Knowledge sharing is the core of organizational knowledge management. How to measure and identify the organization’s knowledge sharing capability is a very important issue in knowledge sharing studies. Firstly, the concept of the organization’s knowledge sharing capability is presented, and the two dimensions, including technical and non-technical capability, which form the organization’s knowledge sharing capability, are analyzed. After that, the corresponding assessment criteria system is constructed based on these dimensions. Additionally, a measurement approach is proposed, and also, a matrix model is established to identify the organization’s knowledge sharing capability, by the model, the causes of formation and intensity for the capability can be analyzed. Finally an application is given to illustrate the practicability and validity of the approach proposed above.
