SOEs must be reformed in accordance with Xi Jinping Thought on Socialist Economy with Chinese characteristics for a new era, which is the fundamental basis for maintaining the nature and direction of reform for SOEs. Reforms must be built on the fundamental standpoint with people at the center, and aimed at emancipating, developing and protecting productive forces based on the principles of justice and fairness, which is also the direction for Chinese SOEs reform in the new era. Adherence to the public ownership of state-owned assets in the form of value and its market-oriented management in the form of use-value is not only the objective requirement of a production mode adapting to the growth of productive forces, but also the logic of SOEs reform in the new era. Meanwhile, SOEs need to highlight the top-level designs of governmental systems in the reform process, giving e ective play to the leading and guiding roles of Xi Jinping Thought on Socialist Economy with Chinese characteristics for a new era.展开更多

The EFFT's additivity property is proved and the eigenmode of EFFT is derived. As an application, we calculate the EFFT of the three-mode squeezed vacuum state.展开更多
