Contribution of regional accessibility to economic growth • What accessibility to measure? • BAK accessibility model • Results • Contribution of regional accessibility to economic growth • Theoretical framework • Empirical results: Research Program „Policy and Regional Growth“ • Summary of results
Definition of accessibility Kay Axhausen (ETHZ): Accessibility can be understood as the number of opportunities available for social and economic life that can be reached within a travel time appropriate to the relevant purpose. ESPON (EU Study Programme on European Spatial Planning): Accessibility ist the main „product“ of a transport system. It determines the locational advantage of an area (i.e. a region, a city or a corridor) relative to all areas (including itself).
The modelWhat accessibility to measure? 5 questions have to be answered: 1. Who shall have access? Representatives of international companies and institutions 2. Access to what? Markets for inputs & goods (GDP as activity parameter, outbound accessibility) 3. Which measure for Travel time (fastest connection) spatial impedance? 4. Which traffic modes? Rail, road and air 5. What spatial scale? Global & continental
The modelList of destinations • Global destinations:120 international airports representing the world economy outside Europe • Continental destinations:291 regional centers representing European economy www.bakbasel.com
The modelThe accessibility function AU = S(WZ* e -b*cU Z) • A = Accessibility • U = Origin • W = Activity (GDP) • Z = Destination • c = Travel time • b = Parameter
Network dataCalculation of shortest intermodal travel time for every connection • Global connections: 280 (Origins) x 120 (Destinations)Central station origin è Central station destination outside EuropeFastest connection including:- Access time to departure airport (average of public transport and car access)- Transfer time (change of traffic mode)- Check-in time (destination- and airportspecific)- Flight time including connecting time- time from arrival airport to central station destination Continental connections:280 (Origins) x 291 (Destinations)Central station origin è Central station destinationFastest connection from modes:- Road- Railway- Flight (travel time including access and transfer time departure airport, check-in time, flight time, transfer time at arrival airport and access time from arrival airport to central station destination)

Contribution of regional accessibility to economic growth • Theoretical framework Approaches to model (regional) economic growth The dimension of „space“ • Empirical results: Research Program „Policy and Regional Growth“ www.bakbasel.com
How relevant is policy for regional growth? • Policy question: What are the drivers of regional growth? What are the measures decision makers can choose to foster economic growth? • BAK research project: Understanding the relation between location factors and Policy and Regional Growth regional growth using empirical and econometric tools • BAK Analytical Approach: • Benchmarking: Comparing economic performance and location factors • Analysis: Understanding the relationship between performance and location factors • Policy: Advice on policy measures and possible trade-offs
DatabaseInternational Benchmarking Database Economic Performance (1980-2005) Indicators: GDP Gross value added Employment Hours worked Productivity (hourly productivity and output per employee) Measures: Gross and real Level and growth (time series 1980 to 2005) In national currency and in common currency Total, per capita Industries: 60 different industries (following NACE 2-digit level)
Database International Benchmarking Database Location Factors Innovation: Expenditure on R&D* (1980-2003) University quality (Shanghai Index) (2003-2005) Number of higher education degrees* (tertiary degrees) (1990-2005) Education level of labour force* (secondary / tertiary) (1980-2003) Patents* (1990-2005) Bibliometric indicators* (1990-2005) Company start-ups* (1993-2003) Taxation: Taxation of highly qualified employees (1980-2005) Taxation of companies (1980-2005) Regulation: Regulation of product markets (1980-2003) Regulation of labour markets (1980-2003) * Indicators by industries, directly or through subjects/technology fields. Some parts of database still in development.
Database International Benchmarking Database Location Factors Accessibility: Global accessibility (1980-2004) Continental accessibility (1980-2004) Labour costs: Wages costs (1980-2004) Unit labour costs (1980-2004) Population: According to gender and different age cohorts (1980-2005) Agglomeration:Agglomeration size Proximity to an agglomeration
Why does a region grow?Econometric analysis • Theory and observation (questionnaires) can tell which location factors are important … • … but they do hardly tell the size of the impact on regional growth • Econometric analysis based on the benchmarking database • Basic equation: • Growthit = α0 + α1*Global Effectt + α2*Structural Effectit + β1*L1it-1 + β2*L2it-1 + … + εit • Panel data estimation (random effects, fixed effects) with • i = 142 regions • t = 15 years (1990 – 2004) • several location factors (L)

Summary of results • Research program on impact of location factors on economic growth • Signs of location factors largely as expected from theory & significant • Available location factors can only explain a part of the regional variation • Impact of accessibility • Accessibility matters • A better global accessibility increases efficiency and competitiveness and enhances productivity growth • A better accessibility is a double-edged sword: On the one hand, it enhances business activities and boosts the attractiveness of a region. On the other hand, it allows high value activities to be delivered from a central region • Further research is necessary!
Research agenda • Further research directions • Regional coverage • More specific on sources of growth (productivity, hours worked, employment ratio, population) • Advanced Methods (system estimation) • Add more location factors, especially varying between regions(regulation; fragmentation and decentralization; innovation; …) • Industry specific estimations • Further research directions (accessibility) • Sub samples of regions with similar characteristics • Industry specific estimations • Research on the intraregional accessibility • Mix of macro-economic and micro-economic methods
