Xinhua News Agency, May 9, the CITIC Construction Research report said that the steady growth of domestic infrastructure is still the main line of macro policy, and there is a broad space for urban, transportation, and clean energy construction. Strong global demand for infrastructure, strong competitive advantage of China's infrastructure and new diplomatic relations have boosted China's infrastructure to go out to sea. The management of central construction enterprises has improved significantly, and the value is expected to be revalued. It is suggested to focus on low-valuation central enterprises and "Belt and Road Initiative" beneficiary enterprises. From the perspective of management quality, the management quality of central enterprises in construction countries is generally better, and the current PB valuation of central construction enterprises is in the range of 0.7x-1.2x, which is still undervalued.
