摘要
运用超效率DEA-Tobit模型对中国机械设备行业30家上市公司2002～2009年间的经营绩效及影响因素进行了分析,研究发现:纯技术效率和规模效率不高使得综合技术效率均值普遍偏低;技术水平变化是TFP增长的强劲来源,但规模效率的明显衰退影响了其进一步提升;公司资产周转率、人均资本均显著正向影响经营绩效,公司股权集中度也具有正向作用,但只有最大股东持股比例影响显著;公司上市年龄和规模都负向影响经营绩效,且只有前者的影响显著。
Using super efficiency DEA-Tobit model,this paper analyzes operational efficiency and the influencing factors of 30 major machinery equipment listed companies in the year of 2002-2009.Results show that： because neither pure tech-efficiency or scale efficiency performs well,average values of tech-efficiency are always low;tech-change is the major and strong source of TFP growth,however,because of obvious recession of scale efficiency change,further growth of TFP is restrained;asset turnover and capital per captia affect operational efficiencies of machinery equipment listed companies both positively and significantly,share concentration is also has positively effect,but not significantly except the largest shareholding ratio;listed age and scale both play negative roles,but only the former performs significantly.
