【摘要】：中国每年需从国外进口大量猪肉以供城乡居民消费,可以说这种现实状况容易对国家的粮食安全问题造成不利的影响,保障生猪养殖业的健康发展有利于保障食物安全。本文的数据跨度年限为2010-2013年,先从全国生猪出栏量和猪场数量的总量着手分析我国生猪养殖目前的发展水平,发现生猪散养仍在全国生猪养殖中一家独大,但与此同时规模养殖也在逐步发展,规模养殖的总体发展水平在不断提高,但内部里不同的规模养殖不平衡分化较大。而后对我国东部、中部、西部以及东北地区等四个不同养殖区域的描述性统计分析里,发现大体上的变动方向为由东往西,由南往北,由经济发达地区向经济落后的偏远地区转移;接着再从省际的角度出发,测算了集中度系数以及生猪主产省区,结果显示我国生猪养殖的省际集中度低,主产区主要是分布在四川盆地、长江中下游平原、黄淮流域的若干省份;此外,养猪传统、环境规制、市场条件、交通条件、价格等五个影响影响因素接受了计量模型的检验,得到显著的结果;根据研究提出科学协调行业内部结构,掌握区域移动规律,提高生猪养殖的集中度和集约化水平等建议。
[Abstract]:China needs to import a large amount of pork from abroad every year for the consumption of urban and rural residents. This reality can be said to have an adverse impact on the country's food security problem. The data span of this paper is from 2010 to 2013. Firstly, the current development level of pig breeding in China is analyzed from the total number of live pigs in China and the total number of pig farms. It is found that the bulk breeding of live pigs is still the only one in the whole country, but at the same time, the scale breeding is also developing step by step, and the overall development level of large-scale farming is constantly improving. However, there is a large imbalance in the internal culture of different scales. Then, in the descriptive statistical analysis of four different breeding regions in eastern, central, western and northeast China, it is found that the direction of change in general is from east to west. From the south to the north, from the economically developed areas to the economically backward remote areas, then from the angle of the provinces, the concentration coefficient and the main pig producing areas are calculated. The results show that the inter-provincial concentration of pig breeding in China is low. The main production areas are mainly distributed in several provinces in the Sichuan Basin, the plain of the middle and lower reaches of the Yangtze River, and the Huanghuai basin. In addition, five influencing factors, such as pig raising tradition, environmental regulation, market conditions, traffic conditions and prices, have been tested by the metrological model. According to the research, some suggestions are put forward to coordinate the internal structure of the industry scientifically, master the law of regional movement, and improve the concentration and intensive level of pig breeding.
