在现有理论基础上，结合荷兰等国家的经验事实，本文提出了创新工资门槛假说：工资上涨促进生产率的提高，但存在门槛效应。基于Hansen提出的门槛回归模型，使用中国国有企业和“三资”企业省级面板数据证实了该假说的存在。结果表明，国有企业中，工资水平低于23012．16元的省份有6个，他们可能陷入“低工资一低创新”陷阱；工资水平处于创新最佳状态的省份有22个。“三资”企业中，7个省份的工资水平处于创新的最佳状态。在控制变量中，国内市场需求与生产率正相关。%Based on papers and empirical study on Netherlands and some other countries, this paper provides a hypothesis, rising wage promotes the productivity, as only as the wage strides threshold. Using Hansen＇s threshold model and the data of state-owned and state-holding enterprises and enterprises with Hong Kong, Macao, Taiwan and foreign funds, the hypothesis is confirmed. We find there are six provinces whose wage of state-owned and state-holding industrial enterprises is under 23012. 16 Yuan, and the provinces would be trapped in the low wage-low innovation state. While, there are 22 provinces which are under the optimal state of innovation. Furthermore, there are seven provinces whose industrial enterprises with Hong Kong, Macao, Taiwan and foreign funds stride the threshold of wage. Among control variables, domestic market demand is positive with the productivity.
