The government's increasing investment in infrastructure can usually bring social total demand and national income several times that of investment, which plays a "multiplier effect" in economics. In this regard, the "New Deal" is a model to help the unemployed by establishing infrastructure and public projects, which is obvious to all. At present, the lag of infrastructure construction is still a "bottleneck" restricting China's economic development. The impact of the Asian financial turmoil also makes it more urgent and necessary to ensure the sustained growth of the national economy by increasing domestic investment and domestic demand. We have many advantages in implementing this strategic measure: the savings balance of urban and rural residents is nearly 5 trillion yuan, the savings rate is much higher than that of other countries, there are more than180 billion yuan of foreign exchange reserves and foreign currency deposits, and there are trillions of yuan of cash and liquidity in the society; There are all kinds of stocks and overstocked materials of nearly 10 million yuan, with abundant grain reserves; State-owned collective enterprises in various parts of the country have factories, equipment and venues with assets of trillions of yuan, and there are blind construction, repeated investment projects and half-baked projects formed under the fragmented system. At the same time, China's abundant labor resources also urgently need to display their talents in these fields and open up new employment opportunities. According to the needs of economic growth and structural adjustment, the central government has taken some necessary measures to expand domestic demand and increase investment, and put forward a plan to increase government investment by 750 billion US dollars within three years. The urgent task is to strengthen the start-up of investment, concentrate all available funds to issue construction bonds to the society, build public projects such as farmland water conservancy, railways, highways, cultural and sports facilities in batches nationwide in a planned way, develop a number of labor-intensive industries with less investment and quick results, increase employment, raise the income level of all citizens, effectively stimulate rational consumption, promote production, and form "economic growth, wealth increase, income increase, income increase" as soon as possible.
