Knowledge-based innovation

• There are probably three ways to measure knowledge-based innovation system in terms of networked communication

- Journal articles: Traditional knowledge indicator; Scientometric

- Patent registration: Innovation indicator; Technometric

- Website links: Digital (proxy) indicator; Webometric

Knowledge-based systemness

• A surprising growth of SCI publications with a Korean address

- Korea increases its percentage world share of publications with approximately 0.20 percent point each year (r 2> 0.99). In terms of the number of SCI papers, Korea occupied the 14th position in the year 2005

- Korea obtained even the 6th position during the first eight months of the year 2004 in the field of nanotechnology

Increasing Korean SCI journals

Korea’s portfolio becomes strong?

• The answer is both yes and no

• Why YES?

- Research evaluation and scholarly practice become internationalized and national R&D budget is growing

- WCU (World Class University) project

- YES part is not the focus of this presentation

Critical points and frustrating aspects

• Only three scientists working in Korean institutions were included in the 2008 list of ISI’s Highly Cited Researchers

• Korean SCI journals are being neglected by domestic/international scientists as a reference journal

- These journals function more like publication places, neither research channels nor information sources

Position of Korean SCI journals?

Networked innovation system

• A knowledge-based innovation can no longer be attributed to single nodes in a society

• New technologies enable individual and institutional actors to collaborate in new modes

• Is Korea national R&D system strong in terms of networkedness?

Gov’t policy and TH

• The networked knowledge infrastructure can be measured in terms of a Triple-Helix of University-Industry-Government relations; L. Leydesdorff

• Does Korea governmental policy facilitate the development of cooperation among individual/institutional actors comprising of national research system?

Government Characteristics of R&D programs related to the TH indicators

Park, Jung-Hee(1970-1979)

Government’s strong push to run governmental institutes and joint research between universities and public organizations

Chun, Doo-Hwan

(1980-1987)

Merger and acquisition among government-sponsored research institutes; e.g., the integration of the KAIS (Korea Advanced Institute of Science) university and the KIST (Korea Institute of Science and Technology) into the KAIST (Korea Advanced Institute of Science and Technology)

Roh, Tae-Woo(1988-1992)

The gradual opening of research organizations in both private and public sectors; e.g., KIST became independent from KAIST in 1989

Kim, Young-Sam

(1993-1997)

Dominance of governmental agencies from early 1990 to 1997 when Korea started to be subject to International Monetary Fund (IMF) conditions

Kim, Dae-Jung(1998-2002)

BK21 project started in 1999 to increase the research capacity of universities through large central government subsidies, thus decreasing UIG joint research

Roh, Moo-Hyun(2003-2007)

Continual promotion of the BK21 and internationalization of R&D, particularly in the academic sector

The Mutual Information in Two Dimensions:

Tij ≥ 0The Mutual Information in Three Dimensions:

TUIG = HU + HI + HG – HUI – HIG – HUG + HUIG

TUIG is potentially negativeA negative entropy can be a consequence of the mutual relations at the network level. The configuration then reduces the uncertainty.

2-year moving average

Have changes in government research policies affected longitudinal changes?

First, there is the reduction of uncertainty among academic, public, and industrial research actors in the Korean publication system from 1970 to 1990.

Second, the mutual information among the three TH agencies (Tuig) is relatively stable during the 1990s but begins to decrease over the last ten years. The trend line shows that the TH dynamics of UIG relations have varied considerably; this variation generally accords with changes in Korean government research policies.

Inter-regional collaboration

• Three kinds of data set among 16 Korean regions were constructed: Total number of publications, citations, cited articles

• Network measures- Centrality: sum of connections- Density: cohesive properties- Fragmentation: to identify the key actor

whose replacement is extremely urgent if the actor is excluded from the network

Seoul’s (normalized) centralities and overall network centralization

Summary of centrality analysis

• In the last 10 years, the centrality of Seoul in the co-authorship network was clearly decreasing. peaked in 1990 at 34.38 and then decreased to a plateau

• Attributed to the emergence of Dae-jeon and Kyeong-gi

• The re-structuring of the two regions was obviously a result of government interventions

Density values 1974-2006 for all categories, SCI-only, SSCI-only

Summary of density analysis

• The co-authorship networks of Korean provincials became more cohesive over the last three decades (0.004 in 1974 to 48.779 in 2006), revealing the rapidly increasing collaboration among geographically dispersed researchers and institutions.

• Need to look at longitudinal trends of ‘clustering coefficient’ besides densities

Fragmentation value when one key player, Seoul, is removed

Summary of fragmentation analysis

• Seoul was identified as the key player over the decades but NOT selected as the most important key player from 1992 to 1994

• Dae-jeon was identified as the key player in 1992 and 1993 and Busan in 1994 in the co-authorship network

• In the cited article network, Dae-jeon was chosen as the most powerful key player in 1992 and 1993 and Kwang-ju in 1994.

Web indicator for knowledge and information networks

• Links between sites might not provide for actual knowledge/information flow

• But one university receives more links from another, this can be because it is more productivein terms of scholarly performance (e.g., journal article publications, class materials, pre-prints etc.)

• Or two universities are more collaborative than ..

• Indicator for quantity, not quality??

• Hyperlinks tend to reveal both existing and emerging socio-communicational network

Universities in Eurasia (at least 100 hyperlinks)

Universities in Asia (at least 20 hyperlinks)

Universities in Asia (at least 50 hyperlinks)

Summary of ASEM links

• Clear geographic trends are visible, with most universities connecting mainly to other universities from the same country

• A closed-network among China and Singaporean universities: Collaboration

• Academic digital divide

- European universities (e.g., UK) have more incoming links than Asian ones

Discussion issuesDiscussion issues

• Role of hyperlinks as an indicator of what?

- Innovation activity- Scientific activity- Communicational

activity- Proxy VS Actual- Comparable to citation

Configurations may constrain the further TH developments at national system level by generating more uncertainty than can be managed by three TH actors- L. Leydesdorff
