In this paper,the authors have empirically analyzed the convergence in per capita GDP gap and the convergence in the variation of energy intensity with respect to the change of per capita GDP between China and eight developed countries.Then,the authors run a regression on the impact of decisive factors of economic growth on energy intensity and its change,so as to find out the economic mechanism of energy intensity gap changing with respect to the variation of economic growth.This study concludes that:First,there is a convergence in per capita GDP gap between China and the eight developed countries.With the convergence in per capita GDP gap,the energy intensity gap between China and eight different countries also converge,and the convergence rate of the latter is faster than that of the former,i.e.if the per capita GDP gap between China and the eight developed countries decreases by 1%,the energy intensity gap between them will correspondingly decrease by 1.552%.Second,the energy intensity decreases with the improvement of industrial structure,the rising of energy prices,the advances of technology,and the expansion of investment in fixed assets,and it slightly increases with the increase of FDI.Third,the energy intensity gap between China and eight developed countries narrows with the lessening of the difference in fixed assets investment,energy prices,and technological progress between China and eight developed countries,yet increases with the narrowing of the difference in FDI,and has no significant correlation with the difference in industrial structure.Fourth,the narrowing of difference in per capita GDP between China and the eight developed countries can result in the lessening of energy intensity gap,whose economic mechanism is that the decisive factors,such as difference in investment,technology,and the competition mechanism of prices,which can determine the difference in economic growth,can significantly affect the energy intensity gap. 展开更多

应急管理拥有专门机构和专职队伍,行使专业管理职能,分别嵌入党中央“统”、国务院“总”和省级单元“分”的中央上层结构,以及党委领导(统)、政府主导(总)、各级执行落实(分)的地方下层结构,从而形成应急管理“统-总-专-分”双层嵌入... 应急管理拥有专门机构和专职队伍,行使专业管理职能,分别嵌入党中央“统”、国务院“总”和省级单元“分”的中央上层结构,以及党委领导(统)、政府主导(总)、各级执行落实(分)的地方下层结构,从而形成应急管理“统-总-专-分”双层嵌入结构。在结构与运行保持一致的情形之下,应急管理现代化事业分别采取了“统字当头、执行为主、规划优先”的结构规定性策略和“主体赋能、结果赋权、过程协同”的运行增能性策略。在结构优化视阈下,需处理好“统与分、防与救、破与立、上与下、内与外”五对基本关系,不断优化应急管理体系,持续推进应急管理现代化。 展开更多
