China has one-sided emphasized economic development in the past several decades. But destruction of ecological environment caused by economic development becomes more and more serious in China, such as heavy fog in big cities around whole country in recent months. Nowadays more and more scholars realize that development of regional economy is not equivalent to the development of regional welfare, one-sided emphasized economic development run counter to regional welfare improvement in some Chinese regions now. Adopting the sectional data of 287 cities and spatial econometric analysis methods, this paper makes an empirical research on the factors which influence the spatial distribution variation of regional welfare. The result reveals that: the distribution of regional welfare is influenced significantly by the spatial structure variation of economy, society and ecology. Among the influence factors, regional market potential, consumption expenditure, regional Gini coefficient and carbon productivity strongly influence the spatial welfare. Based on theoretical and empirical analysis, several policy recommendations is proposed to enhance regional welfare.
