Identifying Lead Markets in the European Automotive Industry: An Indicator-based Approach

This paper presents an indicator-based methodology to identify lead markets in the European automotive industry. The lead market approach tries to explain why certain countries are better positioned than others for developing and launching new products. While much research stresses the role of excellence in technology and interaction among users and producers, the lead market approach focuses on the role of demand characteristics. Based on the concept of innovation design, a lead market is defined as a country where customers prefer that design which subsequently becomes the globally dominant design. We use an indicator-based approach which has been successfully employed for individual products as well as for various industries in order to identify lead markets in the European automotive industry. Employing five lead market factors, our results show that the EU is by far no homogeneous market for automobiles and national markets differ considerably in their lead market potential. The German market is found to be most promising to serve as a lead market, while other European countries with a strong automotive tradition like France, Italy, the UK, and Sweden score lower. Our findings suggest that firms from the automotive industry should exploit this diversity of market characteristics within Europe when developing and launching new products.

Upgrading of Symbolic and Synthetic Knowledge Bases: Evidence from the Chinese Automotive and Construction Industries

This paper deals with the question of how upgrading of the symbolic and synthetic knowledge bases takes place and, by doing so, we contribute to the upgrading literature by linking upgrading with the concept of the differentiated knowledge bases. We discern a number of upgrading mechanisms, and based on empirical evidence from the construction industry and the automotive industry in China, we show that the main upgrading mechanisms for symbolic knowledge include “learning-by-interacting in project teams” and “monitoring”, while upgrading of synthetic knowledge takes place via “technology transfer” and “learning-by-doing and-using”. “Mobility” and “on-the-job training and learning in Transnational Corporations” are the main upgrading mechanisms contributing to the development of both knowledge bases.     

A Comprehensive Evaluation of Policy Effectiveness for Energy Efficiency in Existing Buildings

The healthy and stable development of energy efficiencies in existing buildings cannot be separated from effective policy operation, and evaluating policy effectiveness contributes to scientifically-sound government decision-making. This paper creates an evaluation index system and a grey comprehensive evaluation model for policy effectiveness for energy efficiency in existing buildings using three dimensions: 1) the effect of the policy itself; 2) the administrative effect of the policy; and 3) policy implementation effects. It chooses the government’s subsidy policy and preferential tax policy at market cultivation stage for its empirical comparative evaluation. The evaluation indicates that the former is more effective. Finally, it puts forward policy development suggestions from the perspective of: 1) clarifying incentive object; 2) broadening incentive scope; 3) increasing incentive intensity; and 4) innovating incentive mode.
