Study On The Effect Of Fixed Assets Investment On Regional Economic Disparities

China’s economic reform and opening up has maintained rapid growth for30years that has created a development miracle. At the same time with the rapid growth of GDP, difference in regional economic performances increasingly evident. Shandong Province as the country’s major economic province also has the problem of the rapid economic development and regional economic disparities continue to increase. Therefore, how to effectively solve the regional economic disparities of Shandong Province is important to achieve balanced economic coordinated development of sustained, rapid and healthy development of the future economy of Shandong Province.Prior to study regional economic disparities increase countermeasures we must analyze the reasons that cause regional economic differences. Investment, consumption, import and export trade and said the Troika of the national economic growth, economic growth and plays an important role. As the most important investment in fixed assets investment, at the same time play a role in promoting economic growth has also become an important factor in regional economic differences increase.In this paper, we use Theil index and Gini coefficient method for quantitative analysis and study of regional economic disparities in Shandong Province. As can be seen by our analysis, Shandong Province, eastern and western regions of the overall economic differences in the past30years was constantly increasing trend. The eastern and western regions of the differences within the region is becoming smaller, but the difference between the east and west regions is becoming bigger. Differences within the region of the contribution rate of the Gini coefficient is small and declining, while the inter-regional differences in the contribution rate of the Gini coefficient larger upward trend.After unit root testing the Gini coefficient, the efficiency of investment in fixed assets, investment growth rate and determining the optimal lag order, construct a vector auto regression model. From regressing model, draw the conclusion that the correlation fixed asset investment efficiency of eastern and western regions of Shandong Province and the Gini coefficients is negative correlation; positive correlation between the Gini coefficients for the growth rate of investment in fixed assets. This shows that the fixed assets investment of eastern and western regions in poor efficiency increase that the Gini coefficient reduce, fixed investment growth rate to increase so that the Gini coefficient increased.From the econometric analysis above, we can further analyze the mechanism of the impact of the investment in fixed assets of the regional economic disparities, and further make relevant policy recommendations, guidance Shandong Province, fixed asset investment strategy to achieve balanced economic development.
