| Abstract | How does "+ Internet" convert to "Internet +"? What are the influencing factors and how to affect economic growth of this structure change process? In this paper, through the establishment of infra-marginal model in which connector plays an important role, we explore microscopic mechanism of the "+ Internet" to "Internet +" process, and thus reveals the macro-significance to economic growth of "Internet +". We find that: the role of content supplier and the function of connector are the instinct difference between "+ Internet" to "Internet +",value-creative connector gradually replaces the value-distribution connector under the function of connecting everything, user generating content, platform’s cluster distribution and community sharing mechanism, thus "Internet +" connect community replaces "+ Internet" one-way local connection and the content supplier becomes adhesion; only the efficiency of market transaction and the transaction efficiency of connection service itself are greater than threshold value (Zi ? Zi0 and ? ? ? 0) at the same time, "Internet +" cross-border community will come true; the higher of market transaction efficiency and connection services production efficiency, and the lower of the connection services learning cost, the easier of connector’s appearance, however the value creative-connector’s appearance and agglomeration depends on the production efficiency and learning costs of the content; "+ Internet" to "Internet +" also has the positive function of promoting the optimal allocation of labor, expanding the market capacity and improving the economic surplus and per capita income level generally. This paper not only provides a structured and dynamic vision for "Internet +" study, but also has realistic enlightenment value for the policy and application practice. |
