Shanghai aims to double output of strategic industries by 2015, according to the city's economic planning agency, even as a senior lawmaker cautioned that the city should be more selective over the industries to ensure there is no duplication with other provinces.

The State Council, China's Cabinet, in September identified seven emerging industries which include information technology, alternative energy and high-end equipment manufacturing industries.

Shanghai had earlier selected nine strategic high-tech sectors for development, which largely overlapped with the national plan.

Zhou Bo, director of the Shanghai Development and Reform Commission, yesterday said the city plans to raise the industrial output of these emerging industries to 1.07 trillion yuan (US$160.7 billion) by 2015 from 518.5 billion yuan last year and to boost service-related sales from 169.2 billion yuan in 2009 to 430 billion yuan in the period.

These industries could account for 30 percent of Shanghai's industrial sector by output value and 50 percent by fixed-asset investment, Zhou told delegates of the Shanghai People's Congress and National People's Congress.

But Liu Yungen, chairman of the Shanghai People's Congress, advised that the city should study carefully which segments to focus on as several provinces are also eying the same seven emerging industries under the national plan.

"We can see provinces also targeting the same industries, which may lead to a severe situation," Liu said. "For example, there is already severe overcapacity in photovoltaic and wind power equipment."
