DOES WATER ECOLOGICAL CIVILIZATION URBAN CONSTRUCTION PILOT IMPACT GREEN EFFICIENCY OF INDUSTRIAL WATER RESOURCES?
Water ecological civilization urban construction pilot(WECCP)is a key way to ecological civilization construction,meaningful to China's quality economic development.This paper,taking WECCP as a quasi-natural experiment,selects 2006 to 2021 panel data of China's 248 cities to establish a progressive DID model,which is used to study how the pilot impacts industrial water resources green efficiency.Heterogeneity analysis of region,economy and industrial basis is carried out by grouped samples via mediating effect's three-stepped mechanism.WECCP can dramatically increase industrial water resources green efficiency by passing robustness tests such as parallel trend test,placebo test,replacement measurement model and PSM.Mediating effect of impacting mechanism of industrial structural upgrading is 12.17％of the total effects,and green technical innovation is 45.43％,suggesting industrial structural upgrading and green technical innovation can largely impact WECCP as two vital mechanisms.Heterogeneity exists in the impacts of WECCP,which plays a more outstanding role in improving industrial water resources green efficiency in eastern China with higher economic level and non-old industrial bases than in central-western China with low economic level and old industrial bases.This paper presents suggestions on continuing WECCP,planning industrial structure and raising green innovative capabilities and appropriately constructing water ecological civilization plans.
