我国环境服务业发展水平评价

Evaluation on the development level of environmental service industry in China

环境服务业作为生产性服务业和环保产业的重要组成,是我国经济发展的重要引擎。基于环境服务业定义和类别的演变,在分析我国环境服务业发展现状的基础上,构建包含产业结构、产业规模、产业盈利能力、产业集中度、产业创新能力5个维度的指标体系,采用主成分分析法对我国2015-2017年环境服务业发展水平进行综合评价。结果表明:我国环境服务业的综合发展水平呈逐年上升趋势,与各类指标分析结果相一致。从2015-2017年环境服务业综合指数来看,环境服务业经济增长能力因子在2017年最大,表明其当年综合发展水平的提升主要是由于经济增长能力因子的提高;环境服务业规模技术增长能力因子在2016年最大,表明当年的技术增长能力的提升促进了环境服务业综合发展水平的提升。针对评价结果,从扩大环境服务业企业规模,培育龙头企业,提升环境服务业企业技术创新增长能力,完善环境服务业保障措施等方面提出促进我国环境服务业发展水平的对策。
