摘要
根据1978-2011 年我国第三产业产值构成数据表,运用主成分分析的方法,采用数学降维的思想研究影响中国第三产业发展快慢的显著因素,确定影响第三产业发展的主成分,计算各个主成分的得分.进而根据最优回归模型对中国第三产业的发展趋势进行预测,最后对如何保持我国第三产业稳步发展给出合理化建议.
According to the data table of output value of China＇s tertiary industry from 1978 to 2011, this paper analyzes thesignificant impact factors influencing the speed of the development in China＇s tertiary industry through the analysis of the prin-cipal component and the reduction dimension of mathematics so as to determine the main ingredients influencing the develop-ment of the tertiary industry and to calculate the comprehensive score of each principal component. Based on the optimal re-gression model, this paper further forecasts the developing trend of China＇s tertiary industry. In the end, some reasonable adviceis given for keeping the steady progress of China＇s tertiary industry.
