文章基于C—D生产函数的Solow模型，通过计量方法得到我国东、中、西部三大地区的生产函数，进而计算出固定资本存量（K）、劳动（L）、全要李生产率（TEP）对经济增长的贡献率。结合三大地区经济增长趋势的变化得出，三大地区经济差距主要是由投资的差距引起的。因此，要缩小东、中、西部的经济差距，必须加大对中西部的投资，加大对西部地区的科技投资。

This paper made use of the economic data, according to the Cobb--Douglas production function, and got the production functions. The contribution rates of the capital, labor and total factor production were calculated according to the model results. We got that the economic disparities of three belts were caused by the differences of investments in these areas. As a result,the government must invest more capital to the central and western belts to reduce the disparities of these three areas, especially more in science and technology.
