本文以西藏自治区经济增长为对象,依据1978—2010年的宏观经济数据,利用计量经济模型,对西藏固定资产投资与经济增长之间的关系进行实证分析。结果显示,与其他地区对比,说明西藏对固定资产投资的利用效率较低。通过Granger检验发现西藏的固定资产投资是经济增长的格兰杰原因,同时前期经济增长也是后期的投资增长的格兰杰原因。另外,经济增长受前期经济增长影响较为明显,前期经济增长的78%为后期经济增长构成的主要部分。
Based on the economic data of Tibet Autonomous Region from 1978 to 2010, this paper uses econometric model to analyze the relationship between investment in fixed assets and economic growth in Tibet Autonomous Region. The results show that, compared with other regions, it shows that Tibet is inefficient in using fixed-asset investment. Granger test found that investment in fixed assets in Tibet is the Granger reason for economic growth, while the previous economic growth is Granger reason for the latter part of investment growth. In addition, the economic growth is more obviously affected by the previous economic growth. 78% of the previous economic growth is the major part of the economic growth in the later period.
