Based on the Chinese national standardization status, this paper sets an evaluation system of national standardization on the principles of logic, comprehensiveness and operability, taking into account national standards and standardization activities. The evaluation system evaluates the national standardization development level through four aspects: standard development, standards implementation, standardization supporting measures, and participation in international standardization. This evaluation system provides a reasonable basis to evaluate the national standardization development level. The survey shows that if China wants to enhance its standardization development level, China needs to improve its standard development level, strengthen implication and application of standards, expand the standardization support measures and continuously improve the level of participation in international standardization.展开更多
