On efficiency of integrative strategies among companies in US high-tech industry

摘要

Integration strategies are very important to the existence of businesses in globalised market. Most of the prior integration studies only considered the change of its own production efficiency without considering the change of the overall post-integration industry production efficiency. This study proposed the optimum efficiency model using data envelopment analysis (DEA) as the methodology. To do this, we took the analysis of US 20 high-tech industry as a practical application. We selected the capital expenditure, the sum of employees and R&D expense as input variables, and the net income and the technology strength of patent as output variables in 2007. This model can help firms in simulating the integrating results to predict the success of future integration.
