become  an  important  part  of  the  early  stage  of  the 
world  project  investment  decision-making.  Jean 
Durby,  a  French  engineer,  published  the  Utility 
Evaluation  of  Public Works  in  1844. Aiming  at  the 
problem  that  the  financial  analysis  method  cannot 
correctly  evaluate  the  economic  benefits  of  public 
utilities projects to the whole society, he proposed the 
concept  of  "consumer  surplus"  (Heralova  2017)  In 
1950,  the  United  States  published  the  Practical 
Method  for  Economic  Analysis  of  Inland  River 
Projects,  which  stipulated  the  principles  and 
procedures  for  studying  the  relationship  between 
benefits, cost ratio, project benefits and GDP .  
2  PEST ANALYTICAMETHODS 
PEST  analysis  method  is  a  basic  tool  for  strategic 
external environment analysis. It generally grasps the 
macro environment through the analysis of political, 
economic,  social  and  technological  factors  or  four 
aspects, and evaluates the impact of these factors on 
the  investment  environment  of  real  estate 
development enterprises (Reddy Sai Sravanth and N. 
Sundaram and Desti Kannaiah 2019) 
PEST Analysis was developed by Philip Kotler, a 
business  scholar,  marketing  guru,  and  professor  at 
Northwestern  University's  Kellogg  School  of 
Management.  "Trying  to  enter  a  market  without 
research  is  like  trying  to  enter  a  market  blindly," 
Kotler said in his book Kotler's Strategic Marketing. 
(
Peng and Nunes, 2007). It explains the importance of 
environmental analysis. 
To date, most successful businesses and products 
have been credited with taking advantage of changes 
and trends in the world. As the external environment 
changes, enterprises can  keep  pace  with  The  Times 
by  changing  their  business  and  products  to  survive 
(Murong Ren and Litian Wang 2020). PEST analysis 
is positioned as one of the frameworks to understand 
this  external  environment  (especially  the  macro 
environment) and to have an impact on the company. 
3  ANALYSIS OF PROJECT 
INVESTMENT ENVIRONMENT 
3.1  Overview of Beihai Real Estate 
Project 
Beihai City is a city famous for tourism. Taking the 
real estate project of Beihai City, Changsha Bay, as 
an example, it was carried out under the background 
of the COVID-19, when the tourism industry was hit. 
Analyzing the residential project of Changsha Bay, a 
Chinese port city, will help us understand whether the 
real  estate  project  of  the  tourist  city  in  the  post 
epidemic  era is feasible.  Beihai  Zhong  gang City  is 
located  on  both  sides of Shanghai Road and 
Chongqing  Road,  Henan  Road,  Haicheng  District, 
Beihai  City,  connecting  the old  city,  He pu  County 
and  Tie  shan  gang  District.  Surrounding  banks, 
markets, schools, hospitals and other facilities, Beihai 
Zhong gang City will stand at the height of the city, 
interpret the legend of the city with an international 
vision and vision, and build a new profile and skyline 
of Beihai.

3.2.1  Policy Environment Analysis 
2019  is  a  very  special  year.  On  December  29, 
COVID-19  began  to  break  out.  By  2020,  the  real 
estate market will be greatly affected by the spread of 
COVID-19.  In  the  first  half  of  2020,  the  central 
government  repeatedly  stressed  the  need  to 
strengthen  counter  cyclical  regulation,  maintain 
reasonable  and  sufficient  liquidity  in  the real  estate 
trading  market,  and ensure  employment,  livelihood, 
market, food security and supply chain stability in the 
"six stability" and "six guarantees"; Under the policy 
background  of  stabilizing  employment,  finance, 
foreign trade, investment and expectation, the overall 
financial  environment  pressure  of  the  real  estate 
industry  is  not  large.  At  the  same  time,  in  order  to 
fully release the domestic consumption potential, the 
government  has  increased  the  strength  of  the  new 
urbanization  and  regional  development  strategy.  At 
the same  time, it  has  delegated some land approval 
rights,  improved  the  market-oriented  allocation  of 
production factors, accelerated the transformation of 
old cities and dilapidated buildings, and promoted the 
long-term development of the real estate industry. In 
terms of real estate regulation, the central government 
still adheres  to the orientation  of  "no  speculation in 
housing, that is, no speculation in housing". Although 
under  the  macro  background  of  reasonable  and 
abundant  liquidity,  the  financial  supervision  of  the 
real  estate  industry  is  still  strict,  the  local 
government's policies on cities are more flexible, and 
many  places  have  introduced  real  estate  support 
policies from both supply and demand. Although the 
overall regulation situation has improved slightly, the 
government  still  adheres  to  the  determination  of
