Self-construction of farmers that implement assembly house will be given support in personal loan service or loan interest rate.

4. Tax benefit. Encourage and support enterprises, institutions of higher learning and research and development institutions to develop new technologies, technologies, materials and equipment for green building. The development of new technologies, new processes, new materials and new equipment for the development of green buildings can be paid for in accordance with relevant regulations of the state. support the qualified conditions shall declare the high-tech enterprises, and after the determination, they shall enjoy the corresponding preferential tax policies according to the regulations. For assembly building projects, the quality margin paid by the construction enterprise shall be deducted from the total contract price of the prefabricated component as the base multiplied by the 2% rate. The construction unit pays the residential property guarantee for the property construction installation total cost deduction prefabricated component total price as the base multiplied by the 2% rate plan. 

5. Encourage project application. construction area) does not account for the volume rate of the transaction block, which meets the commercial housing project required by the assembly building. At the same time satisfy the requirement of prefabricated construction and residential decoration commodity house project, prefabricated wall body part of the building area (not planning a total construction area of more than 5%) clinch a deal is not included in the plot of the volume rate calculation, the specific measures shall be separately formulated by the local governments; The building area that uses the wall insulation technology to increase is not included in the building area of the volume rate accounting; Residential buildings are used for heating and cooling of the ground source heat pump, and the heating and cooling system can carry out the electricity price of the residents peak valley.

6. Carry out project general contracting. The assembly construction project should adopt project general contracting mode with a integration in design, production and construction. An assembly building project that must be tendered in accordance with the law. Only a few of the construction enterprises that build industrial production can undertake construction, in accordance with the provisions permitted to use inviting tendering. An assembly building that requires a patent or a complete set of prefabricated construction techniques may not be tendered in accordance with the law according to  the regulations of the People's Republic of China on the implementation of the regulations.
