Research on the Coupling Coordination between Digital Technology Innovation and Industrial Green and Low-carbon Development
By constructing the evaluation index system of digital technology innovation and industrial green and low-carbon development,based on the panel data of 30 provinces(autonomous regions,province-level municipalities)from 2011 to 2020,this paper calculated the comprehensive evaluation index of digital technology innovation and industrial green and low-carbon development at the provincial level by using the entropy method,and established the coupling coordination model of digital technology innovation and industrial green and low-carbon development.The Dagum Gini coefficient method was used to analyze the regional differentiation of coupling coordination degree.The results show that during the sample period,the average index values of digital technology innovation and industrial green and low-carbon development at the national and regional levels show an upward trend,but the values of both indexes are low and the development level of each region has a certain gap.At the national level,the coupling coordination degree of digital technology innovation and industrial green and low-carbon development shows a stable upward trend,and the coupling coordination level developed from the verge of imbalance to barely coordination,but there is a big gap between different regions.The coupling coordination level of the eastern region has been developed to the primary coordination stage,while both the northeastern region and the central and western region have been developed to a barely coordinated stage.Both the overall Gini coefficient and the intra-regional Gini coefficient of the coupling coordination degree between digital technology innovation and industrial green and low-carbon development show a downward trend to varying degrees.The regional differences of the coupling coordination degree mainly come from the inter-regional differences.Finally,policy suggestions are put forward to improve the level of digital technology innovation and industrial green and low carbon development and promote their coordinated development.
