A New Humankind Economy Age : Knowledge Economy Age
Attended by the footstep of 21
century, Humankind economy age, which is like a strapping, full of energy and
huge Titan, is coming towards us. It tells the world that a new era based on knowledge
is coming. It is both a first-born life and like a “society Titan”,
which is strong enough and full of energy. The future world will spread along
its foot.
Knowledge economy
means that the dev-elopment of economy chiefly lies on the possession and collocation
of the knowledge source. Kno-wledge is the first productive forces. Technology
has become the decisive factor of the economic development, which is based on
knowledge. It is a new type of knowledge, which is deferent from the one that
is chiefly based on traditional industry and rare natural resources. Taking high
tech industry as its first industry pillar, it is a sustainable developing
economy, which is chiefly based on intelligent resources. It is the new type of
knowledge, which is depending on the production, circulation, distribution and
application of the knowledge and information. Knowledge is the soul of the
knowledge economy. Only by transforming the information to knowledge can we
improve the development of knowledge.
The nature of
knowledge economy age has decided the 10 features of this age: the global
economy, pluralistic development, aggregate ability, dense knowledge, knowledgeable
decision-making, intelligent operation, bodiless investment, shareable
resources, high speed run and sustainable development. Knowledge economy is a material
economic phase. When economic base is changed or reformed, the society life,
political life and mental life will follow it. Thus the society will take on a
new look.
However, if not
solved in right way, the factual problem we have to face in modern society and
the other problems accompanying will prevent people from proceeding to the
knowledge economy ages. At the same time, the problems, such as pollution, the
pollution of environment, greenhouse effect, abnormal climate, vegetation being
destroyed, earth changing into desert, population flood, information explosion,
and sustainable development, has become focal and hot. Of course, the
technological development in knowledge economy age must provide a technical powerful
support for solving these problems. Accordingly the Digital Earth comes into
being.
Digital Earth is an
information earth and an information model of earth. According to the geographical
coordinate, it packs up all the information on the earth to a global
information model. It thus allows everybody in the world to know about the
earth macroscopically and microcos-mically in a rapid, integrated and visual
way and give these data a full function. It is widely used in many fields, such
as agriculture, earth lay out, education, crisis resolving, sustainable
development and preventing and decreasing disasters. So, it turns the idea——“information is just in hand”——into reality and finally improved
the development of society and economy.
In the society, which
takes knowledge as its characteristics, information is primary economic
resource and the information technology is the primary productive forces of
resources. Digital information is the physical form of knowledge economy. The
digital earth, which featured by dealing with the all the relevant spatial data
and text data about the space, will be the core of the future information
resources. It provides room and tools for the productivity, exchange and
application of knowledge. With the developing of science and technology, we can
require, save, deal with, and display many kinds of environmental and cultural
phenomena information about out planet. The ability of acquiring remote sensing
data is improved continuously. The data resources from the earth observation
system, such as GPS, GIS, and ground station，is abundant. Digital earth spares
effective data from the large amount of data and turns it into valuable
knowledge economically. So, digital earth will play an important role in knowledge
city economy of knowledge economy age.
2. The Intellectualized City
Economy in Knowle-dge Economy Age
The development of industry society
improves the upgrowth of city, but it bring out the population explosion, the
lack of all resource, the pollution of environment, instability of the economy develop-ment,
and other complicated problem which refer to many questions, the development of
society need to consider many kinds of questions, and we must response and make
decision to these complicated problem as soon as possible, industry society can
do nothing to these, so the development of society need to new increase point
of continual develop-ment.
After society has
developed to a civilized one, materials, energy and information are becoming
three huge resources, which are the components of the social material life.
Moreover, information is the most important exploited one in the three
resources and it is so-called the start-up resource, which will become more and
more important when the day of the information comes to now. Informative
society and information modernization is the basic signal of the knowledge and
economic society. The science technique will make great progress and economy
will develop to an advanced phase in such society. The whole society and the
living style of the human being will change great and these changes will bring
out the prosperity of the economy and the development of the society.
The knowledge economy
will make the construction of the city into a new epoch. The layout target of
the city is about 150 years or longer. A big city is connected with hundreds of
small cities and each city is made up of several super buildings. The area of
the big city is about 10,000 km2. The quantities of the super city
buildings become more and more huge.
In 2030,there are 20
city “nation” in the world, There are over 30000 thousand people in
each city, such as new York, Los Angeles in America, Shanghai in China, Djakarta
in Indonesia. These cities make up of a large scale of “city
nation” through many residential area and satellite town or Midway City.
These networks would be develop and expand, and form into new combination. They
come into Being City “continent” that live in new form in 2080s.
There are over 70000 thousand people in each city, in these rate, there grow up
into many city “world” in the end of 21 century. There 1-2 a
hundred million people in each city. In the end of 21 century, there are super
cities in the world, which have 40000 thousand people and 200 thousands km2.
So in the knowledge economy age, city economy is a huge economic system
engineering, it will change every aspects of city plan.
The rise of knowledge
economy is another important revolution in human economic field. It makes world
city plan into a new age. Global communication network will build, global
information will bring out .So Knowledge City, as the center of politics,
economy, culture, information will be focus on and huge more and more. Building
city’s information model and architecture, making study of city’s continuance
develop, Building City’s function system, it would be make stability foundation
for the future development of knowledge city economy. We can get all kinds of
information that we need in our life from information life space, on the other
hand. It can stimulate people’s requirement of information consumption,
create new economy increase point, so it reduces need of all kinds of resource,
makes environment pollution decrease, improve the benign circle of economic
development.
3. The Application of Digital
Earth in An Intelle-Ctualized City
The presentation of this concept of
Digital Earth is based on the new technologies that man has possessed or will
master in the future, "Information is just in hand", but there is a
set of complex substructures. It is a great and complex system engineering,
which needs not only a uniform frame and coordinated working environment but
much more new technologies such as computer and network communication, satellite
remote sensing technology, GPS, VR, GIS, Data Storage and Database. The
progress and further development of these technologies lay a solid foundation
for the research on an intellectualized city.
The development of
information society and the evolution of cities, based on information
superhighway, require organizing the extensive data sources, managing and
combining a vast amount of information. By use of technologies such as data
dig, knowledge extraction, man can provide virtual interface and strong
decision-making management function to sustain survival information requirement
of government departments and the public, back sustainable developmental city
information life space. It has excellent virtual simulate environment and
strong decision-making function. It will embody the importance of information
consumption for human from all aspects and promote man's need for information,
and make information industry a new economy growth point and a symbol of the
age of knowledge economy. City population and industry distribution will
undergo dramatic changes. Pollution, as well as man's need for energy, will
decrease. Research achievement of Digital Earth and key technologies will
provide strong technical support for the information space construction in an intellectualized
city consequentially.
3.1. The Information Model and
System Structure of An Intellectualized City.
(1)The construction of information
model.
Information in an intellectualized
city will cover all aspects of city life, which includes municipal
administration, transportation, electricity power, environment issue,
education, entertainment, etc, each with individual complexity and
corresponding characteristics. If combined, their relationship will also be
very complicated. So it is necessary to study such complexity, reveal their
inner relationship to provide the basis of information model construction.
Based on the research
of complexity in an intellectualized city, system of model construction tools
should be presented so that man can demonstrate individual characteristics and
relationship of complicated information in an intellectualized city.
Rationally, by use of city model construction tools system model demonstration
should be applied to information structure so that man can build a city
information model.
(2)Research on the system structure.
An intellectualized
city is constructed based on information superhighway. A good system structure
should be applied to complicated network structure so that man can construct a versatile,
expansible operational system. The system structure of an intellectualized city
will include systematic structures (such as collectivity, logic, and operation)
Manage-
ment of information, tactic system
of information transform and corresponding data coding, transform standard
system.
3.2. The Supporting Research of Sustainable
Development in An Intellectualized City.
The construction of an intellectualized
city will provide an excellent tool for and solution to sustainable development
of society. Urban population distribution, resources requirement, environment
pollution, industry structure of society will change fundamentally. Research from
the perspective of supporting sustainable development will direct its
application theoretically in an intellectualized city.
The supporting
research of sustainable develo-pment in an intellectualized city will study how
to support city model construction and operational system in sustainable
development. It will also study the function of the industry of urban society
in an intellectualized city.
3.3. General Supporting
Technology Research in An Intellectualized City.
(1)The organization
and management of city data source and data exchange.
Intellectualized
city's data come from different sectors. Information sharing needs to convert
present different database information sources to consistent data sources
according to uniform data standard system. Urban data exchange technology will
be built based on this technology.
(2)The management of
decision-making model.
The decision-making
model and method that intellectualized city concerned have such characteristics
as multi-factor, algorithm complexity. Besides, there is lots of complex links
between sectors and specialties. Employing research achievements such as data
dig, knowledge extraction and component technology of Digital Earth, a
simplest, complete model and technique will be constructed by which
decision-making model management will be realized in an intellectualized city.
(3)The action
simulation of sustainable de-velopment
Before various
general or special urban plans are carried out, a simulation can be made by use
of the achievement of city information research, to decide whether or not a
plan will meet sustainable development's requirement quickly and thoroughly. In
view of the multiplicity of plans and the difficulty of simulation, it's
recommended that a special research be conducted on this. The research includes
3 dimensions or 5 dimensions all-purpose simulation study aimed at different specialties,
construction of corresponding component set and prototype system.
(4)The information security
system.
Information in an intellectualized
city will concern information coming from every walk of life, including secret
of governments, enterprises, military units, etc. Therefore the information security
system in an intellectualized city is an important aspect which includes
information encryption technology research on system structure, hardware and
software and such aspects.
3.4. Function System in An Intellectualized
City.
(1)Data management and exchange
center.
Collect various existing data
sources to realize information sharing. The
construction of data management and exchange center will provide an information
sharing platform to deal with various information in an intellectualized city.
(2)General Public
information platform.
General Public
information platform in an intellectualized city is a functional system mainly
used to offer general public services such as route navigation, real-time
weather inquiry, network shopping, network education and so on.
(3)General and professional management progra-mming information system.
The main purpose of
general and professional management programming information system is to standardize
all kinds of constructions according to sustainable development theory and
professional criteria. It includes subsystems such as urban environment plan,
urban transportation blueprint, manufactory plan, city utility layout, OA.
(4)Sustainable
developmental decision-making supporting system.
Sustainable
developmental decision-making supporting system in an intellectualized city is
a decision-making system, such as sustainable developmental tactic
decision-making system.
It can be predicted that extensive application
of the achievement of Digital Earth research in an intellectualized city will
bring about both great social and economic benefits. It's beneficial to the
general city planning, crime preventing and cracking down, safety precautions
of city, agriculture production increasing, layout and implementation of city
environment protection, emergency dealing, management and application of urban
utility, management of urban public information, manage level and quality of
education, sustainable development of city. At the same time, it will build necessary
base for completing the construction of Digital Earth thoroughly. It will
provide positive and profound influence on sustainable development of human
being.
