Sammanfattning

The empirical evidence concerning the job-creation impact of wind power technology through knowledge spillovers is yet poor. Our objective is to contribute to the literature and bridge this gap. Specifically, our analysis explores to what extent investments in innovation activities of one firm affect the neighbouring firms’ generation of knowledge spillovers in the same sector (intra-industry) or to different sectors (inter-industry) and how this complex knowledge diffusion process impacts the employment dynamics. The econometric analysis relies on a sector-based panel dataset for the USA, Europe, and Japan between 2002 and 2017. The empirical findings suggest that there were negative employment spillovers from the same technology sector (Marshallian externalities) while the spillovers from more diversified activity (Jacobian externalities) have a positive impact on job-creation. The findings have relevant policy implications for governments who are developing an industrial strategy for wind power technology.

Sammanfattning

In this paper, the questions of how support policies affect invention and diffusion of solar PV technology and whether the effect is heterogeneous and counteracting are investigated in order to help policy makers produce a better policy mix. The policies (and policy proxies) investigated are Feed-in-tariffs (FITs), Public R&D stock and flow, Environmental tax, and Environmental Policy Stringency Index. The policies are within the control of national government and no EU level policies are investigated. Evaluating policies on several dimensions is highly important since there is a risk that policies can promote one aspect of technological progress such as invention but derail diffusion. A Schumpeterian technological development approach is utilised on a panel dataset covering 23 European countries between 2000 and 2019. Two econometric approaches are employed, a negative binomial regression model is used to assess inventions and a panel data fixed effect regression is used for the diffusion model. The empirical findings suggest that no counteracting policy effects were present.

Less from more: China built wind power, but gained little electricity.

Sammanfattning

This chapter investigates Chinese wind power development and concludes that innovation cannot be pushed by the efforts of many, and that when the state clarifies directions and objectives, these can be achieved but with severe and unexpected side effects. Two topics are explored: wind curtailment and low technological development, both examples of unproductive entrepreneurship induced by government policies. The goal of wind power capacity expansion leads to construction (i.e., generation capacity) but little electricity. Examples of failures include low grid connectivity with, some years averaging 15% of generation capacity broken or unconnected to the grid. A key lesson for Europe is that forced innovation often amounts to little and that the old saying holds up: “no plan survives contact with reality.”
