Dynamic Relationship Between Technology Innovation of Industrial Enterprises and Environmental Pollution: A Case Study of Zhejiang Province, China

摘要

Industrial enterprises are rising in China, but their backward technological level, poor independent innovation capability, excess production capacity, and low utilization efficiency of resources and energy have resulted in serious environmental pollution. The overall technology innovation efficiency of industrial enterprises in China can be effectively improved to reduce the industrial “three-waste”discharge but only when the enterprises promote structural optimization and adjust themselves toward industrial services through technology innovation. The influence of R&D expenditures of large- and medium-sized industrial enterprises on industrial “three-waste” discharge was estimated based on the panel data of 11 prefecture-level cities in Zhejiang Province during 2005 2016. In addition, technology innovation measures for environmental pollution control of industrial enterprises were proposed. The results demonstrated that enterprise technology innovation has an environmental protection effect, and improved enterprise production efficiency contributes to the reduction of pollutant discharge.Besides, enterprise R&D expenditures in most cities in Zhejiang Province are negatively correlated with environmental pollutant discharge, and the influence is significant. Moreover, the technology innovation input of industrial enterprises can reduce industrial pollutant discharge in Hangzhou, Ningbo, Wenzhou, Huzhou, and Taizhou due to their good economic foundations. The study results in this paper have a direct and realistic significance in analysing the influence mechanism for the technologyinnovation of ecological environmental pollution of enterprises, promoting optimization and upgrading of industrial structures in different regions, and elevating regional environmental pollution governance level.
