基于全局时序因子分析的中国区域绿色技术创新环境评价OACHSSCDCSTPCD

To investigate the level of green technology innovation environment and its promotion path,a regional-level evaluation index system for the green technology innovation environment was constructed based on data samples from 31 provinces in China from 2017 to 2021.The principal dimensions effectively influencing the green technology innovation environment were identified using a global time series factor analysis method,and the environmental level of green technology innovation was scored.A"butterfly model"was used to compare regional differences.The study revealed that four primary dimensions affecting the green technology innovation environment were basic public services,urban development,policy efficiency,and resource supply and green living.There were significant differences in the green technology innovation environment levels among regions,with the greatest differences observed in resource supply and green living and urban development.Finally,based on the regional location,resource endowment,and economic development characteristics of each region,the advantages and disadvantages of their development were thoroughly explored,and targeted policy recommendations were proposed.It is suggested that policy guidance,increased investment,and expanded openness should be employed to facilitate cross-regional resource flow and enhance the environment for green technological innovation.
