摘要
作为产业龙头企业和资本市场的参与主体,农业上市公司在促进乡村振兴中发挥着重要作用。为评价近年来农业上市公司经营效率的变化趋势、厘清效率有效提升的因果逻辑关系,运用DEA-BCC模型及Malmquist指数模型对2012—2019年我国农业上市公司的经营效率进行测度,并利用Tobit模型分析了经营效率的影响因素。静态来看,公司间、细分行业间效率值差异较大且整体呈下降趋势,其中纯技术效率低下是主要原因。动态来看,虽然技术效率下降,但行业技术进步使全要素生产率整体仍呈上升趋势。相较于其他细分行业,畜牧业表现出更好的发展态势,林业效率水平相对落后,纯技术效率与规模效率降幅均较大,动态来看,渔业行业技术水平变化指数普遍低于平均水平。影响因素方面,规模大、债务资本比重高对农业上市公司经营效率会产生负面影响,而较高的股权集中度会促进其经营效率的提升。
As the leading enterprises in the industry and the main participants in the capital market,agricultural listed companies play an important role in promoting rural revitalization.In order to evaluate the change trend of the operating efficiency of agricultural listed companies in recent years and clarify the causal logic relationship of effective efficiency improvement,DEA-BCC model and Malmquist index model are used to measure the operating efficiency of agricultural listed companies in China from 2012 to 2019,and Tobit model is used to analyze the influencing factors of operating efficiency.Statically speaking,the efficiency values between companies and between sub industries are quite different,and the overall trend is downward.The main reason is the low pure technical efficiency.From a dynamic perspective,although the technical efficiency has declined,the overall total factor productivity is still on the rise due to the technological progress of the industry.Compared with other subdivided industries,animal husbandry shows a better development trend,forestry efficiency level is relatively backward,pure technical efficiency and scale efficiency decrease greatly,and in a dynamic perspective,the change index of technical level in fishery industry is generally lower than the average level.In terms of influencing factors,large scale and high proportion of debt capital will have a negative impact on the operating efficiency of agricultural listed companies,while higher equity concentration will promote their operating efficiency.
