The reporter explored: optimizing the transaction structure, the second-hand housing has become a hot spot in the market. "After the recent new property market policy, especially the reduction of transaction tax burden such as value-added tax, the second-hand housing is particularly popular." A senior real estate agent manager in Jindaotian District, Luohu District, Shenzhen, told the reporter, "Take several shed-reformed communities here as an example. Recently, more than 20 second-hand houses can be sold in each community every month. The price is low, the house is new and the location belongs to the urban area, which is very suitable for those who just need to buy a home." According to the data of Shenzhen Zhongyuan Research Center, the unit price of second-hand houses in the range of 40,000 yuan to 60,000 yuan accounted for 32.1% in November, ranking first and the increase was the most obvious. The transaction of new houses with a "building age" of less than 10 years was the most active. The reporter found out that in the second-hand housing market in several key cities, the transactions of new second-hand houses with relatively new "building age" are more active. Take Tianhe Park, a plate with high popularity of second-hand houses in Guangzhou, as an example. According to shell data, 41 sets were sold in this plate in October, a significant increase of 127.8% from the previous month. According to Yan Yuejin, vice president of Shanghai Yiju Real Estate Research Institute, the adjustment of tax policy will accelerate the listing of second-hand houses and good houses, which in turn will help buyers subscribe for second-hand houses and large-sized houses, which will have a positive effect on optimizing the transaction structure of second-hand houses and boosting second-hand housing transactions.

A short-term survey in Reuters, Japan, found that Japanese manufacturers' business confidence deteriorated further in December due to concerns about US protectionist policies. The survey of 505 large Japanese non-financial enterprises showed that manufacturers' confidence index fell from 5 in November to -1 in December, which was the first time since last February, and the number of pessimists exceeded optimists for the first time in 10 months. The loss of business confidence may cast a shadow over the Bank of Japan's forecast. The Bank of Japan had previously predicted that a steady recovery driven by rising wages and consumption would help inflation reach the 2% target in a sustainable way and justify further interest rate hikes. Many manufacturing industries have reported that business confidence has declined. Among electronic machinery manufacturers, steel and non-ferrous metal manufacturers, pessimists far exceed optimists.
