free no matter how large; If there is more than one set,
tax shall be paid from the second set. If more than one
suite is not self occupied and has income, it can bear
the tax and prevent others from attaching the house to
the tax-free quota for tax avoidance.
For retirees, set the age threshold. For example,
those who exceed the retirement age (generally 60
years old) only have one set of housing, which is tax-
free no matter how large; If there is more than one set,
tax shall be paid from the second set. If more than one
suite is not self occupied and has income, it can bear
the tax and prevent others from attaching the house to
the tax-free quota for tax avoidance. For the
unmarried young house buyers whose children of
Guangzhou families buy houses for the first time in
adulthood, if the house purchase area exceeds 100m²,
Considering the large area of tax payable, the
implementation of the registered residence
registration fee reduction 50m² for such people, non
registered residence registration can enjoy 35m² fee
reduction; If the area is less than 100m²/ The
registered residence of the city can enjoy 40m² fee
reduction. Non registered residence registration can
enjoy 25m² fee reduction. The registered residence of
singletons has more than 100m². The reduced area is
50m ². The area of tax exemption for those who hold
the residence permit for talent introduction in
Guangzhou is 50m². The self owned houses built by
farmers on the homestead are temporarily exempted
from real estate tax.
3.2 Using GIS Technology to Simulate
the Expropriation Process
Based on the above analysis, GIS technology is used
to simulate the process of government collecting real
estate tax. Based on the survey results, some
Tianyuan streets are selected as tax areas. The
housing types in this area include class I residence
(Villa) and class II residence, and have many factors
affecting house prices, such as location, greening,
education, commerce and so on. After learning the
housing location information, the corresponding
record carrier is established through GIS system to
realize the visualization of spatial relationship. The
10 housing information is assumed and the ownership
is Guangzhou registered residence. The income
method is adopted for the appraisal. GIS assisted
appraisal predefines and calculates the mathematical
model according to the selected appraisal method to
provide the reference price of real estate. The free
area is only for the first house of the owner, and the
free area is not allowed from the second house.
The tax rate policy of five grades of excess
accumulation system is implemented for the taxable
area. The tax rate of 0.7% is adopted for the taxable
area of class I residence of 50m² - 100m², and 1.1%
is adopted for the taxable area of class II residence of
more than 90m² and less than 120 m².
4 RESEARCH CONCLUSION
Taking GIS as the main research tool, this study
selects representative blocks by using the data of
block population density, economic development
level and income level. At the same time, the
replacement rate of real estate tax on land transfer fee
is calculated by different tax rates and exempted areas
based on the data of permanent population and the
number of primary and secondary school degrees.
Referring to the implementation methods of the
current two pilot cities of real estate tax, simulate the
policy rules and policy combination, and finally
simulate the real estate tax collection process (Fan, et
al, 2010).
In addition to legal principles and respecting
historical traditions, the renewal and supplementary
payment of land use right also needs to be based on
economic principles, the concept of social equity and
the specific practice of land system (Huang, 2018).
Based on the land price theory, from the perspective
of land policy and public policy, land taxation and
social equity, and from the perspective of realizing
social fairness and justice, reducing management
costs and conforming to economic laws, China
should abandon the policy orientation of continuing
to pay the transfer fee according to the real-time
market rent when the land expires, and amend
relevant laws in time to make the use right of
residential land long-term or even permanent, and
adopt appropriate land tax policies to return the land
value-added income to the state (Chen, et al, 2007,
Zhu, 2016). The recovery of land appreciation should
become the main value orientation of China's land
policy in the future. Therefore, the three policies of
differentiated low standard collection, consolidated
real estate tax and land appreciation are more
reasonable, especially land appreciation (Zhu, Fang,
2019).
No matter when the land use right expires, in the
real estate transaction link, the evaluation institution
entrusted by the government will calculate the land
appreciation and recover 30% - 60% of the
appreciation. If the appreciation is not increased,
there is no need to make up the payment. The
supplementary payment of similar land value-added
