制度环境、产权性质与种植业产业链纵向整合——来自30家上市农业关联企业的证据

Institutional environment, property rights and vertical integration of planting industry chain: Evidence from 30 listed agricultural related enterprises

纵向整合有助于参与主体互补利益的实现与产业的可持续发展。基于30家上市农业关联企业2000—2015年的数据,测算了种植业产业链(种子企业、种植企业和农副食品加工企业)及其不同环节企业的纵向整合度,运用面板Tobit模型分析了制度环境和产权性质对种植业产业链纵向整合度的影响。结果表明:种植企业的纵向整合度最高,农副食品加工企业次之,种子企业最低;对于种植业产业链的纵向整合,制度环境有显著负向影响,产权性质有显著的正向影响;制度环境与产权性质对种子企业、农副食品加工企业都具有显著的负向影响,产权性质对种植企业具有显著正向影响,但是制度环境对种植企业的影响不显著。

Vertical integration helps the participants to realize the complementary interests and the sustainable development of the industry.Based on the data of 30 listed agricultural related enterprises from 2000 to 2015,the vertical integration degree of the planting industry chain(seed enterprises,planting enterprises,and agricultural and non-staple food processing enterprise)and their different links was calculated,and then the influence of institutional environment and property rights on the vertical integration was analyzed with the panel Tobit model.The results show that:The vertical integration degree of planting enterprises is the highest,followed by agricultural and non-staple food processing enterprises,and the seed enterprises the lowest.For the entire planting industry chain,the institutional environment has significant effect,and the property right has significant positive impact.Both the institutional environment and property rights have significant negative impact on seed companies and agricultural and non-staple food processing companies.Property rights variable has significant positive impact on planting enterprises,but the institutional environment has no significant effect on planting enterprises.
