| 中文摘要: |
| 基于VES 生产函数模型，利用2001—2013 年广州市蔬菜生产的成本收益数据，对资本、劳动的投入产出弹性和资本对劳动的替代弹性进行了实证分析。结果表明:资本的投入产出弹性系数为1.2641，劳动的投入产出弹性系数为-1.0750；蔬菜生产中，资本对劳动的替代弹性呈明显的上升趋势，既反映了农业雇工成本快速上升的过程，也说明资本对劳动的替代过程符合充分竞争环境下的一般原理。提出如下建议：发挥技术的核心作用，鼓励菜农广泛运用优良技术；促进种业科研在品种抗性、多样性、产业链配合等方面实现持续进步；促进土地流转，实现适度规模经营，提高蔬菜生产的规模效率。 |
| 英文摘要: |
| Based on VES production function model, with the vegetable production cost data from 2001 to 2013 in Guangzhou, the paper empirically analyzed the output elasticity of capital and labor, and the capital-labor elasticity of substitution. The results shoued that the coefficient of input -output elasticity of capital was 1.2641, the coefficient of input-output elasticity of labor was-1.0750. In the vegetable production, the capital-labor elasticity of substitution showed
a rising trend, not only reflected the rapid increase in agricultural employment cost, also showed that the substitution process was in accordance with the economic theory under a fully competitive environment. This article Dut forward the following recommendations: let the technology play key role, encourage the farmers to use widely good technology, improve the scientific research in seed industry to achieve sustained progress in resistance of varieties, diversity, integration with other aspects of the industry chain, promote land circulation to achieve moderate scale management and improve scale efficiency of vegetable production. |
