Abstract： Abstract: China implemented the policy of reform and opening up at the end of 1970s and gradually established the socialist market economic system with Chinese characteristics. China comprehensively introduced western economic theories, including macroeconomics. Western economics is based on the private ownership of capitalist means of production, without considering state-owned means of production. The government only plays the role of a night watchman. Directly applying western macroeconomic theory to study China's economic phenomenon can not deal with government-owned means of production and government investment issues. This leads to many problems in macroeconomic research today, especially in the field of fiscal policy. To solve these problems, we must consider China's socialist characteristics and reposition the dual role of the Chinese government in economic management: to provide optimal public goods and act as social planners to pursue maximum social welfare. In this way, many problems in current macroeconomic research in China can be solved.

Abstract： " In this paper we attempt to use some percentage of the profit of state-owned enterprises to balance the government pension budget. We construct the optimal contribution rate of the pension pooling account model. If the urban residents start with zero assets and finish with zero assets and only involve current urban employee, we find that all the profit of state-owned enterprises is not used for the budget balance of pension, the optimal contribution rate is 15.27%. If 10% of the profit of state-owned enterprises is used for the budget balance of pension, the optimal contribution rate can reach 13.67%, which is less than the existing contribution rate 16%. If all urban residents are insured, we find that all the profit of state-owned enterprises is not used for the budget balance of pension, the optimal contribution rate is 12.58%. If 10% of the profit of state-owned enterprises is used for the budget balance of pension, the optimal contribution rate can reach 11.04%. In addition, we also consider the retirement age is postponed, the contribution rate in 2050, and get the optimal pension contribution rate of the pension pooling account when different proportion of state-owned enterprise profits are used for pension payment. It can provide guidance for the improvement of our pension system.

Abstract： Infra-slow oscillation (ISO) is a kind of brain rhythm between 0.01 and 0.1 Hz. ISO is widely distributed in multiple brain regions. As an important brain activity, the ISO interacts with high-frequency neural rhythm via cross-frequency coupling while has different activity patterns from high-frequency neural activity. ISO may be generated by the dynamic activity of thalamus, glia and ions, regulating the overall excitability of the brain and thereby affecting the efficiency of cognitive activities. The frequency, amplitude, and phase of ISO could all regulate the overall efficiency of cognitive activity. Future researches should investigate the relationship between various physiological mechanisms of ISO and diverse cognitive activities, and explore the rules of the interaction between ISO and mental activities, further promoting the construction of rhythmic theory of brain function.
