摘要:

2013年4月的H7N9禽流感重创了中国的肉禽业,挫伤了大量养殖户的养殖信心。肉禽业的稳定发展离不开养殖户养殖信心的恢复。中国肉鸡产业化发展迅速,生产契约日益影响农户生产决策,同时肉鸡生产存在南北方地域差异。因此,探讨契约农业和地区差异对养殖信心恢复周期的影响具有实际意义。本文依托全国6个肉鸡生产大省280个肉鸡养殖户的调查数据,采用寿命表法、韦布尔分布函数和Cox比例风险回归模型研究发现,在正常情况下,全体养殖户预计到2017年12月能恢复养殖信心;参与契约农业的养殖户或来自北方的养殖户受H7N9事件的冲击较小,养殖信心恢复较快;养殖户参与契约农业的养殖信心恢复概率比未参与的高77%,南方养殖户比北方的信心恢复概率低89%。

Abstract:

The H7N9 avian influenza event in April 2013 damaged the meat poultry sector in China and resulted in a loss of farmer breeding confidence. Steady development of the meat poultry sector depends on breeding confidence recovery. Industrialization of the broiler industry is developing fast and contract farming has influenced farmer production decisions, and exposed differences in broilers farming between southern and northern China. It seems significant to investigate influence of contract farming and geographic differences in farmer breeding confidence rebound. Using 280 broiler farmer samples from six top broiler production provinces, life table methods and the weibull distribution function were used to study farmer farming confidence and predict rebound cycles. Secondly, cox proportional hazard regression model was used to analyze factors that influence breeding confidence rebound cycle. It was found that all farmers are expected to rebound their breeding confidence by December 2017 under normal circumstances. Farmers taking part in contract farming from northern China were less influenced and their breeding confidence recovered quickly. The breeding confidence probability of farmers who participated in contract farming was 77% higher than other farmers. The confidence probability of farmers from southern China was 89% lower than those from northern China. In terms of control variables, farmers who were male, had poultry breeding as their main business, had spent a few years farming, had a low proportion of farm income accounting for total family income, had not experienced avian influenza epidemics, and who had epidemic prevention information channels were more likely to recover breeding confidence quickly. Increasing public and professional epidemic prevention information channels, encourage farmers to participate in contract farming for market risk shift, improve and standardize the live poultry market in southern China may be better ways to hasten breeding confidence recovery.
