| Abstract: |
| The change of food production areas is the core issue related to food security. Many scholars at home and abroad have done a lot of researches on it. By sorting relevant domestic and foreign literature, this paper summarizes the main research results with the following characteristics:（1）paying attention to the spatial data statistics of grain production, and gradually applying the spatial regression model, which can avoid the correlation of dependent variables or omission of variables and rectify the research of common regression model;（2）the researches are extended from the theoretical level to the practical application level, the research areas are gradually reduced from the national and provincial levels to the city and county levels, and the researches on the influencing factors also start to change from the multi-factor comprehensive analysis to the single factor analysis, and the depth and practical significance of the research results are improved. At the same time, there are some shortcomings, such as more attention is paid to the macro, the general and the static state researches while less attention paid the micro, the special and the static state researches. Some suggestions are put forward for further researches on the change of grain production areas, such as the refinement of research perspective, the endogenous consideration of regression analysis, and the geographical heterogeneity in spatial measurement. |
