摘要
使用Pearson相关性分析工业生产因素之间的关联性,采用数据包络分析方法对河南省工业生产效率进行分析.研究结果显示,河南省工业投入存在过剩现象;工业效率存在一定的周期性,而周期性产生的原因为投入的“滞后性”;工业就业人数对工业生产影响较大,能源投入和固定资产投入对工业产值的影响在逐渐降低,工业固定资产投入的增加会导致工业就业人数的增加,但其呈现边际递减规律;在DEA无效的年份中,工业固定资产投入调整值呈现上升趋势,工业就业人数调整值趋于平稳,工业能源投入调整值整体下降.
In this paper,Pearson correlation is used to analyze the correlation between industrial production factors,and data envelopment analysis is used to analyze industrial production efficiency in Henan Province.The results show that the industrial investment in Henan Province is surplus.The industrial efficiency of Henan Province has periodicity,and the reason of periodicity is the lag of investment.The number of industrial employment has a great impact on industrial production.The influence of energy input and fixed asset input on industrial output value is gradually decreasing.The increase of industrial fixed asset input will lead to the increase of industrial employment number,but it shows the law of marginal decline.In the year when DEA is ineffective,the adjusted value of industrial fixed asset input in Henan Province presents an upward trend,the adjusted value of industrial employment number tends to be stable,and the adjusted value of industrial energy input decreases as a whole.
