One of the major reasons of privatization is that the private company is more efficient in carrying out economic activities and reducing the public debt. In Taiwan, Chinese Petroleum Corporation (CPC) will face some challenges and pressures of privatization policy and liberalization of oil industry. CPC must understand their differentiation from other competitors, and strive to improve their performance. It is the important subject to increase efficiency for CPC.
Therefore, with application of Data Envelopment Analysis (DEA) approach, this study conducts performance analysis among twenty-six reforming units. The input factors include three items; the output factors are seven items. While interacting the above factors and calculated by Frontier analysis, performance efficiency results for each reforming units are measured, including category of efficiency unit, the best inputs in each reforming units. A sensitive analysis has also been conducted to achieve more accuracy.
The findings of this study are as followings:
1. According to the efficiency analysis, the research finds all units waste their costs, so they should decrease the inputs or increase the productivity to make all units effective.
2. According to the scale efficiency analysis, it must improve the input, the ratio of the output, and adjust the scale of productivity to accomplish the efficiency. In addition, identify the most efficient unit as the model to help others to optimize management strategy and to maximize contribution.
3. According to the slack variables analysis, it suggests managers should improve the numbers of inputs and outputs.
4. According to the sensitivity analysis, it shows that CPC has persisted stability, and proving that the company is moving toward an efficient business.
Finally, some results and suggestions of the empirical study may provide some useful information to decision-makers of CPC and seek solutions of achieving higher managerial efficiency in the future.
