生态-经济型投入产出表的构建与应用——以北京市为例

Construction and Application of Ecological-Economic Input-Output Table:A Case Study of Beijing City

随着中国加强生态环境建设投资,生态相关产业的兴起被视为潜在的经济增长点。然而,现行国民经济核算体系未将生态产业列为独立产业,也未计入其对环境改善所贡献的生态服务价值。选取北京作为研究区,采用投入产出分析法,首次将生态产业单列,并将生态系统服务价值纳入计算,以此分析其对国民经济的贡献。研究结果显示,生态产业对经济社会具有积极的拉动效果,其影响力系数达到1.017。生态产业投资对水利环境等公共服务行业,以及房地产、餐饮、娱乐等直接受益行业有较好的促进作用,而对制造业及其他服务业的增长贡献较少。从国民经济的整体来看,生态投资促进了教育和金融领域的发展,每单位生态投资可使区域GDP增长1.318倍。

As China bolsters,its investment in ecological and environmental construction,the rise of ecology-related industries is considered a potential area for economic growth.However,the current national economic accounting system does not classify the ecological industry as an independent sector or account for the ecological service value contributed to environmental improvement.Taking Beijing as the research area,the input-output analysis method was used to distinguish the ecological industry for the first time.It includes the value of ecosystem services in the calculation to assess its contribution to the national economy.The findings indicate that the ecological industry positively affects the socioeconomic dynamic,with an influence coefficient of 1.017.Investments in the ecological industry effectively promote public service sectors such as water conservation and the environment,as well as directly benefiting industries like real estate,hospitality,and entertainment while contributing less to manufacturing and other service industries.Looking at the overall national economy,ecological investments have significantly advanced the education and finance sectors,with each unit of ecological investment potentially increasing the regional GDP by 1.318 times.
