial subsidy policy supplemented by the transfer to the west,and the transport infrastructure investment policy promoting the connection between the west and the east.The results show that:(1) Under the traditional east sea trade corridor,deepening the opening policy of China is conducive to the industrial production shift to the large market in the east region,but this will further widen the gap between east and west;(2) After the opening of the New Southwest Land-Sea Corridor,the western inland of China will directly go to sea from the Indian Ocean.The trade cost will decrease,the trade and market scale will expand,and the local market effect will promote the industrial production to the west,which will narrow the gap between east and west.(3) Under the high-level connectivity of the new corridor,the competition for industrial capital distribution among the four regions is more intense.The channel effect between the western region and the Indian Ocean surrounding region is the most direct,and it can reverse its location disadvantage to a great extent.(4) Compared with the industrial subsidy policy assisted by the westward transfer,the transport infrastructure investment policy that promotes the connectivity of the western and eastern regions has an endogenous industrial transfer effect,which may help solve the “Hu Huanyong problem”.
