对技术引进和经济规模有效性的分析

ANALYSIS ON TECHNOLOGY ACQUISITION AND THE EFFICIENCY OF ECONOMIC SCALE

采用数据包络分析法（ＤａｔａＥｎｖｅｌｏｐｍｅｎｔＡｎａｌｙｓｉｓ，ＤＥＡ法）对技术引进有效性及经济规模有效性进行评价，其参数选择原则为绝对数系列．以轴承行业５０家企业的数据，对同一时间点的现有生产要素配置条件下的企业经济规模有效性进行横向评价，以某厂８年数据对不同时间点企业技术引进的后期效果进行技术引进有效性纵向评价．

Using Data Envelopment Analysis (DEA) method to estimate the efficiency of technology acquisition and. the efficiency of economic scale. The principal of parameters selection is based on absolute numeric series. Two case studies are presented in this paper:one is based on the data of fifty bearing companies,a horizontal estimation of efficiency of economic scale of those companies is made according to the current production configuration data of the same time point;another one is based on eight years data of one company to do a vertical estimation of the post efficiency of technical acquisition on different time points.
