【摘要】：自从改革开放以来，我国经济得到迅速发展。2012年我国国内生产总值GDP为518942.1亿元，在全球新增加的国内生产总值份额中所占比重达到20%，成为全球第二大经济主体。但是，在我国经济得到迅速发展的同时，各地区的人均收入水平差异也在不断加大。根据国家统计局公布的关于收入基尼系数的历史数据显示，2003年我国收入基尼系数是0.479，2004年是0.473，之后一直上升到2008年的0.491，随后基尼系数回落一直降到2013年的0.473。这也是继2009年基尼系数连续五年在下降，也是近十年来的最低值。但是我国基尼系数仍超出了国际公布的收入差距的警戒线0.4。人均收入差距也成为各界人士、学者关注的话题。根据经济增长理论和世界经济的发展实践，投资在经济增长中起到举足轻重的作用。在中国，促进经济发展“三驾马车”中投资是其中一个主要因素，成为近几年国家促进经济进一步增长所常用的政策方法。如果投资的数量差异可以使得收入差距加大，，那么考察我国投资与收入增长的区域差异现状，探寻投资对我国收入增长的作用机制差异，测度区域收入收敛性中投资的贡献大小，将对各地区依靠投资路径缩小区域收入差距提供理论借鉴和决策依据，这是本论文的研究出发点。论文在梳理国内外研究现状同时采用新古典经济模型中的索洛模型，从理论上剖析了收入收敛性。本文选取了2001-2012年的全国30个地区(除西藏)的数据考察了我国城镇人均收入的增长情况，在这12年，我国城镇人均实际收入从2001年6811.92元增长到2012的18766元，平均年人均收入增长速度达到9.65%。我国城镇人均收入增长的同时地区之间的差异较为显著，东部地区收入增长明显高于中部地区和西部地区，不仅如此，各地区省份之间也存在一定的收入差距。同时利用数据对我国城镇人均年收入差距的现状进行分析，得到如下结论： 1.研究期间内，在不加入任何影响因素下，我国城镇居民人均收入存在收敛，东部地区对缩小我国城镇人均收入差距的贡献较大，其次是中部地区，且东部地区人均收入收敛速度中部地区人均收入收敛速度，西部地区不存在收入收敛。2.加入固定资产投资率后，从整体来看我国城镇人均收入收敛效果明显，投资率进一步促进了我国人均收入收敛。3.分地区来看，加入固定资产投资率因素后，西部地区人均收入在投资率作用下由原来的不收敛变为现在的收敛状态，可见对我国西部地区进行投资促进了城镇人均收入增加，同时可以缩小城镇人均收入差距。东部地区和中部地区在投资的作用下人均收入差距也得到进一步缩小。
[Abstract]:Since the reform and opening up, China's economy has been developing rapidly. In 2012, the GDP of our country was fifty-one trillion eight hundred and ninety-four billion two hundred and ten million yuan, accounting for 20% of the new increase in the share of global gross domestic product (GDP), becoming the second largest economic main body in the world. However, while our economy is developing rapidly, According to the historical data on the income Gini coefficient released by the National Bureau of Statistics, the income Gini coefficient in China was 0.479 in 2003, 0.473 in 2004, and then rose to 0.491 in 2008. Then the Gini coefficient fell to 0.473 on 2013. This is the fifth consecutive decline in the Gini coefficient since 2009. But the Gini coefficient of our country is still beyond the warning line of international income gap 0.4. the income per capita income gap has also become a topic of concern for scholars and people from all walks of life. According to the theory of economic growth and the development practice of the world economy, investment plays an important role in economic growth. In China, investment is one of the main factors in promoting the "troika" of economic development. It has become a common policy method for the country to promote further economic growth in recent years. If the difference in the amount of investment can increase the income gap, then examine the current situation of regional differences between investment and income growth in China. Exploring the difference of mechanism between investment and income growth in China and measuring the contribution of investment in regional income convergence will provide theoretical reference and decision basis for regions to rely on investment path to reduce regional income gap. This is the starting point of this paper. At the same time, the paper adopts the Solow model in the neoclassical economic model. In this paper, the income convergence is analyzed theoretically. The data of 30 regions (excluding Tibet) from 2001 to 2012 are selected to investigate the growth of urban per capita income in China. The real per capita income of cities and towns in China increased from 6811.92 yuan in 2001 to 18766 yuan in 2012, and the average annual per capita income growth rate reached 9.65 yuan. The income growth in the eastern region is obviously higher than that in the central region and the western region, and there is also a certain income gap among the provinces. At the same time, using the data to analyze the current situation of the income gap of urban per capita income in China, the following conclusions are obtained:. 1. During the study period, without adding any influence factors, the per capita income of urban residents in China converged, and the contribution of the eastern region to narrowing the gap between urban per capita income of our country was greater, followed by the central region. The convergence rate of per capita income in the central region and the western region does not exist. 2. After the fixed asset investment rate is added, the convergence effect of urban per capita income in China is obvious from the overall point of view. The investment rate has further promoted the convergence of per capita income in China .3. by region, after adding the factor of investment rate in fixed assets, the per capita income in the western region has changed from the original non-convergence to the current convergent state under the action of the investment rate. It can be seen that investment in the western region of China promotes the increase of per capita income in cities and towns, at the same time, it can narrow the gap between per capita income of cities and towns, and the gap of income per capita between eastern and central regions is further narrowed under the influence of investment.
