本文采用2000～2009年我国省际面板数据，通过建立基于外商直接投资对经济发展影响的居民 相对消费水平双门槛模型，证实了当居民相对消费水平位于第一与第二门槛之间时，FDI对 经济的推动作用最为显著。东部沿海地区大多属于低相对消费水平区域，在未来经济发展中，需将投资主导型的经济增长方式转变为消费主导型，提高FDI对经济增长的正向影响作用；中西部地区表现为消费主导型的经济增长方式，应该进一步的招商引资，提高FDI的投入水平，实现其对经济的拉动作用。

he purpose of doing research on the effect of FDI on economy in different consum
e level,this paper establishes the threshold model to confirm the existence of o
penness threshold effects by using China provincial panel data from year 2000 to
2009.The result showed that double threshold effect of FDI on economic growth e
xists,and FDI boosts the economy most significantly when the opening degree betw
een the first and second threshold.Most provinces in eastern of China are in low
er consumer level.In order to improve the positive impression of FDI to economy
