Temperature and industrial output: Firm-level evidence from China

We pair a firm-level panel of annual industrial output with a fine-scale daily weather data set, to estimate the responses of industrial output to temperature changes in China. We have four primary findings. First, industrial output is nonlinear in temperature changes. With seasonal average temperatures as temperature variables, output responds positively to higher spring temperatures and negatively to elevated summer temperatures. With temperature bins as temperature variables, output increases linearly with temperature up to 21–24 °C, and then declines sharply at higher temperatures. Second, lagged temperature changes exert large and significant impacts on current year’s output. Third, higher summer temperatures have larger detrimental effects on output in low-temperature regions than in high-temperature regions, which suggests that adaptation to warming may have been actively undertaken in high-temperature regions in China. Lastly, industrial output in China is projected to decrease by 3–36% by 2080 under the slowest warming scenario (B1) and by 12–46% under the most rapid warming scenario (A2) under the global climate models UKMO-HadCM3 and PCM.

Prospering Revolution of Resource Efficiency in Northeast Industrial Area in China

Despite its strong advantages in resource, technology and human resource, China＇s Northeast Industrial Area is also experiencing problems of unreasonable industrial structure, environmental pollution, and the degradation of ecological condition, etc., which prevent this area from achieving a sustainable devel- opment. Through analyzing the resource problem, the present paper proposed a strategy of circular economy for the prosperity of this are, discussed the theories of circular economy and resource recycling, and finally concluded that improving resource productivity is at the core of circular economy.
