Dynamic Concept of Returns to Scales and Its Characteristics on production Frontier in Intersection Form

This paper gives a dynamic concept and a new non-parametric method for evaluating returns to scale（RTS） of economic units with multiple inputs and *** is frequently noticed that when we increase the input of a decision making unit（DMU） with a certain status of RTS,different status of RTS is *** example,when we increase the input of a DMU with constant RTS under the traditional method,a decreasing RTS is often observed instead of the expected constant *** thus define the RTS of each DMU in both input expansion and contraction regions *** research starts from transferring the production possibility set into the intersection form,by giving the explicit linear inequality representation of production *** RTS structural characteristics of DMUs＇ on the production frontier are *** of RTS of those DMUs on the production frontier include increasing RTS,constant RTS,decreasing RTS,saturated RTS and evidence of *** and suficient conditions for RTS evaluation are *** definition and evaluation method given here provide more detailed economic characteristics of DMU for policy makers.
