摘要
以十三家渔业上市公司的规模经济效应为主要研究对象,运用柯布-道格拉斯生产函数模型检验渔业企业所处的规模经济阶段,同时运用数据包络分析模型分析渔业企业的规模经济系数。结果表明,我国渔业企业整体处于规模报酬递减阶段,大多数企业处于非DEA有效状态。建议适当降低劳动力投入比例,加大相关研发投入力度,提高对规模经济效应的认识,充分发挥资本对企业生产经营的积极影响。
This paper focused on the scale economy effects of 13 Chinese listed fishery enterprises and firstly verified the scale economy effects stage of listed fishery enterprises with the model of Cobb-Douglas production function, then did research into the coefficient of scale economy of Chinese listed fishery enterprises with the model of data envelopment analysis. The results showed that： Chinese fishery enterprises as a whole were at the decreasing stage of the scale return and most of the enterprises were at the stage of non-DEA efficient. The proposals are reducing the labor input properly; increasing the intensity of relative research inputs; enhancing the understanding of scale economy effects and giving the capital of a positive impact full play to the enterprises＇ production and operation.
