Introduction: medical biotechnology
● Knowledge intensive & dynamic– combining “medical” with “technology” in surgical devices,
imaging, diagnostics, monitoring, implants, etc.
● Extensive collaboration between industry, universities, public research institutions, hospitals – and globally
● Socially relevant, especially in reducing medical costs and improving the quality of life of an aging population
● US$325 billion in revenue (2014)
4
Research goals
● Bring together different theoretical perspectives on innovation performance– Regional: specialization/diversity, agglomeration, regional
scientific base, regional university-industry-government collaboration (Triple Helix), etc.
– Global Network: collaboration between individuals/institutions & directed knowledge flows (e.g. branch → headquarters, foreign university → local company)
● To eventually explore sectoral differences and similarities
5
Methodological approach
● Mixed approach: economic geography + economics of knowledge + social network analysis + scientometrics + GIS
● Scientometrics (patents and scientific publications)– Used for the extraction of knowledge, social networks and regional
indicators– Sources: PATSTAT (EPO), Scopus (Elsevier) & OECD regional patent
statistics
● Estimation of a regression model● Validation & interpretation with case studies and expert interviews
(planned)
6
Indicators: defining the region
● OECD's Territorial Level 3 (TL3)● Offers link to the OECD regional patent database
– OECD countries, BRICS, Romania, Taiwan & Singapore
● Scale issues: Shandong vs. Gyeongsangbuk-do● Region's threshold for inclusion:
– regional sectoral patent share > global sectoral patent share– size: min. 5 patent, 10 papers and 5 citation*
● In this study n = 136
7
Indicators: defining the sector
● PATENTS: 977,187 patent familiesPatent classifications based on a keyword analysis of ANZSIC classes:– 2411: Photographic, optical and ophthalmic equipment– 2412: Medical and surgical equipment manufacturing
from an Australian Department of Industry study (2014)
● ACADEMIC PAPERS: 75,599 publicationsScopus subject areas of “Engineering” AND “Medicine” (and excluding social sciences, economics, etc.)
8
Indicators: dependent variable
● INNOVATION PERFORMANCEof the region(1) average patent family size per researcher(2) average patent citations per researcher
9
Indicators: regional
● REGIONAL SPECIALIZATION“Location indicator”: relative concentration / global share (McCann 2014)
● REGIONAL AGGLOMERATIONtotal number of patents with inventors from the region
● REGIONAL SCIENTIFIC BASEtotal number of citations received by academic papers from the region in the field
● REGIONAL TRIPLE HELIX SHAREpercentage of patents with assignees from different institution types (university, industry, government)– Institution type based on EEE-PPAT dataset from KU Leuven
10
Indicators: networks
● COLLABORATION NETWORKS (“CLUBS”) as:– undirected networks based on co-authorship– between inventors, assignees (institutions), scientists– weighted and unweighted
● TRANSFER NETWORKS (“TEAMS”) as:– directed networks based on co-authorship or inventor-assignee relationship– from university/government → industry (Triple Helix)
or branch → headquarters (Multinational Corporation)– weighted and unweighted– inbound and outbound
12
Model setup (working draft)
● Dependent variables: patent family size + patent citations● Independent/explanatory variables:
– Regional specialization– Inventor “teams” network– Researchers (regional sectoral agglomeration)– Scientific citatations– Triple Helix collaboration (patents)– Scientific “community” network

Conclusions (tentative)
● Benefits of Marshallian agglomeration (technological diversity)
● Benefits of local scale● Benefits of inventor networks (international
collaboration and branch → headquarter relations)● “Insignificance” of basic research?● “Insignificance” of industry-university co-patenting?
20
Further applications
● “Big” data set usable for benchmarking, activity and network mapping
● Methodology applicable to all patent-intensive technologies, globally
● Interested in case studies that are backed up by interviews to validate and understand “why”
