【摘要】 传统技术效率估计方法使用的分析指标——资金K、劳动力L和产出Y,识别不出资产技术的差异,部分文献采用资金装备率k(或加职工人数L)和劳动生产率y来估计企业技术效率,本文探讨这一指标体系下的非参数技术效率分析方法,将传统(K,L,Y)空间的规模不变生产可能集映射到(k,y)空间,得到(k,y)空间的规模非增生产可能集.在(k,y)空间内,不仅可以计算决策单元在传统(K,L,Y)空间的规模不变技术效率,而且可以得到资产物理技术的最佳近似值-资产运营前沿技术.更多还原

【Abstract】 Conventional efficiency analyzing indexes,capital K,labor Land output Y,can’t identify embodied technology,some literature adopts labor productivity yand capital-labor ratio k(or plus labor L) in efficiency analysis.This paper explores the nonparametric approach under these indexes.The conventional constant returns to scale(RTS) production technology in(K,L,Y)space is projected into(k,y),here a non-increasing RTS production technology is obtained,by which conventional C2R technical efficiency can be easily estimated,also assets physical technology can be approached in(k,y)space,which is called assets operating-frontier technology.更多还原
