Abstract: There is some important guidance significance for researching the indicators and their weightings of ecological civilization to objectively evaluate ecological civilization. To overcome some defects of indicators and their weightings in measurement of ecological civilization, the paper constructs the method combining pressurestateimpactresponse with structural equation modeling to optimize for screening the final indicators and to measure its indicators’ weightings with the dynamic panel data of China and 31 provinces from 2007 to 2016. And then the indicators’ weightings by PSIRSEM, AHP and entropy method are compared to conclude some characteristics and advantage of the method of PSIRSEM in this paper. Research indicates these followings. (1) The indicator system of ecological civilization contains society industry economy (eight indicators), resources and environment (nine indicators), ecology benefit (seven indicators), ecological civilization response (ten indicators) and they have mutual relationship of each other. Here ecology indicators and ecological civilization response are strengthened while industry economy indicators are weakened, which is more reasonable than the current existing researches of leaving ecological civilization response out of consideration and strengthening economy indicators instead of ecology indicators. (2) The indicators’ weightings of ecological civilization are respectively ecological civilization response (0.292 9), ecology benefit (0.250 3), society industry economy (0.239 3), resources and environment (0.225 3). The weightings between ecology indicators and economy indicators are balanced and are not great difference, which can entirety reflect the essential attribute of ecological civilization. (3) In all thirtyone provinces, the quantities of provinces which are at state of ecological civilization (including fourteen provinces, fortyfive point one six percent) are more than the quantities of provinces which are not at state of ecological civilization (including seventeen provinces, fiftyfour point eight four percent), which is more reasonable than the current existing research that whether the regions are at state of ecological civilization or not, ecological civilization will be evaluated directly 〗
