For this purpose, the value chains are broken down uniformly into four value-added stages: systems manufacture, planning and installation, operation and maintenance, as well as system management.
The model results distinguish between one-time effects of regional value-added at the stage of planning and installation, and ongoing, annual value-added generation along the lifespan of RE at the stage of operation and maintenance as well as the stage of the RE system management.
Furthermore, this modeling approach allows for a detailed analysis of the distribution of the generated value-added along the various stages in terms of income, business profit, and regional taxes [23].
While the share of regional value-added at planning and investment stage differs sharply between Germany and Japan, the share from annual revenues that remains as value-added in the region during system operation is rather comparable across all RE technologies (21% ~ 33%).
While the potential for value-added and employment at the stage of system manufacture is significant at the national level, RE system and components manufacturing companies have to be located within the respective region to generate value-added for a region.
General concept of this project can also be adapted and further extent to the coordination and controlling of other stages of value-added chain.
Beckhoff builds its own sales and maintenance networks, relying little on dealers—unlike some of its non-German competitors.The next stage is "hybrid value-added", in which the product is an outcome that the customer wants rather than the good that produces it.
The results show that personal income accounts for the predominant share of regional value-added in both countries at investment stage, while the share of business profit and regional tax income is comparatively smaller in both countries.
Similar principles concluded based on these applied cases can also be used to other industrial environment or other stages of the value-added chain.
All prices are at 2008 2009 level (value-added tax excluded).
