ABSTRACT

This study estimates a regional production function for 16 regions in the period 1998~2010 to investigate spatial spillover effects of SOC. Various spatial scopes are analyzed in this study according to geographical distance, economic linkage and regional similarities in per capita income, industrial structure and population density. The main findings are as follows. Firstly, it is found that the SOC for transportation has a positive spillover effect on output growth in other regions as whole, however, the non-transporting SOC has a negative spillover effect. Secondly, as transportation capitals are divided into roads and the others like railways, airports and sea ports, the spillover effect of roads turns up negative on the neighboring regions and the regions in the same Economic Region. On the contrary, the other transporting SOCs are found to contribute positively to the economic growth of those regions. Thirdly, road SOC produces a positive spillover effect but the rest of transporting SOCs produce a negative spillover effect on the non-neighboring regions and the regions in the different Economic Region. These empirical findings provide some of implications to the central and local governments under a substantial pressure on fiscal restructuring. Among others, a careful consideration of spatial spillover effects of SOC investment are necessary to improve the investment efficiency when the governments make decisions on the locations and types of SOC investments.
