IMPACTS OF NEW ENERGY VEHICLE INDUSTRIAL AGGLOMERATION ON REGIONAL GREEN ECONOMIC EFFICIENCY BASED ON A CASE STUDY ON YANGTZE RIVER ECONOMIC ZONE
This paper incorporates industrial agglomeration,green technical innovation and green economic efficiency to study the impact of new energy vehicle industrial agglomeration on green economic efficiency in Yangtze River economic zone,aiming at offering references for China to reach strategic objectives of manufacturing power and to develop new energy vehicles in Yangtze River economic zone under the dual-carbon settings.This paper,based on 11 provinces/cities'2012 to 2020 panel data along Yangtze River economic zone,uses super-efficiency SBM and locality entropy to establish a measuring model,which is employed to study impacts of new energy vehicle industrial agglomeration on green economic efficiency.And discusses mediating effects of green technical innovation.The spatial overflowing effects and regional heterogeneity of new-energy vehicle industrial agglomeration on green economic efficiency also were analyzed.The entire Yangtze River economic zone has become a zoned new energy vehicle industrial agglomeration area,with its agglomerating level fluctuating up over years,and increasing from down-to upper-stream with growing variance.New energy vehicle industrial agglomeration promotes the green economic efficiency in Yangtze River economic zone through consolidating internal network resources and boosting external entire capabilities.Development of industrial agglomeration promotes green technical innovation through competition and cooperation,and development of green technical innovation can also boost economic drives and efficiency,proving its mediation between industrial agglomeration and green economic efficiency.New energy vehicle industrial agglomeration has spatial overflowing on green economic efficiency,varying among upper-,middle-and down-stream.This paper presents suggestions on enhancing industrial clustering construction to play a role in the long-term mechanism of new energy vehicle industry,boosting green technical innovation system and advancing regional heterogeneity of new energy vehicle.
