Abstract:

This study analyzes the development level,spatiotemporal evolution and main constraining factors of China's new quality productive forces in forestry to provide a basis for optimizing the cultivation path for new quality productive forces in forestry.Based on the panel data from 31 provincial-level administrative regions in China from 2013 to 2022,this study constructs an evaluation index system from three dimensions:new-quality laborers,new-quality means of labor,and new-quality objects of labor.An improved variable-weight matter-element extension model is adopted to measure the development level of new quality productive forces in forestry,and the Dagum Gini coefficient and the obstacle degree model are used to analyze regional differences and the main obstacle factors.1)From 2013 to 2022,China's new quality productive forces in forestry were generally at a medium level and had not yet reached a good level.Spatially,it presents a pattern in which the eastern region led,the central region followed,and the western region lagged behind.2)The national Dagum Gini coefficient ranged from 0.005 to 0.008,indicating that the overall regional differences were relatively small,although the uneven development within regions still persisted.3)The main obstacle factors have gradually shifted from insufficient fixed asset investment,inadequate forest health management,and insufficient cultivation of new-quality industries to low labor efficiency,insufficient supply of science and technological service,inadequate infrastructure support,and insufficient and upgrading of traditional industries toward new-quality development.China's new quality productive forces in forestry are still at the stage of cultivation and improvement.Efforts should therefore be made to improve the training system for new-quality laborers in forestry and strengthen forestry science and technology services;accelerate the upgrading of new-quality means of labor in forestry and enhance investment and equipment support;and improve the utilization mechanism for new-quality objects of labor in forestry and expand channels for realizing the value of forestry resources.

Key words: new quality productive forces in forestry, variable-weight matter-element extension model, spatiotemporal evolution, obstacle factors
