In 2004,  the science and technology achievements administrative office of the Ministry  of Science and Technology of the People’s Republic of China released  the research achievements of Extenics --Extension Theory and its Application on  the website of National Achievements of Science and Technology:

The  topic of the project was selected by the first completed person  that finished in 1976.? He then published his first paper in 1983, which  proclaimed the foundation of the new subject Extenics.

Since  1988, the National Natural Science Foundation of China has supported this  research with 6 projects as follows:
                           The  Rules Research of Dealing with Contradictory Problems in Decision-making System（7870014）,
The  Theories and Methods of Transforming Bridge（7920079）,
The  Generate Methods and Coordination Problems of Key Strategy（79570020）,
The  Research of Extension Marketing Methods（79870107）,
The  Research of Theories and Methods of Extension Planning（70140003）,
The  Basic Theories and Basic Methods Research of The Extension Strategy Generate  System（70271060）,
The  Guangdong Provincial Natural Science Foundation also supported the  research with a project named The Conjugate Analysis and Extension Resource  Research for Enterprise Resource（010049）.

As the  integration of more than 20 years’ research achievements, this project engages  in studies as follows:
Using formal language to describe matters, affairs and relations,
Building formal model,
Research rules and logic of the resolution of contradictory problems,
Build a set of operable methods and provide basic theory and method for  computer to solve contradictory problems in different fields.

Contradictory  problems are the research object of this project. It studies rules and methods  to deal with the problems. The project has built the Extension Analysis Theory on  base-element, the quantitative tool—extension set and dependent function, which  support the conjugate analysis theories of matter and the expression of things’  quantitative change and qualitative change, extension logic--the combination of  formal logic and dialectical logic. The basic-element theory, the extension set  theory and the extension logic are the three pillars of Extension Theory. Based  on this theory, we found out operable extension methods, on which we can form  extension engineering methods to solve contradictory problems of different  fields, based on the professional knowledge of each field.

The creativity  of this project lied in three aspects. Firstly, it builds the formal models of  Extenics that can be used to transfer and infer and generate the strategy to  solve problems, which is different from the way of former scholars using  natural language to study contradictory problems. Secondly, it extends the  classic set and the fuzzy set to build the extension set and  dependent functions, which describe the quantitative and  qualitative changes quantitatively. Last but not least, it builds the Extension  Logic to deal with contradictory problems. This project is an original and  innovative research, leading and guiding the same kind researches at home and  aboard.

At present, many scholars from different fields  have applied the research results of this project to their own professional  areas to solve related problems and gain a lot of achievements. Scholars from  overseas also come to learn the achievements of this project and then introduce  it to their own countries. Extenics has already developed from theoretical  research to practical applications with wide prospects.
