While the intensifying global food shortage has sounded the alarm for the food security of many countries in the world, international hot money has begun to accelerate its entry into the food industry. To this end, Cao Jianhai, director of the Investment and Market Research Office of the Institute of Industrial Economics of the Chinese Academy of Social Sciences, recently stated in an interview with the media: As the country with the largest population, largest food production and largest consumption in the world, China has inevitably become an international hot money The object of pursuit. In this regard, we should be more vigilant and guard against international hot money chasing China's grain industry. According to Cao Jianhai, since 2007, the sharp increase in domestic food prices and the national policy of increasing agricultural investment have begun to attract a large amount of capital to invest in agriculture, and the development of agriculture with "three capital" has become a social hot spot. International capital has also begun to covet Chinese agriculture. China's two largest dairy companies, Mengniu and Yili, have allowed foreign capital to gain a lot of benefits; after the international investment bank Goldman Sachs took control of Henan Shuanghui, China's largest slaughtering company, it has recently spent huge sums of money to acquire companies in China Pig farm. The entry of hot money into the grain market may have a greater effect on pushing up prices. If left unchecked, the agglomeration effect of hot money on the grain market will continue to rise. Therefore, he suggested that, first of all, with reference to international market prices, the purchase price of grain should be significantly increased to mobilize farmers' enthusiasm for growing grain. Secondly, moderately liberalize the export of domestic grain and its processed products. Third, strengthen the supervision of the grain futures market to prevent excessive trading, strengthen the management of grain purchases and sales outside the reserve department, and the inventory and sales prices of processing enterprises, and combat grain speculation. In addition, the foreign investment catalog will be adjusted to restrict and tighten foreign investment in agriculture and its upstream and downstream industries.
