Exploring the development and complements of the smart grid industry between Taiwan and China

At present, many countries devote a lot of resources to develop “smart grid”, including Taiwan and China. To establish a smart grid industry at the ground of the back-end management system, the most important subsystems are the smart meter, meter data management system, and energy information communication technology. This study mainly applied the industrial portfolio matrix composed with the industry life cycle and the industry value chain (industrial technology capability phase) to analyze the subsystem industries and its positions. Analysis results showed that the two sides have significant development in the smart meter subsystem industry, however, not in the other two, meter data management system and energy information communication technology subsystems. It proves that the two sides are still in the initial stage in the two subsystem industries.
