The boundaries of firms in the new economy: M&As as a strategic tool toward corporate technological diversification

Following the dynamic capabilities approach, we understand the recent wave of M&As as a corporate strategy mainly stimulated by the increasingly complex and uncertain techno-socio-economic environment in which firms operate. In this new situation, the boundaries of firms are in greater flux since firms are unable to develop individually all the competencies required to keep pace with the continual redefinition of business lines being driven by corporate competition. Using US patents granted to the world's largest firms, this paper analyses the dynamics of the sectoral specialisation of corporate technological profiles following large shocks that require some M&A deal. The findings of the analysis enable us to evaluate the adoption of M&As as a strategic tool to reshape corporate technological boundaries. On these grounds, we are able to identify patterns of technological diversification into strategic fields according to different models of industrial technological development.
