Circular economy initiative in China
1998-2002: academic studies
2002-2005: become one of national
sustainable strategies and policies
2006-now: circular economy initiative in the
11th five year plan of economic-social
development
Three issues on CE
Why (Scenario)—China needs to decouple
economic growth from environmental impact,
but in the sense of relative decoupling
What (Model)—CE is the kind of multicycled economy towards more services with
less throughputs.
How (Strategy)—How for China to make CE
into practice.

Three scenarios of China development
Scenario 1(traditional growth): Under the present
mode,the impact of China will be at least 4 times of
the current level;
Scenario 2(absolutely decoupling): To keep the
current impact level, we should at least raise 4 times
of eco-efficiency.
Scenario 3(relatively improving): In the level of
relatively decoupling, we should raise 2-3 times of
eco-efficiency;
1. 1 Scenario#1: Economic Growth with more impacts
I=Impact: resource
consumption and pollution
impact of development
P=Population:How many
people will we have ?
A=Affluence:What’s the
consumption level?
T=Technology and
Management: How fast and
big do we consume the
resource and environment ?
Population: How many people China will
have in 2020
China has 1.3 billion people in 2000
Increasing 10 million persons per year
1.4-1.5 billion till 2020 in China (1.1 times of the
year 2000)
Demand of 10 million persons for urbanization per
year
60% urbanization rate till 2020 in China
Affluence: In terms of GDP per capita
Beginning of Reforming and Opening: $250
per person
1981-1990: $500 per person
1991-2000: $800 per person
2001-2020: $3000 per person (about 4 times
of the year 2000)
How big is environment impact in 2020 ?

To call for an alternative development model
traditional approach (high economic performance
and high environmental impacts)
The resource and environment in China are not available to
provide a growing population with higher standards in a
traditional lifestyle of consumption.
alternative approach (high economic performance
and low environmental impacts )
The challenge for China is to create an alternative one to
traditional development modes which would meet the
needs for development while maintaining and even
improving the health of ecosystem.
1.2 Scenario #2: Absolute Decoupling of
economic growth from impacts
Wellbeing
Ecological Economy
Resource throughput
Traditional development
Alternative development
Different requirements for the developed
economy and developing economy
The target for sustainable development is to reduce
the global material flow by 50% in the future fifty
years, It’s known to all that reduction of materials
into industrial countries (20% of the materials that
human possess), we can organize in this
way:increase the material consumption of southern
countries temporarily and then reduce it in the
material flow reduction plan. Maybe this is a
reasonable hypothesis of developing policy.

2.What:Towards a multi cycled economy
resource
Economic performance on the base of ecological economics
EP= Service/Throughput
= Service/Stock×Stock/Throughput
Here are three guiding principles
Maximum of service (well-being);
Minimum of resource (throughput);
Sufficiency of stock (accumulation).
To two efficiency of development
To raise productivity efficiency ( Stock/Throughput )
To raise service efficiency ( Service/Stock)
To increase resource productivity
One of the key issue of CE is for China to raise resource
productivity.
That is to decrease the resource consumption and pollution
impacts while to increase the economic output

2.3 Explanation#3: scales of circular economy
FACTORY
ECO-INDUSTRIAL PARK
REGIONAL ECO-INDUSTRIAL NETWORK
(1)Inside level of enterprises
At the individual firm level, managers are to seek
much higher efficiency through the 3Rs Principles,
reduce consumption of resources and emission of
pollutants and waste, reuse resources, and recycle byproducts.
In this regard, we want to mention that sustainable
product design or DFE (Design for environment) is
important in the current Chinese CE concept.
(2)Inter level of enterprises
The second level is to optimizing resource
efficiency within industrial parks and clustered
or chained industries, which can be larger than
the sum of improvements made by
unconnected individual actors.
But this level is simply not equal to the reuse
of by-products within the network of firms.
(3)Regional level: integration of
production and consumption
The third level is to integrate different production,
consumption and its support systems in a region so the
resources circulate among industries and urban systems.
This level requires development of municipal or
regional by-product collection, storage, processing, and
distribution systems.
One example is such application is resource-based
planning for city and regional development.

Bottom-up self-organizing model (BSM)
Emerges from decisions by private actors motivated
to exchange resources to meet goals such as cost
reduction, revenue enhancement, resource access.
The individual initiative to begin resource exchange
faces a market test and if the exchanges are
successful, more MAY follow.
In the early stages there is not consciousness by
participants of inclusion in an “industrial ecosystem,”
but this can develop over time.
Evolved Kalundborg EIP in Denmark
Top-down planned model (TPM)
Includes a conscious effort to identify companies
from different industries and locate them together
so they can share resources across and among
them.
Conceptually, it is an attempt to design and direct
a closed-loop system in a circumscribed
geographic unit.
Involves key stakeholders and the participation of
at least one governmental or quasi-governmental
agency with powers to encourage development.

3.3 Strategy#3: From general principles to context-based
theory for developing economy
To develop a leapfrog theory on the base of
ecological economics
To raise the awareness and knowledge of senior
levels of policy-makers
To develop a system policy for circular economy
How long could Ecological Economics
replace New Classic Economics?

Ecological economics: think about
the next 20 years (2008-2028)
The past 20 years: to establish guiding principles
based the high income countries (version 1.0)
The next 20 years: to improve and develop theory
and policy based on the developing countries’
practice (version 2.0)
Let China become one of the world labs for
Ecological Economics…
