Three questions about price subsidy

CPI rose 4.4% per cent year-on-year in October, according to statistics published by the National Bureau of Statistics.　　Rising prices have put pressure on the lives of difficult groups. Yesterday, the People's Daily published the article "How to supplement the price subsidy," throw three questions: price subsidy, who should supply? How much does it cost?　　Can it be long-lasting? The article said that the long-term resident in the local population, especially migrant workers can not always be excluded from public policy.　　At the same time, it is a basic principle of price subsidy that the quality of life of the disadvantaged groups can not be reduced because of the rising prices. With regard to its long-acting type, such as in Guangzhou, the distribution of price subsidy and the adjustment of the minimum living standard will form a long-term mechanism. If the low income consumer price index rises to 4%, and lasts 6 months, then consider directly raise the minimum standard.
