Theoretically speaking, flood disaster will cause direct economic loss and indirect economic loss. The former is reflected in two aspects: one is to destroy the production of agriculture, forestry, animal husbandry and fishery, resulting in the loss of added value of the primary industry and, to a certain extent, affecting the current GDP growth rate; The second is the destruction of houses, roads, bridges, water conservancy equipment and other fixed assets, resulting in economic and property losses. However, this part of the loss affects the stock rather than the increment, so it will not affect the current economic growth.

As for the latter, it mainly shows that the flood has affected many links such as water and electricity supply, transportation and raw material supply, which has brought a little negative impact on industrial production. At the same time, due to the long-term rain weather, some infrastructure and real estate projects can not be started normally in the flood season, affecting the construction progress.
