This paper examines how cities and regions within countries are likely to adjust to trade openness and improved connectivity driven by large transport investments from China's Belt and Road Initiative. The paper presents a quantitative economic geography model alongside spatially detailed information on the location of people, economic activity, and transport costs to international gateways in Central Asia to identify which places are likely to gain and which places are likely to lose. The findings are that urban hubs near border crossings will disproportionately gain while farther out regions with little comparative advantage will be relative losers. Complementary investments in domestic transport networks and trade facilitation are complementary policies and can help in spatially spreading the benefits. However, barriers to domestic labor mobility exacerbate spatial inequalities whilst dampening overall welfare.

This paper develops a computable spatial equilibrium model of Central Asia and uses it to analyze the possible effects of the Belt Road Initiative on the economy of the region. The model captures international and subnational economic units and their connectivity to each other and the rest of the world. Aggregate real income gains from the Belt Road Initiative range from less than 2 percent of regional income if adjustment mechanisms take the form of conventional Armington and monopolistic competition, to around 3 percent if there are localization economies of scale and labor mobility. In the latter case, there are sizeable geographical variations in impact, with some areas developing clusters of economic activity with income increases of as much as 12 percent and a doubling of local populations, while other areas stagnate or even decline.
