Concentration of industry at a high-end platform and intensive type of development is one of the important means of changing the mode of industrial development and restructuring in Qingdao, a coastal city of east China's Shandong province.

The output value of 50 Qingdao's industry agglomerations stood at 500 billion yuan (US$75.1 billion) in the first half of this year, which creates history's best record.

In the first half of this year, Qingdao redoubled efforts to recruit foreign investment and speeded up the construction of projects. Up to now, over 250 projects with the investment of over 100 million yuan have been signed, launched or started operation in these industry agglomerations.
