The objectives of this research are to propose a model for estimating and detecting rice yields in Thailand to investigate the factors related to the rice yields to find the trend and to construct the maps of rice yields in Thailand. A linear mixed model (LMM) including the spatial effects which follow the conditional autoregressive model (CAR) and the time effects which follow the first-order linear autoregressive (AR(1)) model is proposed. The estimated rice yields are used to construct the rice yield maps in Thailand. The dependent variables are the rice yield in each month of each province. The factors considered are rainfall average temperatures and regions. The results indicate that the factors enfluencing the rice yields are rainfall average temperatures and regions (North Northeast South East West Central region is a refrence region). The trend also effects the rice yields. The rice yeilds maps are easy for readers to identify which areas have high or low yields and easy to compare the yields among areas by looking at their different colors.

Thailand is on the way toward ASEAN Economic Community or AEC in the year 2015. The AEC aims to create one-solid base for production and distribution and concurrently seek mutual economical profits. A kind of business that may allow Thai entrepreneur to survive more easily in ASEAN is the selling and purchasing of goods and services via internet or ‘E-commerce’.

The samples of our study are the group of E-commerce’s entrepreneurs who legitimately registered with Department of Business Development. Our research revealed that the major factors that influence the development of E-commerce is the knowledge in foreign language which is considered to be the source of major advantage for business with average at 3.9750. Follow by the opening of free trade area which will cause more obstacles in term of the increasing number of competitor with average at 3.8475.
