农户专业化对农业低碳化的影响研究————来自北京市蔬菜种植户的证据

农户专业化和农业低碳化是农业现代化和农业可持续发展的必然环节,研究农户专业化对农业低碳化的影响具有重要意义.论文运用专业化分工理论和低碳经济理论分析了农户专业化对农业低碳化的影响.然后,根据2013年北京市蔬菜种植户的实地调查数据,运用联立方程组模型的似不相关回归(SUR)方法对理论分析结果进行了实证检验.结果表明:农户专业化与农业碳排放在5%的显著性水平上负相关,而农户专业化与农业产出和农业碳生产率均在1%的显著性水平上正相关.理论分析结果得到了经验验证,说明农户专业化对农业低碳化具有显著的正向影响.

Study on the Effect of Farm Households' Specializationon Low-carbon Agriculture: Evidence from Vegetable Growers in Beijing,China

It is of significance for studying on effect of households' specialization on low-carbon agriculture since the farm household' specialization and low-carbon agriculture are both important aspects of modern agriculture's sustainable development. Using specialization theory and low-carbon economic theory, this paper analyzed the effect of farm households' specialization on low-carbon agriculture. Then, according to the field survey data of vegetable growers in Beijing in 2013, simultaneous equations model and seemingly unrelated regressions (SUR) method were used to test the theoretical results. The findings show that the specialization of farm household is negatively correlated with agricultural carbon emissions at the 5% significance level, while it is positively correlated with both agriculture yields and agricultural carbon productivity at the 1% significance level. The result of theoretical analysis was proved empirically, which indicates that the specialization of farm household will be great beneficial to low-carbon agriculture.
