基于生产要素贡献模型的南京郊县农业发展研究

Agricultural Development of Nanjing Suburban Counties based on Contribution Model of Production Factors

根据《南京市统计年鉴》中的数据,运用农业全要素贡献模型,对南京郊县农业生产要素贡献进行实证分析。结果表明,在面临劳动力、土地等生产资源约束的情况下,无论从农业总产值还是农业增加值来看,南京郊县农业已经进入"高投入-高产出"的阶段。在未来发展过程中,南京郊县应该优化农业投入要素的结构配置,以技术投入作为农业发展的主要动力,通过农业技术进步和技术效率的提升,实现农业的可持续增长发展。

According to data in Nanjing Statistical Yearbook,contribution made by agricultural production factors was analyzed with contribution models of agricultural factors and the results showed that with restriction of labor force and land,Nanjing suburban counties have entered into a stage of ＂high input-high output＂,considering no matter from agricultural total value of output or from agricultural added value.In future,structure configuration of agricultural input factors should be optimized in Nanjing suburban counties by technology input to improve agricultural technology and technical efficiency in order to further achieve sustainable development of agriculture.
