Based  on  the  framework,  we  define  the  operation 
matrix.  Using  the  method  of  DSM  matrix,  the 
quantitative  correlation  between  operation  control 
and  management  accounting  tools,  the  quantitative 
correlation  among  management  accounting  tools 
were  determined. The  case study  of  China  Unicom 
validates the central role of comprehensive budgeting 
in  enterprise  operations  management.  The  research 
results  reveal  the  significant  correlation  and 
hierarchical features among management accounting 
tools.  Firstly,  management  accounting  tools  are 
hierarchical  in  nature  according to  the  relevance of 
operational characteristics, and each hierarchical tool 
cooperates with and complements each other and has 
hierarchical  characteristics.  Secondly,  the  basic 
functions  of  management  accounting  tools  at 
different  levels  are  positioned  variably  with 
quantitative  intrinsic  relationships  with  each  other. 
Thirdly, the management accounting practice  based 
on the operational dimension is the process of deeply 
promoting the integration of business and finance. 
2  LITERATURE REVIEW   
Existing  research  puts  forward  management 
accounting framework including value management, 
balanced  scorecard,  comprehensive  budget  and 
activity-based  costing,  and  so  on.  With  the 
fundamental  goal  of  continuously  creating 
shareholder value, Serebryakova put forward a value 
management  framework  (VBM),  which  determines 
specific  internal  goals,  selecting  strategy  and 
organizational  design,  identifying  value  drivers, 
formulating action plans, and selecting performance 
indicators and goals, performance evaluation, as well 
as  feedback  improvement  (Serebryakova  2021). 
Pareek put forward a management framework based 
on the principle of the strategic management process, 
which  takes  the  Balanced  Scorecard  (BSC)  as  the 
core  and  integrates  tools  such  as  budget,  activity 
management,  and  shareholder  value  index  (Pareek 
2021).  Ploder  focused  on  the  combination  of  agile 
project  management  and  beyond  budgeting  (Ploder 
2020).  From  the  perspectives  of  economics, 
psychology, and sociology, Choi found imply that the 
patterns of budget ratcheting could be diverse based 
on  how  local  government  officials  strategically 
respond  to  the dynamics between  bargaining power 
and  the  pressure of justifying budgets (Choi 2021). 
The existing researches mainly discuss the influence 
of  specific  management  accounting  tools  such  as 
comprehensive budget, performance evaluation, and 
balanced  scorecard  on  specific  operational  control 
when  applying  the  management  accounting 
framework  to  operational  control.  For  example, 
Cools study the role of budgets in a creative context 
(Cools 2017). They find expected creative firms use 
their  budgets  in  a  more  interactive  way  and 
responsive creative firms use their budgets in a rather 
diagnostic way. Artz study the effect of performance 
measure  used  on  the  functional  strategic  decision. 
Lima  presents  the  results  of  the  strategic  planning 
process and the use of  the  Balanced Scorecard as  a 
strategic  management  system  for  the  Center  for 
Sustainable Development/Research Group on Energy 
Efficiency and Sustainability (Greens), University of 
Southern  Santa  Catarina  (Unisul)  (Lima  2021). 
Malagueño investigate the effect of BSC in SMEs on 
their financial performance and innovation outcomes 
(Malagueno 2018). 
An  appropriate  management  accounting  system 
depends  on  the  specific  environment  and 
organizational  structure  design  of  the  organization 
itself.  In  the  process  of  selecting  management 
accounting  tools,  enterprises  should deeply  analyze 
the  correlation  between  operational  control  and 
different  management  accounting  tools  and  the 
synergy  among  management  accounting  tools 
according  to  organizational  characteristics,  so  as  to 
ensure  that  the  selected  management  accounting 
toolset  can  effectively  connect  with  the  operational 
control mode of enterprises. As a result, it can give 
full play to the efficacy of management accounting, 
improve  the  level  of  enterprise  operational  control, 
and  then  promote  the  high-quality  development  of 
enterprises  by  building  a  management  accounting 
framework based on operational control. 
3  MANAGEMENT ACCOUNTING 
TOOLS 
The application  of management accounting  tools  in 
enterprises is to solve the management problems that 
restrict  the  ability  of  enterprise  value  creation. 
Therefore,  enterprises  should  not  only  consider  the 
internal  relationship  with  enterprise  operational 
control  but  also  consider  the  correlation  between 
management accounting tools when they implement 
management accounting tools. For quite a long period 
of  time,  the  common  topic  concerned  by  both  the 
practical  and  academic  circles  engaged  in  the 
research of management accounting is how to operate 
management  accounting  to  better  support  the 
operational control of  enterprises;  what are the  key 
elements  of  an  effective  management  accounting
