考虑到作为构成创新体系主体的企业的经济特性,因此基于市场因素而不是社会因素来研究企业间协同创新知识共享意愿不足是破解协同创新困境的根本性途径。首先,根据理性行为理论和动机理论,构建了市场因素(市场结构、市场初始需求、市场增长潜力)对企业间协同创新知识共享意愿影响传导模型。其次,以协同创新收益分配比例作为市场结构的替代变量,基于需求函数,将传导模型转化为数理优化模型。结果表明：(1)竞争性市场结构下,市场初始需求量与企业间协同创新知识共享意愿之间呈现“U”型关系；而在垄断性结构下,两者之间则呈倒“U”型关系。(2)竞争性市场结构下,如果初始市场需求量也较小,那么市场增长潜力与共享意愿之间呈负相关关系,否则为正相关；而在垄断性结构下,如果初始市场需求量较小,则两者呈正相关关系,否则为负相关。

Considering the economic characteristics of firms which act as the main body of innovation system, the fundamental way to solve the dilemma of collaborative innovation is to study the lack of willingness to share knowledge of collaborative innovation among firms based on market factors rather than social factors. Firstly, according to the theory of rational behavior and motivation, the conduction model is constructed, which reflects the influence of market factors (market structure, initial market demand, market growth potential) on the willingness to share knowledge of collaborative innovation among firms. Secondly, the allocation ratio of synergistic innovation revenue is used as an alternative variable of market structure. Based on the demand function, the conduction model is transformed into a mathematical optimization model. The results show that: (1) under competitive market structure, there is a U-shaped relationship between initial market demand and the willingness of knowledge sharing in collaborative innovation among firms, while under monopolistic structure, there is an inverted U-shaped relationship between the two. (2) under competitive market structure, if the initial market demand is small, the market growth potential is negatively correlated with the willingness to share, otherwise it is positively correlated; under monopolistic structure, if the initial market demand is small, it is positively correlated, otherwise it is negatively correlated.
