A newly established economic development zone was unveiled Monday and it's expected to rein in more efficient governance and provide better services for investors in what's described as the largest booming economic zone in northern China.

The new administrative district, Tianjin Binhai New Area, brings together the districts of Tanggu, Hangu and Dagang. It now spans 2,000 square kilometers and has a population of 2 million.

The State Council approved the plan in November.

The structure of management has now been simplified with the number of government departments slashed to just a quarter of what it was. Officials said this will significantly improve efficiency.

Binhai has three administrative districts and nine functional districts like the Tianjin Free Trade Zone.

"Binhai's internal administrative efficiency was low and the planning lacked overall coordination as each district was independent and had its own way," said Zhou Liqun, vice-president of the Binhai Development Institute of Nankai University.

There were seven public security bureaus, five industry and commerce administrations, six national tax bureaus, five local taxation bureaus and five procuratorates.

"The overlap led to redundant construction, inefficient allocation of resources and poor flow of land, capital and talent," said Lu Jun, an urban management expert at Peking University.

It's estimated that Binhai's total output value would increased 23.5 percent to pass 370 billion yuan ($54 billion) in 2009, accounting for about 54 percent of Tianjin's output, the People's Daily reported on its website.
