摘要/Abstract

摘要： 环保支出是精细化工企业解决环境污染的基本保障,是提升企业绿色可持续发展能力的重要途径。生态效率作为评估绿色发展水平的重要指标,研究精细化工企业环保支出对生态效率的影响规律和机理,有助于协同推进企业经济增长和污染减排,为企业高质量发展提供支撑。本研究采用SBM-GML模型测算了2011—2021年上虞园区55家精细化工企业的生态效率,从时间、产权及子行业多维度分析了环保支出对生态效率的异质性影响,在此基础上构建门槛模型探讨环保支出对生态效率的作用机理。结果表明:2011—2021年,园区精细化工企业生态效率水平提高了55.5%,环保支出对生态效率起到了正向作用,且在“十二五”期间内资及医药企业中效果更为显著。企业资源利用效率提升,进一步促进环保支出对生态效率的正向作用；绿色技术水平超过门槛值,环保支出对生态效率的影响不显著；环保支出占总成本比重超过48.8%,环保支出对生态效率影响程度大幅减弱。基于上述结论,提出精细化工企业提升生态效率水平的具体建议,为企业制定环保实施方案提供支撑。

Abstract: Environmental expenses of fine chemical entities is a general guarantee to environmental pollution, and also a vital approach to entities' green sustainability. Eco-efficiency is an important index for evaluating green development. Study of impacts and mechanism of environmental expenses on eco-efficiency of fine chemical entities is helpful to drive economic growth and reduce pollution, offering supports to entities' quality development. This paper uses SBM-GML model to estimate 2011 to 2021 eco-efficiencies of 55 fine chemical entities in Shangyu industrial park, and analyzes the heterogeneity of environmental expenses on eco-efficiency from timescale, property and sub-industries. A threshold model is established to discuss the mechanism of environmental expenses on eco-efficiency. Fine chemical entities in the park have increased their eco-efficiency by 55.5% from 2011 to 2021, positively driven by environmental expenses, more outstandingly among internal capital and medicine entities during the “12-^th 5-Year-Plan”. Entities have raised their resources utilization efficiency, further promoting the positive pushing of environmental expenses on eco-efficiency. Environmental expenses exert little impacts on eco-efficiency when green technology is above the threshold value, and will largely decrease impacts when environmental expense is 48.8% more than the total cost. This paper presents suggestions for fine chemical entities to improve eco-efficiency and provides supports to make environmental plannings.

Key words: fine chemicals, environmental expense, eco-efficiency, threshold effect
