A team of officials from nine ministries and ministerial-level departments will be sent to Shanghai to investigate if austerity measures to rein in the city's red-hot property market have been implemented and taken effect. This follows a local government think-tank's warning of the risk of oversupply in the property market in the coming years. 'Relevant leaders' had agreed with the points put forward in a Shanghai Academy of Social Sciences research paper that was sent to the Ministry of Construction last summer, the 21st Century Business Herald reported on Friday. The paper warned of excessive development approvals for residential properties during the 10th Five-Year Programme (2001-2005), especially in the city's outskirts. The investigators would focus on a few main areas - whether central government control measures were in place, the state of property prices, idle land. demolitions and construction of low-cost housing - the newspaper said. The team will comprise officials from the construction, supervision, land and resource ministries, as well as from State Council-backed bodies such as the National Development and Reform Commission. Shanghai's surging property market has put housing beyond the reach of the masses and has proved difficult for Beijing to rein in. Investment in Shanghai residential property from 2001 to 2005 was double that of the previous five years. It cooled off in September last year, when Shanghai party secretary Chen Liangyu was sacked for misusing the city's 10 billion yuan social security fund. Immediately after Mr Chen's sacking, Zhu Wenjin , director of the Shanghai Housing and Land Administration's land-use management section, was arrested for accepting bribes in return for land approvals. The research paper shows that 74.4 per cent of the land approved from 2001 to 2005 was by agreement, a form more likely to involve corruption.
