IMPACTS AND MECHANISM OF ENVIRONMENTAL EXPENSES ON ECO-EFFICIENCIES OF FINE CHEMICALS ENTITIES
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"12th 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.
