本文以产业结构进化理论、创新理论为理论基础,应用基于自主体的建模方法构建了一个具有微观基础及内生创新机制的产业进化模型,并在模型基础上对企业技术创新对产业结构优化的影响进行了分析。研究发现,1.过程创新更加有利于产业结构合理化。产品创新和过程创新规模的上升都使产业结构向更合理的方向演进。2.在产业结构高级化方面,过程创新更利于产业结构中非农产业增加值的增加,而产品创新对工业中重工业比例上升的推动作用非常明显。随着产品创新和过程创新规模的增加,产业结构中非农产业增加值比重都在上升,同时产品创新规模的上升促进了霍夫曼系数的明显下降。
Abstract
The paper uses the agent-based modeling method to build up a micro-founded industry evolution model with endogenous innovation mechanism and studies the enterprise technology innovation behaviors' impacts on the optimization of the industrial structure based on the theory of evolution of industrial structure and the innovation theory. The study finds out that: (1) Process innovation boosts the industry structure rationality. With bigger size, both product innovation and process innovation facilitate the rationality of industry structure; and (2) As to the upgrading of industry structure, process innovation is more beneficial to the increasing of non-agriculture share of GDP(NAGR), whereas product innovation promote the decreasing of Hoffmann Coefficient. With the scale rising, both process innovation and product innovation lead to the increasing of NAGR. At the same time the rising of product innovation scale promote the declining of Hoffmann Coefficient.
