Three dimensional model: an analyzing sketch for e-commerce theories and applications

The sundry e-commerce related theoretic researches and practical application cases appear to have limitations in stressing the essence of e-commerce, depositing profound theories, and well guiding practices. Consequently, there still exists an urgent necessity for an integrated analyzing sketch of e-commerce. After clarifying such vital concepts like commerce (deal), commerce chain (deal chain), six flows, and application dimensions, the paper solves the problem through introducing a conceptual analyzing sketch: three dimensional model for e-commerce researches and applications. It then provides several sample expansions, deriving commerce chain based expansion, and commerce mode and commerce chain based expansion, and commerce chain and application dimension based expansion. Though the advancement has been the most significant contribution, detailed indexes designing may still require more efforts later.
