In 2022，in the face of pressures such as consumption contraction and external demand slowdown caused by the impact of unexpected factors at home and abroad，China will increase macro-control efforts in a timely manner and give full play to the key role of investment，achieving a growth rate of 5.1% throughout the year. The contribution rate of fixed asset investment to economic growth reached 50.1%，and the contribution rate was 1.5 percentage points. Among them，the growth rate of infrastructure was strong，the investment in manufacturing industry accelerated，and the investment in real estate development fell year-on-year. With the optimization of the epidemic policy，under the support of positive factors such as increasing fiscal efficiency and improving financial efficiency，precise and powerful finance，and improving market expectations，in the first quarter of 2023，fixed asset investment will recover strongly，and the key role in promoting economic improvement will continue to be released. It is recommended to focus on weak private investment willingness，intensified differentiation of investment growth，blindly launching inefficient and ineffective investment projects，and continuous recovery of real estate，continue to play and release the key role of investment in stabilizing the economy，and use effective investment to help the economy recover steadily and sustainable development.
