The minimum number of total independent partition sets of V ∪ E of graph G（V,E） is called the total chromatic number of G denoted by χt（G）. If the difference of the numbers of any two total independent partition sets of V ∪ E is no more than one＇, then the minimum number of total independent partition sets of V ∪ E is called the equitable total chromatic number of G, denoted by χet（G）. In this paper, we obtain the equitable total chromatic number of the join graph of fan and wheel with the same order.

基于2004—2020年中国省级面板数据,通过构建耦合协调度模型测算社会福利水平与资源消耗之间的协调程度。然后,构建空间杜宾模型实证检验两者耦合协调发展的驱动机制并对各驱动因素的空间效应进行分解。研究结果显示:(1)研究期间内,中国社会福利水平与资源消耗之间的耦合协调度整体呈上升趋势,仅个别年份存在回落现象;西部地区耦合协调度低于东、中部地区,而中部地区后来居上,于2017年反超东部地区;上海、北京耦合协调度一直处于领先水平,天津2015年后耦合协调度递减明显。(2)经济规模、产业结构、技术进步、能源消费结构、能源强度、外商投资以及政府规模显著驱动社会福利水平与资源消耗耦合协调发展。(3)社会福利水平与资源消耗耦合协调发展的过程中对周边地区存在正向空间溢出效应,各驱动因素对耦合协调度的影响也存在空间溢出效应。其中,产业结构、技术进步与能源消费结构的直接效应与间接效应方向相反。
