Embodiment 1

[0049] a kind of SO 2 The method for quantifying the drivers of emission change consists of the following steps:

[0050] Step (1), get SO 2 Direct emissions data

[0051] According to the "China Environmental Statistical Yearbook", the SO2 emission data of 42 economic sectors in the country in 2002, 2005, 2007, and 2012 were respectively obtained. The 42 economic sectors are: agriculture, coal mining and washing industry, oil and natural gas extraction industry, Mining and dressing of metal ores, mining and dressing of non-metallic ores and other minerals, food manufacturing and tobacco processing, textile industry, clothing, leather, down and its products, wood processing and furniture manufacturing, paper printing and cultural, educational and sporting goods manufacturing, Petroleum processing, coking and nuclear fuel processing, chemical industry, non-metallic mineral products industry, metal smelting and rolling processing industry, metal products industry, general and ...

Abstract

The invention discloses a regional production-caused SO2 emission change driving force quantification method. From the perspective of producers, through analyzing change of driving factors such as local technological advancement, local industrial restructuring, local consumption and external consumption, the structural decomposition method based on input-output analysis is adopted, the economic driving force for SO2 emissions in various industrial sectors in the region is made to be clear, change of SO2 emission caused by local production is analyzed. The method is advantaged in that through quantifying an industrial restructuring coefficient, a technological progress coefficient and final demand change, scientific basis and support are provided for targeted reduction of SO2 emission, andthe method has the important scientific value.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a SO 2 Emissions Change Driver Quantification Approach. Background technique [0002] At present, my country's air pollution is serious, and problems such as coal-supported energy structure and imperfect desulfurization technology have led to sulfur dioxide (SO 2 ) a large number of emissions, which has attracted widespread attention. Therefore, a method that can be used to analyze and drive SO 2 The research program of emission change has important practical significance. [0003] Existing studies have mostly adopted the perspective of consumers to examine the SO driven by regional consumption changes. 2 Changes in emissions, which include both local SO due to local production 2 Emissions also include off-site SO emissions from off-site imports of products 2 emission. The consumer perspective can reveal the impact of regional consumption activities on SO i...
