“…Environmentally directed technological change in a simple one-good-twosector growth model with environmental constraints is discussed in [20]. According to their analysis substitutability of clean and dirty inputs is very important to avoid growth losses.…”

This paper brings together the debate on economic impacts of renewable energy (RE) deployment and the discussion on modelling endogenous technological change on the global markets for the different renewable power generation technologies. Economic impacts of RE deployment are still mostly discussed on national level, where different effects have been identified. Recent research for Germany shows positive effects on the macro level and different distributional impacts. High investment in solar photovoltaics (PV) from 2010 to 2012 and induced increases in the RE surcharge are the main drivers. At the same time, cost reductions for wind and solar PV take place on global markets, with global learning curves explaining the cost reductions very well. This calls for better including the international dimension into the modelling. The complex feedback loops between global cost curves and national policies, which react to global learning with some time lags, are not yet integrated into complex economic models. These models have to capture different RE technologies, different industries, either delivering the RE technologies or strongly depending on electricity prices, which are influenced by national support policies and macroeconomic development. As a first step to better understand the role of international markets, assumptions on RE exports based on global scenarios can be used. Results show the importance of global markets at least for the German RE industries. If the international dimension is taken into account, mainly positive economic impacts of further RE deployment can be observed.

“…There is a far-reaching consensus among economists that carbon pricing is a highly desirable form of climate policy (Acemoglu et al 2012;Tirole 2012;Stiglitz 2016). The World Bank (2015) and the IMF (Parry, Veung, and Heine 2015) also recommend it as an efficient way of combining environmental and economic objectives.…”

“…These two figures show the achievements in the pursuit of sustainable development. One possible explanation for these phenomena is the directed technological change and innovation toward clean inputs with relevant policy interventions (Acemoglu, Aghion, Bursztyn, & Hemous, 2012). Figure 1.3, in contrast, shows a challenge for sustainable development.…”

“…Although there are many other fascinating aspects in the process of sustainable development, we pay a special attention to energy efficiency and the technologies involved, not only because of a concern of data availability as well as financial and time constraints, but also because energy is one of the most important inputs of economic activities. Furthermore, technological change and policy instruments can play central roles in the improvement of energy efficiency (Acemoglu et al, 2012;Allcott & Mullainathan, 2010;Jaffe, Newell, & Stavins, 2002). As a result, the dynamics of energy efficiency can reflect the evolution of technology in relevant fields and provide useful recipes for the design of development policies and strategies.…”

“…Moreover, according to growth theory, continuous improvements in technology, especially in those that increase input efficiency (e.g., energy) are likely to help the global economy overcome limitations to growth in the face of scarce and unrenewable resources (Grossman & Helpman, 1994). More recently, Acemoglu et al (2012) extend the notion of directed technological change (Acemoglu, 2002) into a growth model containing environmental constraints. They theoretically prove that sustainable development, a process in which directed technological change towards clean inputs can play a crucial role, can be achieved if inputs are sufficiently substitutable.…”

Finally and most importantly, I would like to express my sincere gratitude to my parents, who always believe in me and have endured my absence from family for so many years. Thank you so much for your love, support and giving me the freedom to chase my dreams. 11 SummaryAs an influential development paradigm, sustainable development has gained broad support from various governments and organizations at regional, national and global levels. It is a process involving many important dimensions and its study requires efforts from researchers from all the disciplines of natural and social sciences. In this thesis, we focus on energy efficiency, a key element in the pursuit of sustainable development. The dynamics of energy efficiency is an evolutionary process that involves industries, technologies and institutions. Therefore, it requires a wide range of policies, aimed at both macro and micro levels. It is of primary importance to have a careful economic study of all the detailed processes that are involved in the policy-relevant areas. Numerous programs, funds, facilities related to energy efficiency have been implemented so far and are still ongoing. In the study of energy efficiency, many policy-relevant areas that require numerous research and financial inputs and careful empirical analysis are involved. Due to data availability and the feasibility of this study to be effectively conducted, as an early step, we narrow down our research at micro and macro levels to the following aspects: energy consumption and energy efficiency at sectoral and country levels, aggregate vehicle energy efficiency (regional level) and the technologies related to energy efficiency in the fields of power station, ICT in buildings and vehicles. We hope that our results can shed light on the relevant policies and studies in the future.Using large datasets, this dissertation provides a comprehensive narrative of how energy efficiency and the technologies related to energy efficiency evolve over time. We develop a new analytical framework and several measures for crucial factors affecting energy consumption and energy efficiency in trade at sectoral and country levels. Based on big data of individual vehicles and their owners, we design an empirical statistical approach to estimate regional aggregate vehicle energy efficiency that is formed by the technological characteristics and collective behaviors of micro-agents (e.g., purchase and usage of vehicles and migration), and describe the life cycle and restructuring of the vehicle population. Also, we identify the technological trajectories of technologies related to energy efficiency, and develop some measures for whether a country can be classified as an incumbent country or a latecomer country, and for how much a country contributes to technological development. The approaches used in this dissertation that build aggregate or macro measures on the basis of detailed and micro large datasets are of great value for the study of economic, industrial and scientific evolution. The 12 optimal ...
