The purpose of this paper is to examine the effect of urbanization on infrastructure and
transportation in the level of provincial government expenditures by using the data of 76 provinces
across Thailand. Previous research has shown that one of tools that can affect on urban growth is the
urbanization level. In this paper, the model focuses on the formation of the endogenous function in
terms of aggregations of total provincial expenditures between infrastructure and transportation in
terms of per capita. The findings reveal the positive impact of urbanization on infrastructure provincial
government expenditures as well as transportation expenditures. In this paper, it also examines the
relationship between provincial expenditure growth and various exogenous variables that these can be
considered as sources of expenditure growth on infrastructure and transportation.
