大气污染与环境规制对企业库存的影响机制研究——基于广东省工业企业数据

Mechanism of How Air Pollution Control and Environmental Regulation Influence Enterprises’Inventory:Based on the Data of Industrial Enterprises in Guangdong Province

本文从系统学视角出发,构建了大气污染与环境规制对工业企业库存产生效用的系统动力学模型,研究减排政策、工业污染治理投资、交通基础设施投资以及科技投资的变化对广东省工业企业库存和工业经济的影响效应。仿真结果表明:实施减排政策及加大工业污染治理投资均可减缓工业企业的库存压力,且两个政策的同时实施对库存压力的减缓作用产生了"1+1>2"的协同效应;加大交通基础设施投资和科技投资均会使工业企业库存压力有所减缓;随着这些政策实施年限的增加及力度的加大,对库存压力的减缓作用越来越强,给工业经济带来的正效应也逐渐增大。最后根据仿真结果,为从环境规制和投资政策的角度降低工业企业库存,促进工业经济发展提出相关政策建议。

From the perspective of systematics,we construct a system dynamics model of the effect that air pollution control and environmental regulation have on industrial enterprises’inventory,and study how the industrial enterprises’inventory and industrial economy in Guangdong Province are influened by changes in policies regarding emission reduction,industrial pollution control investment,transportation infrastructure investment and scientific&technological investment.The simulation results show that either emission reduction policy or industrial pollution control investment promotion policy can alleviate the inventory pressure faced by industrial enterprises,and a synergistic effect of“1+1>2”on inventory pressure can be produced if both policies are implemented simulaneously.Transportation infrastructure investment promotion policy and technology investment promotion policy can also alleviate the inventory pressure faced by industrial enterprises.As these policies last and strengthen,they will become better able to alleviate inventory pressure and contribute more positively to industrial economy.Finally,according to the simulation results,relevant policy recommendations are proposed to reduce the inventory of industrial enterprises and promote the development of industrial economy from the perspective of environmental regulation and investment policies.
