Salt is one of the most important substances for human survival, and it is also the most commonly used seasoning in cooking. In recent years, with the tightening of the supervision system of salt industry, the number of patent applications for salt industry in China has gradually declined. In 20021year, the number of salt patent applications in China was 826, which was 22.37% lower than that in 2020.
Development status: production and demand rebounded, and export volume continued to increase. With the development of China's social economy, China's salt-making technology has made great progress, and the salt output has been greatly improved.
In 2020, affected by the epidemic situation, the output decreased slightly, and 202 1 rose somewhat. In 20021year, China's salt production was about122.73 million tons, an increase of 1.99% compared with 2020. In 20021year, the apparent demand for salt in China was116.75 million tons, an increase of 1.09% compared with 2020.
Reasons for grabbing salt in many places:
1. Rumors cause panic: In some cases, the network and the media will spread the news of the shortage of salt supply, causing people to panic and snap up. Even if there is no substantial salt shortage, panic will lead to snapping up.
2. Unbalanced supply and demand in different regions: China has a vast territory and a large population, and there are differences between supply and demand of salt in different regions. In some cases, some areas may be in short supply, while others may be in excess supply.
3. Storage and distribution: Problems in salt storage and distribution may also lead to supply shortages. During the peak period, the logistics distribution system may be under pressure, resulting in untimely supply.
4. Lack of understanding of salt substitutes: Because salt is indispensable in people's daily life, lack of understanding of substitutes may lead to people's excessive dependence on salt. Once there is a supply problem, people will snap up.
