【摘要】：运用空间联立方程模型考察了人口集聚、工业集聚、经济集聚与雾霾污染的相互作用机制。结果显示:雾霾污染存在显著的空间溢出效应;工业集聚和雾霾污染呈正相关关系,人口集聚、经济集聚和雾霾污染之间呈负相关关系;我国经济集聚和雾霾污染之间已进入倒"U"型曲线的下降阶段;雾霾污染会对当地的经济产生挤出效应,从而使周边地区从中受益。为了考察城镇化率的差异对集聚和雾霾污染作用机制的影响,采用门槛模型对此进行了研究,结果显示:随着城镇化率的提高,工业集聚和雾霾污染之间呈倒"U"型关系,当城镇化率大于68.60%时,工业集聚和雾霾污染之间呈负相关关系;随着城镇化率的提高,经济集聚和雾霾污染之间的负相关关系越来越显著。
[Abstract]:The interaction mechanism of population agglomeration, industrial agglomeration, economic agglomeration and haze pollution was investigated by using spatial simultaneous equation model. The results showed that there were significant spatial spillover effects on haze pollution, positive correlation between industrial agglomeration and haze pollution, and negative correlation between population agglomeration, economic agglomeration and haze pollution. China's economic agglomeration and haze pollution have entered the downward stage of the inverted "U" curve, and the haze pollution will have an crowding out effect on the local economy, thus benefiting the surrounding areas. In order to investigate the effect of the difference of urbanization rate on agglomeration and haze pollution mechanism, the threshold model was used to study it. The results showed that with the increase of urbanization rate, the relationship between industrial agglomeration and haze pollution was inverted "U" type. When the urbanization rate is greater than 68.60, there is a negative correlation between industrial agglomeration and haze pollution, and with the increase of urbanization rate, the negative correlation between economic agglomeration and haze pollution becomes more and more significant.
