摘要

本文的目的是提出一個方法研究網路結構，認為網路結構包含兩個關鍵因素：連接物和中間產物。此外，我們將中間產物分為四種類型，即期望的，非期望的，可自由支配的，不可任意支配的。本文基於DEA-SBM方法研究網路結構，首先，將網路結構分為三個階段，其次，分別計算這三個階段的效率值，最後，集結三個階段的效率值，另外，基於該模型，本文利用2011年的焦炭產業鏈進行能源效率分析。

The purpose of this paper is to develop an approach to a network structure which considers the two factors: link, intermediate. Furthermore, we categorize intermediate activities into four types, i.e. desirable, undesirable, discretionary and nondiscretionary. We will analysis a decomposed network and integrated approach based on data envelopment analysis (DEA) on the basis of slack-based measure (SBM). Firstly, classifying the network structure into three stages; secondly, opening the black box to obtain the period efficiency; lastly, it allows us to integrate the efficiency value of a DMU at all stages. An example is used to be done for efficiency evaluation about coke production chain of twelve provinces of China.
