core of production safety measures. In the process of 
municipal  new-energy  safety,  fully  motivated 
employees  attach  great  attention  to  safety  problems 
and have much interest in seeking solutions. From the 
safety production results, the frequency and severity 
of accidents in companies with better implementation 
of safety incentives are highly  reduced. To  sum up, 
the  role  of  safety  incentive  in  enterprises  is  four 
aspects (Duan 2007). 
In order to achieve safe production of municipal 
new-energy  engineering  project  with  high  quality, 
enterprises  must  have  a  clear  driving  force  and 
constraints.  To  realize  this,  we  always  need  to 
introduce  incentive  mechanism  to  fully  arouse  the 
enthusiasm  and  subjective  initiative  of  each 
production  safety  practitioners,  that  is,  motivating 
employees  to  do  a  good  job  of  safety  by  means  of 
economic  and  administrative  strategies.  In  this 
respect, the realization of the goal for safe production 
is closely related to each person's economic interests. 
For  those  who  has  achieve  the  target,  they  will  get 
some rewards. While for those who fails to reach the 
target, they will  definitely get  a punishment. In this 
way,  incentive  intensity,  indicating  the  strength  of 
safety  performance  appraisal,  is  highly  vital  for 
bringing  about  safety  behaviors  consistent  with  the 
safety  production  goal  pursued  by  the  enterprise 
(Zhang 2015). Thus, in this work, a novel method is 
raised  based  on  motivation  theory  to  measure  the 
safety performance appraisal strength, which is aimed 
at  helping  to  promote  safety  management  and  stay 
away  from  disasters  throughout  the  new-energy 
enterprise. 
2  SAFETY PERFORMANCE 
ASSESSMENT SYSTEM AND 
INCENTIVE INTENSITY 
DIVISION 
2.1  Concept 
Safety  performance  assessment  refers  to  using 
scientific  standards,  methods  and  procedures  to 
evaluate  the  behaviours,  achievements  and  final 
actual performance of the organization, department or 
staff as accurately  as  possible. There  are  four  basic 
performance  appraisal  methods,  namely  key 
performance  indicators,  balanced  scorecard,  360-
degree  performance  appraisal  and  management  by 
objectives.  According  to  relevant  literature  review 
(Hu 2008), this paper defines safety performance as 
the combination of safety construction state and the 
final  consequences  of  safety  accidents.  The 
comprehensive results of contents of the  above  two 
can more completely and accurately reflect the state 
of enterprise safety performance. 
2.2  Safety Performance Appraisal 
System 
To  adopt  scientific  and  reasonable  evaluation 
methods  to  more  accurately  evaluate  the  safety 
performance of different enterprises, it is necessary to 
start  from  the  process  of  safety  production  and  the 
consequences  of  accidents.  In  the  whole  evaluation 
process,  the  safety  of  municipal  new-energy 
engineering projects is the key point emphasized by 
the  enterprise.  Reasonable  design,  control  and 
adjustment  of  the  safety  production  process  are 
necessary  means  of  realization.  Enterprise  safety 
performance  assessment  is  a  complete  operation 
process,  which  generally  should  include  five 
procedures,  that  is,  the  establishment  of  enterprise 
safety objectives and indicators, the determination of 
index  weight,  safety  production  performance 
evaluation, and the feedback of assessment results. 
When the process of safety performance assessment 
of  an enterprise  is completed,  it will proceed  to  the 
establishment  and  determination  of  enterprise 
objectives  in  the  next  stage,  thus  forming  an 
assessment cycle (Duan and Chen 2010). 
Based on the idea of strengthen source prevention, 
pay  attention  to  process  management  and  give 
consideration to result control, it makes the scope and 
nature  of  enterprise  safety  production  management 
work more clear, so that enterprises are able to take 
corresponding measures to prevent the occurrence of 
accidents  and  ensure  the  safety  production  (Sun 
2019). Considering the authority and universality of 
accident classification in China, we take the accident 
occurrence  degrees  (ordinary  accident,  larger 
accident, major accident and extraordinarily  serious 
accident),  which  belongs  to  the  category  of  result 
control, as indicator of safety performance evaluation 
in this paper, as shown in Table 1.
