Analysis Of The Footprint Family At The Sectoral Level In Beijing

With the rapid development of economic, population growth and urbanization, Beijing, the political, economic, cultural and transportation center of China, has more and more serious environmental pollution—waste of resources, energy shortage, water shortageand greenhouse gas emissions which has restricted the development of the sectors and social.Therefore, how to evaluate the impact of sectoral development on the resources and environment and provide the environmental protection to the sustainable development of economy has become the most important task in Beijing.This study examines the footprint family generated by Beijing 42 sectors from 2000 to 2010 by using an input-output structural decomposition analysis method. The land utilization, water footprint trend and the influence of the changes of carbon dioxide (CO2) emissions at sectoral level were calculated. Based on this analysis, structural decomposition analysis was conducted to evaluate the driving factors from the perspective of technology, sectoral connection, economic structure and economic scale. The results show that:the total ecological footprint average in Beijing was 4626153.4 hectares, with an average annual growth rate of 25% from 2000 to 2010. Among them, the agricultural sector caused the highest total ecological footprint, which accounted for more than 85% of the total ecological footprint; The water footprint intensity showed a downward trend with an average annual decline rate of 41%, however, the water footprint of the agricultural sector showed an increased trend, the average annual growth rate was 54%; The carbon footprint intensity is decreasing year by year, however,the total carbon footprint is increasing with an average annual growth rate was about 54% except the year 2007. There are 2 main factors made the total water footprint and carbon footprint declined:the perfection and innovation development of technology, and the adjustment of the economic structure.In addition, the economic scale expansion and the unreasonable communication and coordination among sectors led to the significant increase in water footprint and carbon emissions growth in Beijing.In order to solve the environment pressure problems of Beijing’s sectors, these three important aspects are necessary:the rational allocation of ecological land use, water resource management and energy saving-emission reduction.It is momentous to analysis the impacts of production activities on the environmental influence and the key factors of pollution discharge reduction of resources and energy. This study can not only provide a scientific basis for Beijing to explore the green, sustainable development of the sector, but also provide a reference for similar studies in other cities of our country.
