Abstract:

The disparity of regional economic development is a kind of impersonal phenomenon existing in economy and society.Appropriate disparity can promote the development of macroeconomy; however,great disparity is harmful for the development of regional economy,and even can affect the stability and sustainable development of the society.Since the 1990s，Hunan Province，one of the main agricultural provinces in China，has developed very rapid with the increase of economic aggregate and the strengthening of regional competitiveness.Whereas，the disparity of regional economic development has also become more and more obvious，needing to be paid great attention.Based on statistical economic data of Hunan Province in recent years,and through calculation of statistical parameters and variation coefficients,the general characteristics of temporal changes of regional economic development in the Province were analyzed.And by adopting factor analysis method and based on the establishment of integrated evaluation index system,the spatial pattern and its variation process of Hunan Province were also discussed.Based on the above analysis，it was indicated that the causes of disparities mostly consisted in differences of physical environments and locations,social culture，science and technology and education,historical and economic bases，policies and investment directions，and so on.Finally，the authors put forward some countermeasures to control the regional economic disparities and promote the harmonious development of different regions.
