expenditure efficiency. The reason may be that the
higher the population density, the higher the public's
requirements for living conditions, which is condu-
cive to improving the efficiency of urban renewal fi-
nancial expenditure.
The regression coefficient of urbanization rate
(urban) to the efficiency of urban renewal financial
expenditure is significantly positive, which indicates
that the increase of urbanization rate can obviously
improve the efficiency of urban renewal financial ex-
penditure. On the one hand, the improvement of ur-
banization level means that a large number of rural
people gather in cities, resulting in scale effect,on the
other hand, with the gradual improvement of urban
spatial layout and functional structure, the relative en-
vironment of urban financial input and output be-
comes better, which is more conducive to the rational
allocation of urban financial resources by the govern-
ment and the promotion of urban financial expendi-
ture efficiency.
The regression coefficient of urban renewal finan-
cial investment scale (scale) to urban renewal finan-
cial expenditure efficiency is positive, indicating that
there is a positive relationship between them, but it is
not significant. It may be because the funds invested
in some areas have not been effectively allocated, and
there are unreasonable or wasteful phenomena, which
leads to low efficiency of financial expenditure.
Therefore, local governments should determine the
scale of financial investment in urban renewal accord-
ing to local conditions.
The regression coefficient of education level of
residents (edu) to the efficiency of urban renewal fi-
nancial expenditure is positive, indicating that there
is a positive relationship between them, but it is not
significant. Generally speaking, the higher the educa-
tion level of residents, the higher their support and en-
thusiasm for urban renewal, and they can play a better
role under the local reasonable public participation
mechanism of urban renewal. However, some urban
public participation mechanisms are imperfect, the
implementation effect is not in place, and they fail to
play an effective role, thus restricting the efficiency
of urban renewal financial expenditure to some ex-
tent.
5 CONCLUSIONS AND
SUGGESTIONS
According to the results of empirical analysis in this
paper, and by comparing the average calculation re-
sults of comprehensive efficiency, technical effi-
ciency and scale efficiency of cities in Liaoning prov-
ince during the whole research period, it can be seen
that there are significant differences among different
cities, and Shenyang, Benxi, Liaoyang, Yingkou and
Panjin are DEA efficient, meanwhile, they are both
technically efficient and scale efficient. The scale ef-
ficiency values of Dalian, Fuxin and Huludao are
lower than the technical efficiency values, which in-
dicates that the scale efficiency leads to the low level
of comprehensive efficiency in these cities, and the
investment scale should be adjusted reasonably. An-
shan, Fushun, Dandong, Jinzhou, Tieling and Chao-
yang have low comprehensive efficiency because the
technical efficiency is lower than the scale efficiency.
Therefore, should be made to adjust and improve the
government management structure or level. Through
further analysis of influencing factors, it is found that
urban population density and urbanization rate play a
significant role in promoting urban renewal, There is
a positive but not significant relationship between ur-
ban renewal financial investment scale and education
level of residents, while there is an insignificant neg-
ative relationship between regional economic devel-
opment level and urban renewal financial expenditure
efficiency. In view of this, this paper puts forward the
following countermeasures and suggestions:
Optimize the structure of government financial
expenditure and determine the scale of urban renewal
financial expenditure according to local conditions.
Give full play to the role of human capital and en-
courage the development of innovative and high-tech
enterprises.
Accelerate the formation of regional economic
layout with complementary advantages and high-
quality development, and promote the high-quality
development of cities.
