In China, urban land is classified as state-owned property. Companies, organizations and individuals can acquire the right to use state-owned land through allocation, leasing or mortgage.
The state possesses the authority to confer land use rights upon a land user for a designated period, either through public listing, auction or tender. In return, the land user is obligated to remit a land grant premium and execute a contract with the local administration bureau of land and resources. This agreement specifies various particulars such as the boundaries and area of the property, duration of usage rights, payment terms and premium amount, intended purpose for the utilization of said property as well as conditions for termination.
The maximum duration of industrial land use rights is 50 years, and the grant contract may be renewed, unless there are specific conditions or conflicts with the city's planning.
In accordance with the Notice on the Release and Implementation of the National Minimum Price Standards for Industrial Land Transfer (Guo Tu Zi Fa  No. 307), the minimum price for the transfer and the transaction price of industrial land shall not be lower than the benchmark land price corresponding to the land grade of the location. The industrial land within the scope of the Tianjin Port Free Trade Zone's Airport Economic Zone is classified as Grade 4, with a benchmark land price of 554 RMB per square meter and a plot ratio of 1.
