The purpose of this paper is attempt to build and test the model of consumer behavior, using data communication on the mobile phone. Despite the explosive growth of 2nd generation mobile system (GSM) and rapidly increasing number of consumers who use media (such as photos or access the website) and try to get information they want.
We adopt four dimensions to build the structural model of consumer behavior, including need for cognition, product attributes, price factors and purchase intention, and define them as unobserved variables in the LISERL. Finally, we perform relative strength in the Path analysis showing causal model.
For model analysis, there are two phase to implement as follows: Firstly, we use Confirmatory Factors Analysis (CFA) to explore the correlation between unobserved (latent) and observed variables. Secondly, the relative relations of four unobserved variables will be confirmed by identification, estimation, test and model-fitting in the Structural Equation Modeling (SEM). We expect that the model of consumer behavior will be appropriately inferred and explain to 3rd mobile communication (3G) in the future.
