SHANGHAI government's efforts to upgrade and restructure industries have powered the city's manufacturing sector to lead in profitability and sales nationwide.

Its manufacturers enjoyed a profit margin of over 8.1 percent and achieved 100 percent in sales-output ratio in the first four months of the year, the Shanghai Commission of Economy and Information Technology said yesterday.

The city has upgraded its industrial structure with more advanced industries such as new energy and robotics. The output of new energy and robotics in Shanghai grew by double digits this year. The scale of Shanghai's integrated circuit industry has surpassed all other cities in China.
