利用網路資料包絡分析之電子遊戲產業效率研究

Efficiency Evaluation of Digital Game Industry by Network Data Envelopment Analysis

隨著軟硬體技術的成熟及網際網路的普及，電子遊戲產業正蓬勃發展，如何有效評估遊戲廠商的績效成了重要的課題。本論文建構一個適用於電子遊戲產業的網路資料包絡分析模型，選出20家電子遊戲廠商進行績效評估，將廠商的內部中間效率與整體效率視作不同的目標方程式，使用多目標規劃法求解各部門效率及整體效率，並將網路資料包絡分析與傳統資料包絡分析效率結果進行比較。本論文最後觀察各部門效率及整體效率的相關性，並以常用的財務比率與效率結果進行相關性分析，供決策者做參考。

With the maturity of software and hardware technology and the popularity of the Internet, the digital game industry has been booming. How to effectively evaluate the performance of game companies has been an important issue. This research constructs a network data envelopment analysis (NDEA) model for the digital game industry, and conducts the case study with 20 video game companies to evaluate the performance. The departmental efficiency and overall efficiency of the company are regarded as different objective functions in the multi-objective programing model. This method can calculate the efficiency of the firm and each department. Besides, this work observes the correlation between efficiency with nations and financial ratios. The results are expected to provide meaningful insight to the industrial decision makers.
