A Study On Effect Of The Infrastructure For Investment To Economic Growth In Xinjiang Uyghur Autonomous Region

Since the implementation of development strategy for the western region in 1999,the economic growth in Xinjiang Uyghur Autonomous Region has witnessed significant achievement, particularly, the growing rate is double-digit from 2003. In this period, in addition to the effects of market economy (system) in economic growth, the investment policy for the infrastructure has also played a very important role. Therefore, research on the investment for the infrastructure in economic growth help government make the right policy, so as to promote economic growth and to narrow economic gap between the eastern and western regions. This paper analyzes total amount and structure of investment for infrastructure based on statistic data through an empirical analysis. Then, a panel data model is established according to the panel data from 2005 to 2009, and the relation between the investment for infrastructure and economic growth of Xinjiang Uyghur Autonomous Region is analyzed. The results show that, judging from the investment supply for infrastructure, the amount is insufficient. Except for gas, water production, investment for supply industry and education, the investment for other infrastructure industries is below the national average. And, particularly the investment of transportation, water conservancy and environment can't keep up with the fast growth of the economy in Xinjiang Uyghur Autonomous Region, which form obstacles for the economic growth; Judging from the structure of investment, the proportion of investment for infrastructure to that of investment for social fixed assets is not stable, internal structure of investment for infrastructure is unreasonable, paying much attention to the investment for productive infrastructure, and ignoring the role of the investment for social infrastructure; Judging from the effect of the investment for infrastructure in economic growth in Xinjiang Uyghur Autonomous Region, economic output elasticity of productive infrastructure, such as transportation, warehousing and postal service, power, gas and water production, is negative; on the contrary, the output elasticity of social infrastructure is positive. Actually, from the regional distribution of output coefficient of productive factors, the more developed the area is, the greater the contribution of the investment for infrastructure to economic growth.
