摘要
结合烤烟实际,阐述了烤烟生产科技进步的内涵,并运用Cobb-Douglas生产函数模型,以我国1983-2007年烤烟生产的有关数据为例,测算了科技进步、生产要素等对烤烟生产的贡献率,分析了生产要素与烤烟产出的关系。结果表明,我国烤烟科技进步贡献率为57.55%,对烤烟产量呈正效应的影响因素依次是种植面积、劳动用工和交售价格,呈负效应的影响因素依次是气候变化和物质投入,土地生产率趋于平稳,资金投入生产率还不高,技术进步模式以节约劳动为主导方向。在此基础上提出了实现我国烤烟生产稳定发展的对策建议,即严格计划管理、推动科技进步、提高投入资金使用效率、利用现代装备水平、建立烟田保险机制等。
Cobb-Douglas production function model was exerted to calculate the contribution rate of science and technology advancement to flue-cured tobacco production and to analyze the relation between production factors and flue-cured tobacco output. Data was taken from China＇s flue-cured tobacco production during 1983 to 2007 period. Results show that the contribution rate of science and technology advancement to flue-cured tobacco production was 57.55%. Factors such as planting area,labor employment,and sales price had positive effects on flue-cured tobacco production,while factors such as climate change and material investment had negative effects. Land productivity tended to be steady,fund investment productivity was still not high,and the technique advancement mode depended on economical labor predominantly. Some countermeasures and suggestions on stable development of flue-cured tobacco production were proposed,i.e. planning management strictly,pushing science and technology advancement,enhancing the usage efficiency of fund investment,making good use of the modern equipment level,and building up farmland insurance mechanism.
