This paper, based on 2015—2019 panel data of China's 163 listed new energy companies, uses fixed effect model to study the impacts of governmental subsidies on operating performance of new energy companies, and discusses the adjustment of governmental subsidies on commercial operating performance under enterprises life circle, and uses grouped regression to check the effect of governmental subsidies on commercial operating performance amid different ownerships and marketization. Results show an upside-down U-shaped relation between governmental subsidies and commercial operating performance in new energy industry, outstandingly for growing companies, private companies, and in highly-marketized regions. Property ownership exerts a large adjustment.

This paper, based on panel data of 16 cities of 2007, 2012 and 2017 in Shandong province, establishes a coordination model of population-economy-environment based on entropy and physical coupling model, which is used to study the temporal-spatial evolution of population-economy-environment system coupling coordination and to estimate their spatial Moran's indexes, and presents suggestions for Shandong's future development. Among 16 cities in Shandong province, their coupling coordination is improving thanks to a rising comprehensive development. The western inland is far behind the eastern and central in economy and population. A low spatial autocorrelation exists in their economy-population-environment development, but weakly positive between comprehensive development and coordination. Regional coordinated potential needs to be further developed.
