The employees in Chinese state-owned enterprises usually enjoy high-level staff welfare, which has not achieved the desired effects though. Especially, high-level staff welfare does not mean equivalent satisfaction. In this sense, it is feasible to investigate quantitatively the status of the staff welfare in Chinese state-owned enterprises and analyze its features and defects. A new welfare model is designed and improved in this paper to confirm that the employee welfare of state-owned enterprises in China is short of satisfaction. Its manifestations include low sense of fairness, low satisfaction with non-monetary welfares compared to that with monetary welfares, and low satisfaction with welfare capacities compared to that with welfare functions. To improve the welfare system in Chinese state-owned enterprises, it is essential that the equalization of welfare should be prevented, that the cost of welfare should be shared scientifically, and that the welfare capacities and welfare functions should be promoted.
