摘　　要：本文基于企业污染治理技术最优投资与社会计划者最优污染税率设计的研究问题,建立一个考虑知识积累时生产单一产品的垄断企业最优控制模型。研究表明:(1)在企业利润最大化和社会福利最大化条件下,控制系统都存在唯一的鞍点均衡;(2)在寡头企业决策和社会计划者决策的条件下,当两个控制系统均衡时,存在唯一的最优污染税率;(3)社会福利最大化条件下企业的污染治理投资和生产水平高于企业利润最大化条件下的污染治理投资和生产水平;(4)社会福利最大化条件下的污染累积和企业单位产品的污染排放量(即企业的污染治理技术)低于企业利润最大化条件下的污染累积企业单位产品的污染排放量。本研究丰富了考虑知识累积时企业污染治理技术创新行为的研究理论,对具有知识累积特征企业的创新管理具有现实指导意义。Due to the dual externalities of pollution control technology innovation,external environmental regulation is essential.Environmental regulations influence the attitude of enterprises towards the natural environment through coercion and inducement.By incentivizing enterprises to improve their innovation capabilities,offsetting the costs brought about by environmental protection,and enhancing their profitability in the market,domestic enterprises can gain a competitive advantage in the international market,thereby improving industrial productivity.Numerous studies have shown that under the influence of environmental regulations,enterprises will choose different investment decisions for pollution control,confirming the importance of the selection and design of environmental regulations.However,existing research has overlooked the issue of knowledge accumulation in the investment process of pollution control technology.Knowledge accumulation is caused by“learning by doing”in the investment process of pollution control technology.Knowledge accumulation is a by-product of the investment process,and“learning by doing”is an important way to improve production efficiency and achieve endogenous economic growth.This article applies the theory and methods of optimal dynamic control,based on the research problem of optimal investment in enterprise pollution control technology and optimal pollution tax rate design by social planners,to establish an optimal control model for monopolistic enterprises that consider knowledge accumulation in producing a single product.Compared with existing research,the problem of knowledge accumulation is considered in the investment process of enterprise pollution control technology.Based on the practical background,enterprises will transfer pollution taxes to consumers,and the consumer demand function is modified with pollution taxes.Then,the optimal investment and output level of enterprise pollution control technology under the conditions of maximizing enterprise profits and social w
