Dynamic Information Management System of Agricultural Economy Based on WebGIS This paper designs the dynamic information database of the agricultural economy, establishes a lightweight WebGIS based on JQuery, completes the general rendering engine of results, integrates the software architecture of MVC, combines the data encryption and the transmission technology, AJAX, the rich client development technology, the Mysql database and other Web development technologies, and develops the dynamic information system for agricultural economy based on WebGIS according to the agile development model. Through the dynamic information system of the agricultural economy, we can fully understand the utilization of the agricultural biological resources, and the types and distribution of the agricultural biological resources, so as to effectively improve the relationship between the agricultural biological resources and the local culture, society and economy, evaluate their utilization value, put forward the utilization strategies, and formulate strategies to promote the local economic development by using the agricultural biological resources.

System DynamicsBased Simulation of Ecommerce Industry of Ethnic Regions in China As the national strategic emerging industry, ecommerce industry is attracting more attentions. In order to deeply understand the dynamic mechanism of the Ecommerce industry development, this paper divides the ecommerce industry development system into four interrelated subsystems on the basis of system dynamics: technological progress, market demand, economic development and industrial environment. We construct the dynamic model of the Ecommerce industry system using MATLAB software, which is guided by the government, technological progress, logistics level. The market demand is variable to design different simulation policies. The corresponding countermeasures and suggestions are also discussed for the development of the ecommerce industry in ethnic regions in China.
