It is generally believed that privatization can effectively improve the performance of state-owned enterprises. However, some scholars found unsupportive outcomes, especially for the studies of Latin American and transition countries. This study applied the two-stage data envelopment analysis (DEA) procedure proposed by Simar and Wilson (2007) to analyze the performance of 100 operating branches of Taiwan Tobacco and Liquor Corporation owned by Ministry of Finance in order to offer another consideration other than privatization. Empirical results showed that on average, these branches could increase their efficiencies by 26.53 percent if all branches operate on the efficiency frontier; in addition, it can approximately increase the technical efficiency by 2.1 percent to 14.9 percent if a branch owns the business office and/or warehouse instead of renting it.
