基于多元统计方法的新疆固定资产投资结构分析

INVESTMENT STRUCTURE OF XINJIANG'S FIXED ASSETS BASED ON MULTIPLE STATISTICS

运用因子分析法对新疆15个地区14个行业的固定资产投资进行分析,提取出3个公因子(固定资产投资综合因子、服务性投资因子和高级产业投资因子)分析各地区的投资结构和产业布局。在此基础上,运用聚类分析法将15个地区分成5类,找出投资结构类似的地区。最后,利用3个公因子,对新疆各地区投资结构与经济增长之间的关系进行回归分析,结果表明固定资产投资综合因子对经济增长起正向拉动作用,而服务性投资因子和高级产业投资因子对经济的拉动作用是负向的,说明新疆的经济增长还是粗放型的,从而为今后新疆固定资产投资结构与产业布局的优化调整提供理论依据和方向参照。

This paper applies factor method to analyze the fixed assets investment in 14 sectors in Xinjiang＇s 15 areas, of which 3 common factors, fixed assets investment, service investment and advanced industry investment, are selected to study the investment structure and industrial layout in each area. Clustering analysis is applied to classify the 15 areas into 5 categories by their similar investment structure. The 3 common factors are used in regression analysis to find the relation between investment structure and economic growth, with result indicating a positive drive from fixed investment, but negative from service investment and advanced industry. It shows that Xinjiang＇s economy is primitive. This paper offers reference for Xinjiang to optimize and adjust the fixed assets investment and industrial structure.
