【摘要】：文章基于京津冀地區(qū)城市空氣質(zhì)量指數(shù)(AQI)日報數(shù)據(jù),在VAR模型框架下,采用非線性格蘭杰因果檢驗方法對城市大氣污染的非線性傳導關(guān)系進行識別,并借助社會網(wǎng)絡分析方法揭示其聯(lián)動網(wǎng)絡結(jié)構(gòu)特征。研究表明,京津冀地區(qū)城市間大氣污染存在較為顯著的非線性傳導關(guān)系,且構(gòu)成了復雜的聯(lián)動網(wǎng)絡。在穩(wěn)健性網(wǎng)絡中,石家莊、衡水、滄州、北京、秦皇島、承德、邯鄲處于網(wǎng)絡核心,其他6個城市處于網(wǎng)絡邊緣。在最大可能性網(wǎng)絡中,京津冀地區(qū)的13個城市沒有呈現(xiàn)出明顯的核心—邊緣結(jié)構(gòu),大氣污染聯(lián)防聯(lián)控要求13個城市必須步調(diào)一致�；谏鲜鼋Y(jié)論,文章提出了基于"污染程度—網(wǎng)絡位置"的二維分析框架,為完善京津冀地區(qū)大氣污染的聯(lián)防聯(lián)控機制提供了決策支持。
[Abstract]:Based on the (AQI) daily data of urban air quality index in Beijing-Tianjin-Hebei region, the nonlinear Granger causality test method is used to identify the nonlinear conduction relationship of urban air pollution under the framework of VAR model. And with the help of social network analysis method to reveal its linkage network structure characteristics. The results show that there is a significant nonlinear conduction relationship between cities in Beijing-Tianjin-Hebei region and a complex linkage network is formed. In the robust network, Shijiazhuang, Hengshui, Cangzhou, Beijing, Qinhuangdao, Chengde, Handan are at the core of the network, the other six cities are on the edge of the network. In the most probable network, 13 cities in Beijing-Tianjin-Hebei region do not show a distinct core-edge structure, and the air pollution control requires 13 cities to be in step with each other. Based on the above conclusions, a two-dimensional analysis framework based on "degree of pollution-network location" is proposed, which provides decision support for improving the joint control mechanism of air pollution in Beijing-Tianjin-Hebei region.
