东莞市都市农业要素贡献研究

Research on the Contribution of Urban Agricultural Elements in Dongguan

随着城市化和工业化的快速推进,工业城市的农业发展急剧萎缩,如何振兴城市农业发展成为当前面临的重要问题。本文采用柯布-道格拉斯Cobb-Douglas生产函数(CD生产函数)和索洛余值法,从农业各投入要素增长率和贡献率角度出发,以东莞市为实证对象进行都市农业路径研究。结果显示,科技进步对东莞市农业产出增长的贡献份额为71.80%,物质费用贡献率占重要份额,劳动力和土地的贡献份额较小,甚至为负值。因此,科技进步和设施农业可成为工业城市农业增长的主要选择。

With the rapid development of industrialization and urbanization, the agricultural development of industrial cities had shrunk dramatically, how to boost the development of urban agriculture had became an important issue. The contribution of urban agricultural factors in Dongguan were studied from the perspective of growth and contribution rate of each agricultural input element by Cobb Douglas production function and Solow residual method. The results showed that scientific and technological progress contributed 71.80% to the agricultural growth of Dongguan, the material cost still play an important role of agricultural growth, the contribution of labor and land were small, even negative. The science and technology progress and agricultural facilities could become the important agricultural growth choice for industrial city.
