基于产业关联的碳减排绿色科技发展路径研究——以广东省为例

Research on the green technology path of carbon emission reduction based on industrial correlatio: a Case Study of Guangdong ProvinceHong Namei1,2

摘要:

以广东省2017年投入产出表及能源消耗数据为基础数据,运用假设抽取法测算能源消耗的产业关联性。结果表明：(1)炼焦化工金属产品制造业直接能耗总量最大,交通运输、仓储和邮政业单位能耗最大,是直接碳减排重点关注部门。(2)炼焦化工金属产品制造业、交通运输、仓储和邮政业、采掘业及电力燃气及水的生产供应业转移输出碳排放量比重最大,是间接减排重点关注部门。(3)机械设备制造业、建筑业是吸收碳转移最多的两个部门,机械设备制造业本身及炼焦化工金属产品制造业是主要输入部门,也是间接减排重点关注部门。最后从重点产业部门绿色科技发展路径、绿色能源科技创新路径、产业结构优化助力绿色科技发展及政策导向支持绿色科技发展四个方面推进经济系统的绿色科技发展。

Abstract:

Based on the input-output table and energy consumption data of Guangdong Province in 2017, using the improved hypothetical extraction method to measure the industrial relevance of energy consumption. The results show that:(1) the total direct energy consumption of coking, chemical and metal products manufacturing industry is the largest, and the unit energy consumption of transportation, warehousing and postal services industry is the largest. They are the key departments of direct carbon emission reduction. (2) Coking, chemical and metal products manufacturing, transportation, warehousing and postal services, mining and power, gas and water production and supply industries account for the largest proportion of transferred carbon emissions, and are the key departments for indirect emission reduction. (3) The mechanical equipment manufacturing industry and the construction industry are the two sectors that absorb the most carbon transfer. The mechanical equipment manufacturing industry itself and the coking, chemical and metal products manufacturing industry are the main input sectors, and they are also the key sectors for indirect emission reduction. The key industrial sectors’ green technology development, the green energy’s development, the optimization of industrial structure and policy guidance will be the key to the green technology development of the economic system.
