Abstract: To study the status of the regional innovation system from 1990---2009 in the co-citation analysis, multidimensional scaling analysis, cluster analysis and factor analysis, on the basis of drawing knowledge map of Regional Innovation Systems International, the map shows the research of the regional innovation system has three main research groups and research in the field, finally, the results were discussed and prospects.
Keywords paper: regional innovation system; knowledge map; academic group

Since the second half of the twentieth Century, the global technology development has two characteristics, one is the innovation resources globalization flow speed: two is the regional innovation activity aggregation tendency.Some distinctive and competitive advantages of regional become global economic development of the "growth pole" or "innovation pole".Region has become an important carrier of organizational innovation.The research of the regional innovation system and academic management has attracted more and more attention of all countries, has also emerged a substantial research results with high theoretical and practical value.In order to better understand the focus on the research of the regional innovation system in the academic circles at home and abroad, this paper use the knowledge graph Scientometrics in this emerging international visualization technology, the research of regional innovation system, the main point of view, representatives expressed by visual images, research on knowledge of international regional innovation system the formation, vividly demonstrated the development of the research on the regional innovation system in recent years, has laid a good foundation for related research.
The 1 data source of
In the United States Institute of scientific information (ISI) SCI (Science Citation Index), SSCI (Social Science Citation Index) and ISTP (index to scientific & Technical Proceedings) all the 1990--2009 included 3 Web database, using GENERALSEARCH TOPIC column, enter "RegionalInovationSystem" (regional innovation system is a word, 237) papers from the retrieved, extraction of cited author 2013, total cited frequency is 5322 times, the average author cited 2.64 times, extraction times cited the highest 5O authors.The total cited frequency of 1230 times, accounting for 23.2% of the total cited frequency, the average for the 24.6 time.
Knowledge map of 2 analysis of regional innovation system
Basic thought of this method is: firstly, knowledge mapping analysis by Bibexcel software for co-citation analysis of the downloaded to the author, generating the co-citation matrix, on this basis. Using SPSS software, analysis and multidimensional scaling analysis, cluster analysis, factor, and then draw out the knowledge map of regional innovation system, this image reveals the main academic groups existing in this field and focus....
2.1 co-citation analysis
For co-citation analysis using Bibexcel software (including the Co-word Analysis and co-citation analysis.).The author of the co-occurrence analysis is also known as the author co-citation analysis (AuthorCo - citationAnalysis). It is one of the most basic method of knowledge map drawing.The author cites, select the citations ranked the top 50 of author co-citation analysis and generate the co-citation matrix, then the SPSS software to get the correlation coefficient matrix.When the n bit is one of the authors and references, can think of this n authors and cited authors are the monographic study of peers, and co-citation frequency is high, indicating more close professional relationship between them, in the knowledge of the location is also close to the.The cited frequency in 5O authors see table 1.

2.2 multidimensional scaling analysis and clustering analysis of
by using the software of SPSS was analyzed by multidimensional scaling.Multidimensional scaling analysis through low dimensional space (usually two-dimensional space) to show relationships between objects, and the use of plane distance to reflect the degree of similarity between objects.The author co-citation map of knowledge, the author (each) shows the location of the similarity between the authors, has a high degree of similarity of the author together, forming the discipline of "intangible" academic groups, and the more the more the author to have contact with him in the middle of the author in the subject position. The more the core.Therefore, through the analysis of multidimensional scaling, a hot academic and research group is easy to judge.
The statistics on the according to certain requirements and rules, method of classifying things, called cluster analysis.The cluster is a group of heterogeneous groups separated into clusters or subgroup isomorphic nature high. Clustering and without clearly defined categories to classify.Non clustering operation, does not need to be defined in advance how to classification, data is to rely on the similarity to cluster together in itself, while the qualitative clustering significance is to rely on the post description to know.System of successive clustering analysis method "use" the study, in the clustering of the author, firstly, each author as an independent category. Then two kinds of recent merger.And then to calculate the distance between classes.Finally, the distance of two kinds of recent merger, each step of reducing a class, until all the authors classified as a class.
We will multidimensional scaling analysis and clustering analysis results together.And read the relevant literature, that the regional innovation system research, development trend and existing "intangible" academic group.
In the field of research on regional innovation system 17 years of citations in 5O writer is author co-citation analysis, then we analysis and multidimensional scaling analysis and clustering. Draw the figure of scientific knowledge mapping major academic group international entrepreneurial university research field and its representative figure 1.

The cluster analysis was performed by relevant literature on the first several authors 50 authors cited the most, we know that the clustering, three mainstream academic research in the field of regional innovation system of international and related academic groups and research hotspot.
In the three academic groups, academic group of 1 main research on regional innovation system theory origin and basic principle, representative of this group include Freeman (Freeman), Landwehr (Lund.vail), Potter (Porter), Nelson (Nelson), Ai De Quist (Edquist), Patel Pavitt (PatelandPavitt), Cook (Cooke), Bratsk (Braezyk), Carlsson (Carlsson), Florida (Floirda) et al.Academic group of 2 mainly from the internal structure of the regional innovation system is studied, the representatives of groups, including Krugman (Kl31gman), becattini (Becattini), Ma Squee I (Maskel1), Achim (Asheim), Camagni (Cam - Agni), Remy GIO (Remigio) et al.Academic group is mainly from 3 perspective of effectiveness of regional innovation system research, including knowledge spillovers, knowledge diffusion, knowledge transfer and other fields, the representatives of groups, including Mansfield (Mansfield), green (Griliches), the Jaffe (Jaffe), Akos (Acs), he (Audretsch) et al.In addition, from the knowledge map can be seen visually, academic groups 1, 2 and 3 more closely linked. This shows that the regional innovation system research are not isolated, there is a certain degree of cross each other.
The 2.3 factor analysis of
The principal component analysis method is used in this paper to "", author co-citation matrix is analyzed, and the oblique conversion to simplify the structure of factors.According to the author co-citation results of factor analysis, the accumulated variance contribution rate of the first three principal components 81.839, see table 2.

Research by the author co-citation factor analysis shows the regional innovation system. 1 academic fields that belong to "the theory origin of regional innovation system and the basic principle" as the representative of the people, in the most, in the research of the regional innovation system in the
Active academic field; 2 is not the most active areas of concern, but to "study" the internal structure of the regional innovation system; academic field 3 "regional innovation system performance." it reflects the new characteristics of the regional innovation system research and development.
The above on the regional innovation system research division.Can be found, the research on regional innovation system has gradually from the understanding of the basic connotation of theoretical sources, the initial to the internal structure, the effectiveness of such mechanism development.Of course, different scholars in different stages, different research emphases, overall.In each of these areas have been studied deeply. But due to the different angle of view research scholars and analysis for different cases. The research has become more detailed but a bit scattered, has not yet formed a theoretical system in a clear, logical framework.Therefore, must stand in the angle of system theory, make a study on field research on regional innovation system as a whole, all kinds of relationships in order to clarify the regional innovation system, promote the construction of regional innovation system, enhance the independent innovation ability.
