我国上市农产品加工企业经营效率及影响因素分析

为研究我国农产品加工企业经营效率及其影响因素,运用C2 R模型、BC2模型、Malmquist指数法及Tobit模型对2011—2015年我国29家具有代表性的上市农产品加工企业进行研究。测算结果表明,我国上市农产品加工企业经营效率并不稳定,经营效率最低值为0.799,企业间经营效率差距较大;从效率变化均值来看,技术效率下降了1.2%,而技术水平和全要素生产率分别出现了6.9%和5.6%的增长幅度,技术水平变化是全要素生产率变化的主要原因,纯技术效率变化和规模效率变化不稳定,导致综合技术效率变化不稳定,最终影响了全要素生产率;回归结果显示,总资产周转率、企业规模、技术人员占比与企业经营效率及分解项之间呈正相关关系,而股权集中度和企业年龄与企业经营效率及分解项之间无显著相关关系。

Analysis of the operating efficiency and influencing factors of listed agricultural products processing companies in China

In Order to investigate the operating efficiency and influencing factors of some listed agricultural products processing companies in China,Malmquist of C²R,BC²,DEA and Tobit models were used to study 29 major listed agricultural companies from 2011 to 2015.The results showed that the operating efficiency of the listed agricultural products processing companies in China was not stable,the lowest was 0.799,and the operating efficiency gap between the companies was large.In terms of the average of efficiency change,technical efficiency was decreased by 1.2%,and the technical level and total factor productivity was increased by 6.9% and 5.6%,respectively.Technology change was the main cause of the total factor productivity change.Pure technical efficiency and scale efficiency changes were not stable resulted inthe unstable of comprehensive technical efficiency change and affecting the total factor productivity ultimately.And the DEA-Tobit regression results showed that the total asset turnover,company scale,and technical staff were correlated with the company operating efficiency positively,and there was no significant correlation relationship between the decomposition of operating efficiency with the concentration of ownership and the age of companies.
