Measurement of rapeseed production capacity utilization and regional differences in China
摘要
Abstract
With the continuous progress of agricultural modernization,rapeseed industry is facing a challenge of transitioning from traditional production models to greener,more efficient,and more sustainable production sys-tem.Based on input-output panel data from 15 provinces in China from 2004 to 2023,we employs a radial efficien-cy model using directional distance function to calculate both traditional and sustainable capacity utilization rates of rapeseed industry at 3 levels on national,regional,and provincial.We also analyzed its evolution trends and region-al differences.Results indicate that China's rapeseed industry has a traditional capacity utilization rate of 75.97％and a sustainable capacity utilization rate of 95.05％,which exhibiting slight overcapacity under traditional produc-tion model,and a certain degree of underutilization under sustainable model.At regional level,the traditional capac-ity utilization rate in southwest winter rapeseed production area is within the reasonable range,while the Yangtze River Middle and Lower Reaches winter rapeseed area and northern spring rapeseed production area are in a slight overcapacity range.However,all regions face issues of insufficient sustainable capacity utilization,with the North-ern spring rapeseed area showing a more significant shortfall.At the provincial level,Sichuan,Shaanxi,Gansu,and Yunnan have made relatively full use of their traditional capacity,while most other provinces face the dual challeng-es of overutilization of traditional capacity and insufficient use of sustainable capacity.Overall,the disparities in both traditional and sustainable capacity utilization rates of rapeseed in China have been narrowing,showing a trend toward optimization and balance.关键词
