Based on the examples of collaborative innovation of Changzhou Science and Education Town, property rights of innovation subjects are economically analyzed by using Barzel's theory of property rights.It reveals that minimal waste is the inner mechanism of collaborative innovation, and all knowledge transactions can be implemented based on the mixture of two mechanisms "contract" and "non-contract".Besides, it finds that transaction cost of collaborative innovation system shows an increasing trend with system change, and it finds that agglomeration of technology resources is in an equilibrium state with moderate scale, complementary function and relatively stable network structure, while "smorgasbord" type of science and technology resources agglomeration cannot stimulate the synergies.On this basis, the following five proposals are put forward, that is to deal with the relationship between collaborative innovation implementation scheme and system construction, to play a leading role of the government, to grasp the equilibrium of collaborative innovation system, to pay attention to the development of intellectual property rights and to implement the mixture of science and technology trading resources.%以常州科教城协同创新为例,运用巴泽尔产权理论对创新主体产权进行经济学分析,揭示最小化浪费是协同创新的内在动力机制,所有知识交易均可以依靠"契约"和"非契约"两种机制得以混合实施;发现协同创新在知识溢出的同时,系统交易成本随系统的不断演进呈递增趋势;认为科技资源集聚存在一个适度规模、功能互补和网络结构相对稳定的均衡状态,"大杂烩"式的科技资源集聚并不一定能够激发协同效应.在此基础上,提出处理好协同创新实施方案与制度建设的顺序关系、发挥政府主导推进与资源配置效用的调节作用、把握协同创新系统规模均衡、注重知识产权保护和开发、采用科技资源交易混合实施5大政策建议.
