local  government  in  the  ocean  energy  development 
evolution process of policy making. 
2  DATA USED AND 
METHODOLOGY
 
2.1  Data Used 
The  article  collects  the  ocean  energy  policy  issued 
by  11  coastal  provinces  and  cities  of  China  from 
2005  to  2015,  establishes  a  policy  database  of  242 
policies. 
Based  on  the  key  words  "ocean  energy"  and 
"marine  renewable  energy",  the  policy  text  is 
collected in the database of the "Beida Fabao- Laws 
&  Regulations  Chinese  Database", 
‘http://www.pkulaw.cn/’. Ensuring the effectiveness 
and  correctness  of  the  collection  policy,  this  paper 
selects policy text based on the following principles: 
First,  policies  promulgated  must  by  11  coastal 
provinces  and  cities  of  China,  Shandong,  Zhejiang, 
Fujian,  Guangdong,  Guangxi,  Hainan,  Jiangsu, 
Liaoning,  Hebei,  Shanghai  and  Tianjin,  not 
including national level issued by the relevant local 
policies  promulgated  and  other  provinces.  Second, 
policies  closely  related  to  ocean  energy,  including 
ocean  waves,  tidal  range,  tidal  currents,  ocean 
current,  ocean  thermal  energy  conversion  and 
salinity  gradients,  offshore  wind,  marine  biomass 
which  occupy  sea  space  but  do  not  directly  utilize 
the  properties  of  seawater,  are  not  included  in  this 
paper. Third, the policy form must be in accordance 
with  laws  and  regulations,  opinion,  plan,  notice  or 
other documents, reply are not included. 
2.2  Textual and Quantitative 
Methodology 
First, this paper adopts the content analysis method 
to code 242 ocean energy policy texts released by 11 
coastal  provinces  and  cities  of  China,  according  to 
"policy  number-specific  terms/chapters”.  Second, 
based on the classification method of Rothwell and 
Zegevld (1985), Liao (2016), it is divided into three 
types  of  policy  tools:  supply,  environment  and 
demand,  and  subdivided  into  five  sub-categories 
under each category according to the characteristics 
of  ocean  energy  policy,  the  formation  of  ocean 
energy  policy  text  content  analysis  unit  code  table. 
Third, classify and summarize the frequency of text 
content. 
3  RESULTS AND ANALYSIS 
3.1    Overall Analysis 
This  part  would  be  divided  into  a  count  of  the 
number  of  policies  and  secondly  the  form  of  the 
policy. 
3.1.1  Policy Number 
Chinese government usually follows five years as a 
planning period. This paper divides the period from 
2005 to 2015 into two equal periods, which conducts 
a  comparative  analysis  of  the  evolution 
characteristics  of  the  ocean  energy  policy  in  local 
governments. Figure 1 shows the number of policies 
released by 11 coastal provinces  and  cites  of  China 
in two periods.
 
From 2005 to 2015, local government issued 242 
ocean  energy  policies,  the  most  widely  publicized 
provinces  and  cities  are  Shandong,  Guangdong, 
Zhejiang  and  Fujian,  and  the  least  is  Hebei  and 
Tianjin.  In  the  period  of  2005 to  2010  and  2011  to 
2015,  there  were  105  and  137  policies  were  issued 
respectively. It increased 30 percent compared these 
two  periods,  and  all  provinces  and  cities  issued 
policies related to the development and utilization of 
ocean  energy.  Policy  sharply  increased  since  2011, 
was  the  cause  of  the  central  government  attaches 
great  importance  to  renewable  energy,  local 
governments  have  to  implement  the  central 
government of ocean energy policy, especially in the 
southeast  coastal  area,  ocean  energy  is  rich  in 
resources,  and  the  overall  policy  number  is  higher 
than the northern coastal areas. 
It is worth noting that the developed areas of the 
marine  economy  pay  more  attention  to  the 
development  and  utilization  of  ocean  energy,  and 
more  policies  are  issued.  The  development  and 
utilization of ocean energy technology is still in the 
embryonic  stage,  the  period  of  industrialization 
process  and  investment  return  are  longer.  A  large 
number  of  policies  will  enhance  investors' 
enthusiasm  to  investment  and  promote  the  healthy 
development of ocean energy industry.
