Asymmetric Influence of Economic Growth on the CO₂ Emissions from Construction Industry in China

In order to analyse the asymmetric impact of economic development on the carbon emissions from construction industry in China, this paper constructed an extended model of influencing factors for CO₂ emissions from construction industry including economic growth, collected the relevant data of China's 30 provinces during 1997-2015, and tested threshold effect of China's economic growth on CO₂ emissions from construction industry by the panel threshold regression model empirically. The results show that: (1) Economic growth, population size, industrial scale and energy structure have positive impacts on CO₂ emissions from construction industry, while energy efficiency has negative impacts. (2) Economic growth has a significant double threshold effect on CO₂ emissions of construction industry, and it has a positive effect under the three regimes. Its intensity of effect increases first and then decreases with the economic level across the two thresholds. As a result, the Chinese government should pay more attention to the asymmetric influence of economic growth at different stages of development when formulating the construction industry emission reduction policies.
