In the past twenty years, the American pig industry has experienced the process of large-scale farming replacing retail farming. According to the analysis of insiders, the basic situation of pig industry in China and the United States is similar, and the most important difference is that China lacks a set of hedging tools of pig futures.

American pig industry has a history of one hundred years, and it took about 20 years from 1980 to large-scale development in 2000. In the 1980s, there were about 670,000 pig farms in the United States, but in 2008, the number dropped to about 65,000. This is also the process of large-scale farming replacing retail farming, during which super pig farms were born. In 2008, the top 20 pig breeding enterprises provided more than 50% of the supply in the US market, while the supply share of the first enterprise accounted for 65,438+08% in the US. From 65,438+0,990 to 2000, its sales revenue increased five times and its share price increased nine times. American pig prices have also experienced ups and downs, but the company's share price has not been affected by this.

There are three driving factors for large-scale farming in the United States in the past 20 years: first, the promotion of contract farming model, similar to China's company plus farmers; Second, the pig futures varieties listed in the United States provide financial weapons for hedging and price discovery for the industry; Third, the agricultural population in the United States has greatly decreased.
