中文摘要：

利用中国区域经济发展不平衡的事实，假设工业部门面临的劳动力市场具有完全竞争性的条件下，其实际工资水平应当等于该部门劳动的边际生产力，并运用永续盘存法估计资本存量，通过实证分析估计工业部门生产函数和劳动的边际生产力，根据工业部门面临完全竞争的劳动力市场的一般性假设，推断出目前中国经济至少已经超越刘易斯第一拐点。

英文摘要：

In consideration of the regional economic disparity in China, this paper takes the developed provinces as a proxy of the industrial departments in the context of Lewis Ranis Fei Model of dual economies. The paper estimates the production function and the marginal product of labor for such an industrial department by use of regression and the perpetual inventory approach. The results show that the Chinese economy has surpassed the first Lewisian turning point at least.
