中文摘要:
      农户生计能力存量的积累由量变达到质变的关键因素在于寻找生计能力临界点,即农户生计能力积累需要达到一定存量才能促进农户摆脱持续性贫困束缚,由此对应出现“高能、低贫”与“低能、高贫”两种匹配结果。利用陕西省贫困地区微观数据,考察生计能力对农户持续性贫困门槛值的影响。结果发现:在不同的门槛值下,生计能力总指数和各个维度与农户持续性贫困之间存在显著的非线性关系,即存在明显的“门槛效应”。通过门槛回归检验,社会资本、金融资本、人力资本、物质资本和自然资本与农户贫困持续性的门槛值为0.696、0.763、0.808、0.611和0.235,生计能力与农户贫困持续性的门槛值为0.622。当农户生计能力存量跨过一定“门槛”值后,生计能力才会显著的降低农户持续性贫困时间,生计能力对农户持续性贫困产生显著的负向影响逐渐增强。此外,社会资本、金融资本、人力资本和物质资本相互作用才能跨过门槛值显著降低农户持续性贫困时间。
英文摘要:
      The key factor for the success of the qualitative change in the accumulation of farmers’ livelihood capacity is to find the critical point of their livelihood capacity,that is,the accumulation of farmers’ livelihood capacity needs to reach a certain amount to stimulate farmers to get rid of the constraints of sustained poverty,which corresponds to the matching results of "high-energy/low-poverty" and "low-energy/high-poverty".Using micro-data of poverty-stricken areas in Shaanxi Province,this paper investigates the impact of livelihood capacity on the threshold of sustained poverty of farmers.The results show that under different thresholds,there is a significant non-linear relationship between the total index and each dimension of livelihood capacity and farmers’ persistent poverty,that is,there is an obvious "threshold effect".The result of the threshold regression test demonstrates that the threshold values of social capital,financial capital,human capital,material capital and natural capital and poverty sustainability of farmers are 0.696,0.763,0.808,0.611 and 0.235 respectively and the threshold values of livelihood capacity and poverty sustainability of farmers are 0.622.When the accumulation of farmers’ livelihood ability exceeds a certain threshold value,the livelihood ability will significantly reduce the duration of farmers’ persistent poverty,and the negative impact of livelihood ability on farmers’ persistent poverty will gradually increase.In addition,the interaction of social capital,financial capital,human capital and material capital can significantly reduce the duration of farmers’ persistent poverty.
