Liu Shijin, deputy director of the 13th Chinese People's Political Consultative Conference Economic Commission and former deputy director of the the State Council Development Research Center, pointed out in his speech at the main forum of the 2024 Southern Finance and Economics International Forum that the macro-economy is picking up, but it is also facing the increasing pressure of insufficient total demand, especially insufficient consumer demand, and the focus of which is insufficient service consumption. We should give priority to improving basic public services and the consumption environment of low-and middle-income groups through "source governance" to promote the integrated development of urban and rural areas. On the basis of short-term stimulus policies, combined with medium-and long-term reforms, we will solve the institutional problems that restrict the expansion of consumption and help China's economy achieve high-quality development. "At present, it is necessary to distinguish the problems caused by insufficient demand from the causes of insufficient demand." Liu Shijin pointed out that from the perspective of international comparison, the lack of consumption demand in China at this stage is a structural deviation. In Liu Shijin's view, it is necessary to identify the key points or pain points in expanding consumer demand at this stage. First, service consumption based on basic public services, including education, medical and health care, affordable housing, social security, culture, sports and entertainment, financial services, transportation and communication; Second, the middle and low-income class with migrant workers as the focus; Third, people-centered, urbanization and urban-rural integration.

According to the Reuters survey, most economists expect that US President-elect Trump will impose tariffs of less than 10% or not at all on goods imported from Britain next year, which will have little impact on the British economy. This is in stark contrast to a similar poll last month. Last month's polls showed that people were generally worried that the EU would be hit harder. Britain officially withdrew from the EU in 2020. Part of the reason why economists are more optimistic about Britain is that although one-fifth of Britain's total trade is with the United States, the proposed tariffs will focus on goods, and only one-third of Britain's exports are goods.Aviation Materials Co., Ltd. released the Procurement Project of Feasibility Study Report of Beijing Aviation Materials Research Institute Co., Ltd., and China Hangfa Online Mall released the Project of Feasibility Study Report of Beijing Aviation Materials Research Institute Co., Ltd..
