基于江苏、山西、四川三省数据，研究改革开放以来城镇居民消费结构的变化趋势与地区差异，发现中西部低收入地区边际消费倾向更高，而东部高收入地区更低，导致全国有效需求不足。
Promoting economic growth through investment will not be sustainable in resent years,so expanding domestic demand and adjusting the relations between investment and consumption are urgent needs to implement the economic restructuring.Based on data drawn from three typical provinces-Jiangsu,Shanxi and Sichuan,this paper focuses on their differences and similarities,as well as change trend of their urban citizen's consumption structure.We draw a conclusion that Middle and Western region with lower income has higher MPC,while Eastern region with higher income has lower MPC,which cause the insufficiency of effective demands of the whole country.Our suggestion is to narrow the gap of districts and increase the expenditure rate of citizens,especially those in eastern district.
