【摘要】：基于广义的低碳经济视角,将能源消耗强度低于制造业的平均水平作为筛选高技术制造业的标准之一,在界定高技术制造业基础上,采用基于投入产出表的结构分解技术对天津市各产业部门在消耗能源过程中排放的二氧化硫、氮氧化物和PM2.5一次源等主要污染物进行了结构分解分析,研究了各种污染物排放强度、技术水平和最终需求变动各自的影响,并据此测算了高技术制造业对这些污染物减排的贡献度。研究发现,通用、专用设备制造业,电气机械和器材制造业,通信设备、计算机和其他电子设备制造业对这几种主要污染物的减排做出了重要贡献,仪器仪表制造业对减排的贡献相对较小,而交通运输设备制造业对这几种主要污染物的排放量都在显著增加,化学产品加工业对氮氧化物的排放量也有所增加。通过原因分析,提出了一些具有针对性的政策建议。
[Abstract]:The perspective of low carbon economy based on the generalized standard of energy consumption intensity is lower than average level of the manufacturing industry as the screening of high technology manufacturing industry, the definition of high technology manufacturing industry based on the technology of each industry department in Tianjin city of sulfur dioxide emissions from energy consumption in the process of structure decomposition based on the input-output table, the main pollutants nitrogen oxides and PM2.5 a source of structural decomposition analysis, the intensity of the emission of various pollutants, the technical level and the final demand change their influence, the paper calculates the contribution of high technology manufacturing industry of these pollutants emission. The study found that in general, special equipment manufacturing, electrical machinery and equipment manufacturing industry. Communication equipment, make an important contribution to emission reduction of computers and other electronic equipment manufacturing industry of the main pollutants, instrument manufacturing industry of emission reduction contribution To a lesser extent, transportation and equipment manufacturing industry has significantly increased the emissions of these major pollutants, and the emissions of chemical products processing industry also increased. By analyzing the causes, some specific policy recommendations were put forward.
