| The existing researches on agglomeration economy are mainly restricted within an industrial level or regional economy level examination, and there is little analysis of organizational level. First, this paper follows the interdisciplinary tradition of regional science and introduces a new concept: the coevolution of organizations, which originally comes from biology and computer science. Basing on this new framework, we first examine the organizational interaction within agglomeration economy. And then we try to answer two questions which are logically related: (1) what is the mechanism on which the existence and evolutionary dynamics of agglomeration depend? (2) If there was the inertia of agglomeration, with a view of normative economics, is every kind of agglomeration desirable and efficiency-enhancing? Incorporating both microeconomic and macroeconomic analysis, we give answers to these questions.First, the analysis shows that in regional economy, organizations coexist in a dynamic process of coevolution and they learn from each other. In this process, an ambidextrous organizational structure is extremely important. The coevolution of organizations facilitates the efficiency improvement of institutions and structures. And it is exactly the inter-organizational learning provides the momentum of evolution and development. As a logical transition concept, we then introduce the inertia of agglomeration and our analysis turns to a normative analysis on agglomeration. As the basis, we provide a two-region economic model first. The model is designed to analyze the relationship between public investment and agglomeration. It indicates that unbalanced public investment policy may lead to self-defeating agglomeration, which is highly possible among complementary industrial regions. Other similar industrial policies may also have such kind of influence. This result is valuable to economic policy-makers, especially when the issues concern about the interregional policy coordination. |
