以1990-2012年统计数据为依据,使用stata的corr方法研究伊金霍洛旗GDP与煤炭开发的关系。结果表明:煤炭开发对伊金霍洛旗的经济发展贡献巨大;定量分析表明,两者关联度逐年增长;2012年达到0.9872,GDP煤炭的消费弹性和生产弹性分别为-13.38-2.02479,-9.19703-1.26132;煤炭消费量是导致GDP快速上涨的关键因素。采用主成分分析方法,由社会经济指标、城乡人口构成指标等构建多维组合矩阵,通过主成分估计得出,第一主成分中原煤产量的相关系数最高为0.9967,依据主成分载荷分析,即为Y ij与B J的相关系数,分析出未来该地区在发展中需要调配产业结构,提升原煤利用率。据此,为实现该地区中长期的经济效益、社会效益、生态效益平衡发展提供科学的依据。
Based on the statistical data from 1990 to 2012, the corr method using stata was used to study the relationship between the GDP of Yijinhuoluo County and coal development. The results show that coal development contributes a lot to the economic development of Yijinhuoluo County. The quantitative analysis shows that the correlation between the two is increasing year by year, reaching 0.9872 in 2012, the consumption elasticity and production elasticity of GDP coal are -13.38-2.02479 and -9.19703 respectively -1.26132; Coal consumption is the key factor leading to rapid GDP growth. Principal component analysis method is used to construct multidimensional combination matrixes from socio-economic indicators and urban-rural population composition indexes. The principal component estimates show that the correlation coefficient of raw coal yield in the first principal component is 0.9967. According to the principal component load analysis, Y ij and BJ correlation coefficient analysis of the future development of the region need to deploy industrial structure and improve the utilization of raw coal. Accordingly, a scientific basis will be provided for the realization of a balanced development of the long-term economic benefits, social benefits and ecological benefits of the region.
