Analysis regional differences and dynamic evolution of comprehensive utilization level of crop straw in China
Combined with the panel data of 31 provinces(municipalities and districts)in China from 2013 to 2022(excluding Hong Kong,Macao and Taiwan),the entropy method,Dagum Gini coefficient,kernel density estimation method and Moran's I were used to study the regional diffe-rences and spatiotemporal dynamic evolution of straw comprehensive utilization level in China.The results showed that from 2013 to 2022,the level of comprehensive utilization of crop straw in Chi-na was significantly improved,and there were differences in regional development levels,and there were obvious differences between the eastern,central and western regions.The overall polarization phenomenon of the whole country was weakened,and there was a multi-regional differentiation phenomenon in the central region,but there was no obvious polarization phenomenon in the eastern and western regions.There was a significant spatial positive correlation between the comprehensive utilization level of crop straw in China,and there was a high degree of aggregation in geographical location,and the spatial agglomeration characteristics were stable.
