Study on the Current Status of China’s Food Security Based on Multiple Dimensions Measurement

As a large agricultural country, food security is of vital importance to the national economy and people's livelihood. In recent years, food production has been constantly restricted in order to meet the needs of urbanization and economic development. And problems such as resource compression, cost increase and insufficient investment in science and technology have gradually surfaced. In order to guarantee the food production safety, this paper comprehensively analyzes the status of China's food security from four aspects: food availability, food access, food utilization and the stability of food security. Through comparative analysis, it is known that the overall situation of China's food security has been significantly improved. It is better than the average level of developing countries. China also has advantages when compared with other developing countries with large populations, but there is still a certain gap with the average level of developed countries. China's food security situation is not balanced in different dimensions. The food availability situation measured by indicators such as per capita food output and average dietary energy supply has significantly improved. The food access measured by per capita GDP, domestic food price index, prevalence of undernourishment and so on, enhances continuously. The global hunger index was significantly reduced in food utilization, and the condition of food utilization measured by clean drinking water sources and good sanitation facilities was significantly improved. The lower stability index of political stability, the higher domestic food price volatility and per capita food production variability are not conducive to the stability of food security.
