摘要: |
基于江苏省东海、射阳、滨海、泰兴四县的农户微观调查数据,将养殖户参与的生猪产业组织模式分为完全市场交易模式、横向一体化模式、订单养殖模式和纵向一体化模式,通过测度生猪价格波动和农户抵御市场风险能力,运用两阶段多元Logistic模型修正样本选择性偏误和内生性问题,实证分析了生猪市场价格波动对于农户的产业组织模式选择行为以及生猪养殖收入的影响。研究结果表明:价格波动是农户产业组织模式选择行为的重要影响因素,加入生猪产业组织虽然能够提高农户养殖收入,但市场价格波动幅度的增大会削弱产业组织模式带来的积极影响,使得农户加入产业组织模式的收入效应减弱,抵御市场风险能力较强的农户倾向于选择完全市场交易模式,倾向于不选择加入纵向一体化产业组织。 |

Abstract: |
Based on the survey data of pig farmers in Jiangsu Province, the pig industry organization models participated by farmers was classified into complete market transaction model, horizontal integration model, order farming model and vertical integration model. By measuring the fluctuation of pig price and farmers'' ability to resist market risk, using two-stage multivariate logistic model to correct sample selection errors and endogenous problems, this paper empirically analyzed the impact of pig price fluctuation on farmers'' choice of industrial organization mode and pig breeding income. The results show that price fluctuation is an important factor affecting farmers'' behavior of choosing industrial organization mode. Although joining pig industry organization can improve farmers'' income, the increase of price fluctuation will weaken the positive impact of industrial organization mode and weaken the income effect of farmers'' joining industrial organization mode. At this time, farmers with strong risk resistance tend to choose the complete market transaction mode and tend not to join the vertical integrated industrial organization. |
