运用SORM-BCC超效率模型对中国餐饮旅游行业22家主要上市公司2002～2009年间的经营绩效及收敛趋势进行了评价和分析。研究结果显示:第一,静态来看,由于规模效率不高,使得综合技术效率普遍偏低;第二,动态来看,技术水平变化是TFP增长的强劲来源,然而,由于纯技术效率变化呈现明显衰退,影响了样本公司经营绩效的进一步提升;第三,餐饮旅游业的经营绩效及分解项存在一定的σ收敛趋势和不同程度的β绝对收敛趋势;第四,对于不存在β绝对收敛趋势的景点类上市公司的规模效率以及酒店类上市公司的综合技术(超)效率,借助自举法,认为两者都存在β条件收敛趋势。
Using the SORM-BCC super-efficiency model, the performance and convergence trend of 22 major listed companies in the Chinese restaurant and tourism industry from 2002 to 2009 were evaluated and analyzed. The results show that: First, from the static point of view, the efficiency of integrated technology is generally low because of the low efficiency of scale. Second, the dynamic change of technology level is a strong source of TFP growth. However, due to the change of pure technology efficiency The obvious recession has affected the further improvement of the operating performance of the sample companies; thirdly, there exists a certain degree of σ convergence trend and a certain degree of β absolute convergence trend in the operation performance and decomposition items of the catering tourism industry; fourthly, for the absence of β absolute convergence trend The scale efficiency of listed companies and the comprehensive technology (super) efficiency of hotel listed companies. With the help of bootstrapping method, it is considered that both of them have β conditional convergence trend.
