A Study on the Influencing Factors of Carbon Emissions in Provincial Construction Industry Based on LMDI Model–Taking Shandong Province as an Example

Abstract

This paper takes the construction industry in Shandong Province as the research object and calculates the CO2 emissions of the construction industry in Shandong Province for 15 years from 2005 to 2019 by using the IPCC carbon emission factor method, and analyzes the factors influencing the carbon emissions of the construction industry in Shandong Province from five aspects, such as carbon emission intensity, energy consumption structure, energy intensity, economic level, and population scale, by Logarithmic mean Divisia index (LMDI) decomposition method. The analysis result indicates that energy intensity and economic level are the critical factors influencing the change in carbon emission in Shandong Province’s construction industry. Among them, the economic level is the major factor that promotes the positive growth of carbon emissions in Shandong Province’s construction industry, with a contribution rate of 2329.39% of the total effect; energy intensity is an important factor that suppresses carbon emissions in Shandong Province’s construction industry, with a contribution rate of −2739.81%.
