Group Decision Maldng And Spatio-Temporal Dynamics Of Migration

Human behaviors promote the development of society, and construct a colorful and interesting world. However, we know little about the mechanisms and laws of the dynamics of these social, technological and economic phenomenon. Therefore, the awareness and understanding of human beings has become one of the most challenging problem of the scientific community, especially quantitative description. The study of the laws of human behavior has a very important value for the study and application of economics, sociology and management. The development of complex science and the emergence of human dynamics impel people to explore human social behavior, and some remarkable achievements have been made. This paper committed to two types of typical human group behavior:product pricing process driven by the interests and the regional migration of population under the influence of natural factors. By a qualitative analysis of the two types of human behaviors and researched the question. Put forward the basic assumptions and establish a theoretical model to study the generation mechanism of these behaviors may affect the dynamics.Firstly, an evolution model is suggested to describe the correlation between the production and the price in an agricultural commodities market. The model highlights the decisions of two kinds of producers. One follows the trend of price to determine the production, and the other goes against the stream of price. The behavior of the market will be determined by decision-making behaviors of all individuals. The numerical results show the laws that govern the real markets. Especially, they demonstrate the relation between price and quantity of supply and/or demand, and also reflect that under different production backgrounds. The proportion of two kinds of producers will influence the trend of market prices and quantity of supply and demand. Compared with the situation in which supply exceeds demand, the market that is initially in the situation that demand exceeds supply can reach a balance under any proportion of two kinds of producers. This may reveal a basic fact that the situation that demand exceeds supply contribute to the producers to make the right choice. It can promote the market to develop well.Secondly, Combined with the theory of Push and Pull, establishing a regional population migration model to reflect the regional population and trend of per capita income. The model mainly considers the external influences that impact the population migration. Meanwhile, from the microscopic point of view, Considered one of the important reasons for the decision-makers of their own inherent temperament also affect migration. The simulated results show that the number of population migration law, such as the scale of the regional population migration and regional economic income gap present a positive correlation, the greater the gap between the level of income of the less developed regions and the systematic average income level, the larger the population to move out; The population migrated finally reached equalization of regional per capita income. In order to fully reveal the impact of migration on regional population size and per capita income, the model gives the space evolution pattern formation about the size of the population and per capita income. Regional income difference is the dynamic root of the population migration, and population migration is an important means of reducing regional income disparities.
