| China is in a critical period of building a moderately prosperous country, with indicators of people's health, nutritional status and life expectancy equaling with those of middle-income countries. As the hometown of soybeans, China is confronted with double challenges of under-nutrition in developing countries and nutrition surplus in developed countries. Research has proven that soy is not only a high quality protein, but can replace part of animal protein in the diet. Furthermore, its ingredients such as dietary fiber, Isoflavone is helpful to health. Therefore, we must coordinate soybean production, consumption and residents'nutrition and health in order to change the developing mode of soy industry and improve people's nutrition level and health status. Since the contradiction among soy production, consumption and nutrition improvement, research about soy industry based on the nutrition and health enhance means a lot. It is good to establish a nutrition-oriented consumption mode and a production model guided by consumption. All in all, it can encourage the rational use of soybean and its supply-demand balance to ensure the safety of soybean industry, which is of an important practical significance.Based on reference to a large number of researches at home and abroad, the paper examines soybean production and distribution, import and export, consumption of soybean and its products, industry competition structure and policy evolution with the application of nutritional balance theory, comparative advantage and industrial competitiveness theory,etc. Chinese soy industry is faced with many problems, such as the low-income of soy production, the large gap between soy industry in China and those of other leading soy producing countries, lack of competitive advantage, imbalance among soy products consumption, shortage of soy protein products and so on. All of these resulted in the fact that China's soybean industry is facing a serious crisis and the industry chain is shrinking severely. In the research of soy and nutrient relation in the paper, many calculating ways are referred and two basic conversion factors are put up with. Meanwhile, the paper predicts the per capita soy demand and overall soy demand amount in 2010, 2020 and 2030 respectively. Based on the analysis on differences between the actual per capita intake of soy and the recommended amount, it is obvious that the soy products consumption in China is yet to satisfy actual need according the reasonable dietary pagoda, although progressive increase was shown in the residents'soy intake in the past 20 years.Based on previous analysis, the paper moves on to the necessity and feasibility of developing soy industry aimed at improving people'nutrition and health level. It shows that since the imported gene-modified and high-oil soybean is inferior to domestic soy in terms of soy food production, its substitution elasticity is quite small to China's non-genetically modified and high-protein soybean. In this case, we should take full advantage of nutrition superiority of domestic soy and implement differentiation strategy in the direction of nutrition and health, which can bring considerate market interest.Aimed at nutrition and health improvement, cooperations should focus on the development of emerging soy food industry with great potential; give priority to the green and high-quality soy and its products, and accelerate the industrialization pace of traditional soy food. In the meantime, the government should increase subsidies to soy farmers, change the production structure, support the growth of potential leading soybean enterprises, strengthen technological advantage of China's non-genetically modified soybeans, enhance degree of soybean production and export organization, reinforce the soybean business credit services, foster the futures market of soybean and other agricultural products, in order to help soy industry become competitive and restore its advantage in soybean cultivation, processing and export. |
