2. Internal resource waste in two-stage system
In this section, a system with a two-stage structure is described, in which the outputs from the first stage are used as the inputs for the second stage. It is essentially the same as the traditional two-stage system presented by Kao and Hwang [23] and Du et al. [17]. Here, we use the banking system in Seiford and Zhu [27] as an example shown in Figure 1 to illustrate the two-stage structure. *** [Insert Figure 1 about here] *** In this banking system with the above structure, the process from “employees,” “assets,” and “equity” to “revenue” and “profits” is defined as stage 1, and the process from “revenue” and “profits” to produce “market value,” “earnings per share,” and “returns to investors” is defined as stage 2. For ease of explanation, we assume that n DMUs with two-stage structures will be evaluated. We define the notations in the two-stage system as follows. X is the input of the production system, Y is the intermediate measure (i.e., the output of the first stage and the input of the second stage), and Z is the output of the production system. In other words, the first stage takes place when the supplier uses X to produce Y , while the second stage takes place when the manufacturer uses Y to produce Z . As we know, the output-oriented DEA model aims to find the maximum outputs for the system under the current inputs, and the input-oriented DEA model aims to find the minimum inputs for producing the current outputs of the system. In real companies, pursuing more output with limited resources are more common than reducing inputs while maintaining the level of outputs. With this in mind, we focus on building DEA output-oriented models for measuring IRW in a generic two-stage production system, where all outputs from the first stage become the inputs for the second stage. We also study the impact of the degree of centralization on IRW in a two-stage production system. By 8 measuring the quantitative relationship between degree of centralization and internal resource waste, managers can make more reasonable decisions on enhancing, maintaining, or decreasing centralization, based on their goals for reducing waste and their firms’ real ability to centralize.
