摘要：This study uses the DEA (Data Envelopment Analysis) method to investigate the efficiencies of private RPCs (Rice Processing Center) and cooperative RPCs. Using the results of DEA and the government RPC evaluation scores, the study analyzes elements that affect the efficiencies of RPCs as well as the government evaluation scores in both single output cases and multiple output cases by regression methods. Unlike other previous studies, taking advantage of panel data, the study measures two different fixed effects (within effects and between effects) and random effects of the elements at the same time.
