3  RESULTS AND DISCUSSION 
3.1  Evaluation of Scientific and 
Technological Innovation and 
Common Prosperity 
Figure  1  shows  the  development  level  of  scientific 
and technological innovation and common prosperity 
of 30 provinces from 2000 to 2019.The curve with the 
lightest  color  in  the  figure  represents  the 
corresponding  index of  each  province  in 2000,  and 
the corresponding curve color gradually deepens with 
the increase of years. 
 
Figure  1:  Scientific  and  technological  innovation  and 
common prosperity. 
It can be seen from Figure 1 (a) that the scientific 
and technological innovation level of each province 
increased  year  by  year  during  the  investigation 
period, and the innovation ability among regions was 
extremely uneven. The top 3 provinces in the level of 
scientific  and  technological  innovation  in  2019  are 
Beijing  (0.703),  Shanghai  (0.501)  and  Guangdong 
(0.469).  As  the  most  economically  developed 
provinces in China, these three places have sufficient 
innovation  resources  such  as  R&D  personnel  and 
R&D  funds;  Scientific  papers,  international  patents 
and other innovative achievements are relatively rich; 
The  momentum  of  innovation  in  finance, 
information,  science  and  technology  is  strong.  In 
addition,  from  2000  to  2019,  the  level  of  scientific 
and  technological  innovation  in  Guangdong, 
Zhejiang  and  Jiangsu  increased  greatly,  which  has 
relatively high development potential in the new era 
led by innovation. As can be seen from Figure 1 (b), 
the  common  prosperity  level  of  China's  provinces 
increased  year  by  year  from  2000  to  2019.Among 
them,  the  level  of  common  prosperity  in  Beijing, 
Shanghai, Zhejiang, Jiangsu and Tianjin is relatively 
high,  and  the  development  degree  of  common 
prosperity  in central and  western provinces such  as 
Chongqing, Shaanxi, Sichuan, Hunan and Hubei has 
increased  significantly  during  the  investigation 
period. It shows that the eastern coastal areas of China 
have  better  realized  the  concept  of  "development 
achievements  shared  by  the  people".  Due  to  the 
support  of  national  policies,  the  progress  of 
infrastructure construction in the central and western 
inland  areas  has  been  accelerated,  and  the  people's 
living standards have been greatly improved. 
3.2  Analysis on the Coupling and 
Coordination between Scientific 
and Technological Innovation and 
Common Prosperity 
Based  on  the  analysis  of  the  development  level  of 
scientific and technological innovation and common 
prosperity, the coupling coordination degree model is 
used  to  calculate  the  coupling  coordination 
dispatching,  and  analyze  the  coupling  coordination 
relationship between the two provinces from 2000 to 
2019.  The  specific  results  are  shown  in  Table  2. 
According  to  the  above  judgment  criteria,  at  the 
beginning  of  the  investigation  period,  the  coupling 
coordination  degree  between  scientific  and 
technological innovation  and common  prosperity  in 
most  provinces  belongs  to  antagonistic  type.  Over 
time, the running in provinces gradually increase. By 
2019,  Beijing  has  become  the  only  coordinated 
Province in China. 
In terms of spatial distribution, the coupling and 
coordination level of 30 provinces basically shows a 
distribution pattern of "high coastal and low inland", 
the  driving  effect  of  coastal  areas  is  gradually 
spreading to inland areas, and the spatial gap between 
regions is gradually narrowing; In terms of coupling 
types,  the  coupling  coordination  levels  of  30 
provinces  during  the  investigation  period  include 
"maladjustment  type",  "antagonism  type",  "running 
in  type",  "coupling  type"  and  "coordination  type". 
The  intermediate  state  of  coupling  coordination  is 
mainly "antagonism type" and "running in type", and 
the  overall  "football  type"  mode  of  "few  high-low 
provinces  and  more  intermediate  provinces"  is 
presented. High quality coupling coordination has not 
yet appeared in a large area. 
From the perspective of time distribution, in the 
past  two  decades,  the  number  of  provinces  with 
unbalanced  and  antagonistic  coupling  and 
coordination  between  scientific  and  technological
