The Machinery Industrial Park (机械工业集中区) has automobile, engineering machinery and relevant accessory industries as its major tenants. As a modern machinery industrial park, it has a planned total area of 1,542.21 hectares and primarily includes the projects of Xiagong Industrial Park, Automobile Industrial Park, the Phase II project of the Machinery Industrial Park, Supporting Industrial Park and a residential district. 

Construction of the Xiagong Industrial Park began in December 2002. It is primarily designed for production of excavators, skid steer loaders, light-duty engineering machinery, forklifts, road-making machinery, engineering steel structures, and special-purpose automobiles. 

The Automobile Industrial Park dates from 2004 and  offers four functional zones, namely, a finished automobile manufacturing zone, an auto parts manufacturing zone, an R&D and administration center and a logistics zone. It includes 14 projects with a total investment of about four billion yuan ($608 million) and an anticipated annual output of about 20 billion yuan. The primary enterprises in the park include King Long United Automotive, Yuchai Engine, King Long Auto Body, and King Long Air Conditioning.

The park's Phase II project will have a total investment of about 4.8 billion yuan ($730 million) and an annual output of 12 billion yuan. It is primarily designed for the development of the following industries: medium-pressure oil cylinders, construction material machinery, electronic machinery, hydraulic oil pipes, high-pressure oil cylinders, high-pressure pumps and valves, wind electricity generating machinery, special-purpose automobiles and auto parts.

The Supporting Industrial Park is expected to attract enterprises which provide support for leading enterprises such as Xiagong and King Long.
