摘　　要：运用C-D生产函数模型和索罗余值方程,分析2009—2018年我国15个烤烟产地烤烟生产技术进步贡献率和要素投入贡献率。结果表明,研究期内我国烤烟平均技术进步贡献率144.01%,人工投入、物质和服务投入、土地投入的平均贡献率分别为-69.02%、31.71%、-6.7%,技术进步已成为烤烟产出增长的主要因素,我国烤烟生产已经转向技术进步型增长。结合烤烟生产技术进步情况提出针对性政策建议,以期进一步挖掘我国烤烟生产潜力,实现科技进步贡献率的进一步提升。Using Cobb-Douglass production function model and Solow residual equation,we analyzed the contribution rate of technological progress and factor input of flue-cured tobacco production in 15 flue-cured tobacco producing areas in China from 2009 to 2018.The results showed that the average contribution rate of technological progress of flue-cured tobacco in China was 144.01%,and the average contribution rates of labor input,material and service input and land input were-69.02%,31.71%and-6.7%,respectively.Technological progress had become the main factor in the growth of flue-cured tobacco output,and the growth of flue-cured tobacco production in China had turned to the type of technological progress.Combined with the progress of flue-cured tobacco production technology,we put forward targeted policy suggestions,in order to further tap the production potential of flue-cured tobacco in China and further enhanced the contribution rate of scientific and technological progress.
