Abstract：
Green production, which reduces hazardous industrial discharges per unit output, is promoted throughout China. The Environmental Kuznets Curve suggests a negative correlation between hazardous industrial discharge and economic growth due to green innovation. This study expanded the EKC framework by including heterogeneity in evaluating the relationship between hazardous industrial discharges and economic growth to reflect green transformation. Administrative ranking disparity is identified as one of the fundamental driving forces of green production transition in a developing country. Building on an enriched EKC framework, we used a spatial estimation model to exclude spatial effects and obtained accurate estimates of the classified regions. The modified research method was used to examine whether industrial pollution has been reduced in 267 cities and towns in China from 2007 to 2021. Environmental protection performance was examined to estimate whether there is a switch to green manufacturing. As industrial hazards are of different types, the author sought to determine whether there was a decrease in industrial sulphur dioxide emissions, wastewater, solid waste, or dust, even though more industrial hazards were recycled than before. The spatial estimates indicated that (a) the national level of pollution remains positively linked with the total output, and every percentage of output growth increases sulphur dioxide emissions by 444.573 tons; (b) a positive relationship between economic growth and wastewater is altered by environmental protection in cities, while the general decoupling between economic growth and other types of industrial pollution, such as solid waste and industrial dust, was not observed; (c) growth in the southeast was decoupled from sulphur emissions, and its sulphur dioxide production per unit of output increased to 0.021 tons. Sulphur dioxide emissions per unit of economic growth along the southeast coast were 379. 048 tons, which was well below the overall average of 444.573 tons. High-income towns along the southeast coast have achieved clean production breakthroughs, realising a 15% reduction in industrial sulphur dioxide emissions by 2021. Although there were signs of a shift toward clean manufacturing in high administrative ranking cities, most regions of China are transitioning to environmentally friendly manufacturing and suffer from the hardships of green production transformation.
摘要：
绿色生产,这减少了单位产出的有害工业排放，在中国各地推广。环境库兹涅茨曲线表明，由于绿色创新，有害工业排放与经济增长之间存在负相关关系。本研究通过在评估有害工业排放与经济增长之间的关系中纳入异质性来扩展EKC框架，以反映绿色转型。行政级别差异被认为是发展中国家绿色生产转型的基本动力之一。建立在丰富的EKC框架上，我们使用空间估计模型来排除空间效应，并获得分类区域的准确估计。采用改进的研究方法，考察了2007年至2021年中国267个城镇的工业污染是否有所减少。检查了环境保护性能，以估计是否有向绿色制造的转变。由于工业危害的类型不同，作者试图确定工业二氧化硫排放量是否有所减少，废水,固体废物,或灰尘，尽管回收的工业危害比以前多。空间估计表明，(a)全国污染水平仍然与总产出呈正相关，产出每增长一个百分比，二氧化硫排放量就会增加444.573吨；(b)城市环境保护改变了经济增长与废水之间的正相关关系，虽然经济增长和其他类型的工业污染之间普遍脱钩，如固体废物和工业粉尘，没有观察到；(C)东南部的增长与硫排放脱钩，单位产量二氧化硫产量增加到0.021吨。东南沿海经济增长单位二氧化硫排放量为379。048吨,远低于444.573吨的整体平均水平。东南沿海高收入城镇实现清洁生产突破,到2021年实现工业二氧化硫排放量减少15%。尽管在高行政级别的城市有向清洁制造业转变的迹象，中国大部分地区正在向环保制造转型，并遭受绿色生产转型的艰辛。
