Abstract: In order to further reveal the internal connection between aggregation behavior and enterprise innovation, this paper combines agglomeration form with agglomeration scale to study the dynamic relationship among agglomeration form, agglomeration scale and enterprise innovation based on theories of innovation economics and agglomeration. It is found that the effects of agglomeration forms on enterprise innovation present a particular change trend according to different agglomeration scales: the effect of specialization agglomeration on enterprise innovation increases initially and decreases afterwards with the increase of agglomeration scale, presenting as an inverted U-shaped curve, while the effect of diversification agglomeration on enterprise innovation decreases initially and increases afterwards, presenting a U-shaped trend approximately. From the perspective of dynamic agglomeration scale, this paper provides a new explanation for how to promote enterprise innovation by the two forms of agglomeration.

Key words: enterprise innovation, agglomeration form, agglomeration scale, dynamic relationship
