One interesting aspect of the emerging industry-wide information infrastructure not yet explicitly addressed is that two systems exist in parallel to one another, the government-imposed centralized e-bidding platform and the company-driven B2B platforms. While the government-imposed platform experienced, to some extent, a reduction in importance it...

There are three possible limitations to our study and its results. The first two concern the domain that we studied. It might be the case that our findings are specific to both the Chinese context and the pharmaceutical distribution industry. Specifically the first limitation related to China as a research site may seem to suggest a high degree of...

As described above, we have used two approaches to analyse our data, which we labelled a life cycle and a teleological approach. The life cycle approach is based on our previously published multi-level framework for studying the emergence of B2B e-commerce systems and the teleological approach is based on a bottom-up coding process.

Partly based on our findings, but also extrapolating our own ideas, we suggest that the 2020 Enterprise has the following three characteristics.

The study, which commenced in 2004 and is still ongoing, is supported by a research environment that we call a Learning Community (LC).
