摘要
以多元统计理论为手段 ,以SAS软件为工具 ,在作系统的数据计算的基础上 ,对我国煤炭工业1988- 1997年 10年间技术进步状况进行了主成分分析 ,得出了一些有益的结论 ,提出了几个值得思考的问题 .作者试图通过这一研究 ,对煤炭工业综合技术进步的总体趋势作出科学的评价 ,并找出其主要的影响因素 ,为煤炭主管部门和煤炭企业制订加速技术进步的策略和措施提供理论指导的和参考依据 .
In this paper,with the theory of multivariate statistical analysis as a measure and the software SAS as a tool,the authors analyzed the technical progress in coal industry in the light of principal components during the 10 years from 1988 to 1997.By using systematic data counting,the authors reached several useful conclusions and put forward several questions that are worth being considered.By the study,the authors intend to evaluate the general direction of the technical progress in coal industry,and find out the main influential factors.It would provide academic instruction and reference basis for the coal department in charge and coal enterprises to map out the strategies and measures for accelerating the technical progress.
