生产性服务业集聚促进能源利用结构优化了吗?——基于动态空间杜宾模型的实证分析

Does the Agglomeration of Productive Services Promote the Optimization of Energy Utilization Structure? An Empirical Analysis Based on Dynamic Spatial Durbin Model

基于31个省区市的面板数据,采用动态空间杜宾模型探讨生产性服务业集聚对能源利用结构的影响,结果显示:生产性服务业专业化集聚有助于促进本地区能源利用结构优化,但对周边地区能源利用结构优化却产生了负向空间外溢效应;生产性服务业多样化集聚对本地区和相邻地区的能源利用结构优化均具有明显的促进作用,且长期影响大于短期影响。进一步研究发现,科学研究和技术服务业及环境治理和公共设施管理业的专业化和多样化集聚均显著促进了本地区和周边地区的能源利用结构优化;交通运输仓储和邮政业、批发零售业、租赁和商务服务业专业化和多样化集聚仅对本地区能源利用结构优化具有促进作用,对周边地区未产生积极影响;信息传输、计算机服务和软件业集聚对能源利用结构优化的促进作用仅有长期效应而无短期影响;金融业专业化和多样化集聚在短期和长期均显著抑制了本地区和周边地区能源利用结构优化。

Based on the panel data of 31 provinces and municipalitres,this paper uses the dynamic Spatial Durbin Model to study the effect of the agglomeration of productive services on energy utilization structure. The results show that,the specialized agglomeration of productive services helps to promote the optimization of energy utilization structure in the local regions themselves,but the optimization of the energy utilization structure in the surrounding areas has produced negative spatial spillover effect,and the long-term impact is greater than the short-term one. Further studies show that,the specialized agglomeration and diversified agglomeration of scientific research and technical services,environmental governance and public facilities management have significantly promoted the optimization of energy utilization structure in the local and neighboring regions.However,the specialized agglomeration and diversified agglomeration of transportation,warehousing and postal services,wholesale and retail,leasing and business services only promote the optimization of energy utilization structure in local regions,and have no positive impact on the surrounding areas. And the promotion effect of specialization of information transmission,computer services and software on the optimization of energy utilization structure only has long-term effect,without short-term effect. The specialized agglomeration and diversified agglomeration of the financial industry significantly inhibits the optimization of energy utilization structure in local and surrounding provinces,whether in the short or long term.
