| Pig industry has always been an important part of animal husbandry.China’s pig industry is playing an important role in the world.China has always been a major producer and consumer of pork.In 2016,685 million 20 thousand pigs were sold in the country.At the end of 2016,there were 435 million 37 thousand pigs in the whole country.In 2016,the total output of pork was 52 million 991 thousand tons,accounting for 62% of the total meat output.However,facing the complicated situation of economic globalization,standardization of production and diversification of consumption,China’s pig industry still has some problems,such as low scale,low industrial efficiency,and increasingly prominent environmental pollution problems,which will undoubtedly impede the sustainable development of Chinese pig industry.Facing these increasingly prominent development problems,how to integrate the structure of the pig industry,optimize the behavior of the pig industry and improve the performance of the pig industry is the key to ensure the sustainable development of the industry.In recent years,the pig industry in Shenyang has developed rapidly.The scale of pig products and the degree of commercialization have been gradually improved.In 2017,there were 2 million 259 thousand pigs in Shenyang and 5 million 45 thousand,which were 4.15% and 4.04% higher than last year.The total output value of animal husbandry is 22 billion 270 million yuan,accounting for 41.4% of the total output value of agriculture,forestry,animal husbandry and fishery.Taking the "South pig North raising" as a turning point,the large scale pig production enterprise,which was led by Shenyang source Fengyuan Group and Kang Pingyong Xian Zhengda,was rapidly rising around Shenyang.But at the same time,we should be aware of the problem.The pig breeding in Shenyang is still based on small scale breeding,scattered distribution,low market concentration,low scientific and technological level,low breeding efficiency and aggravation of environmental pollution.The long-term existence of these problems seriously hinders the healthy development of the pig industry in Shenyang.Based on the classic SCP paradigm of industrial organization theory and drawing on a large number of related research results,this paper systematically analyzes and analyzes the pig industry in Shenyang.Through the analysis of the market structure of the pig industry,it is concluded that the pig industry in Shenyang is an atomistic market structure,the barriers to import and export are low,the degree of product differentiation is low and the homogeneity is high;the producers in the industry are the passive recipients of the price,and the enterprises adopt technological innovation and combine the vertical union according to their own conditions.By analyzing the market performance,we find that the downward trend of pig breeding benefits is obvious and the negative external effects are bigger.The last part puts forward constructive suggestions according to the deficiencies in the paper. |
