| Summary/Abstract |
This paper aims to synthetically investigate invention profiles and uneven growth of technological knowledge in the emerging nano-energy field, based on patents data extracted from the Derwent Innovation Index (DII) database during the time period 1991–2012. The trend analysis shows that invention in this field has experienced enormous growth and also diversification over the past 22 years. The co-occurrence network of burst technology domains reveals that technology domains constantly burst, and innovative progress in nanotechnology has tremendously contributed to energy production, storage, conversion and harvesting and so on. Nano-energy patented inventions mainly come from a combinatorial process with a very limited role of developing brand-new technological capabilities. Reusing existing technological capabilities including recombination reuse, recombination creation and single reuse is the primary source of inventions. For the impacts of technology networks' embeddedness, we find that network tie strength suppresses the growth of technological knowledge domains, and network status and convergence both facilitate the growth of technological knowledge domains. We expect that this study will provide some enlightenment for inventing or creating new knowledge in emerging fields in complex technological environment.

| Summary/Abstract |
With the deepening of China's innovation system reform entering into the 21st century, its functionality has received considerable attention in both academic and policy-making contexts. However, it has not been fully uncovered yet in a more systematic and practical manner possibly due to theoretical or methodological reasons. In this study, a structural approach with partial least squares is introduced to incorporate various functional constructs together determining the performance of innovation systems into an integrated path framework based on the extended framework of Romer's idea production function. By constructing a rich province-year panel dataset over the 10th five-year plan period of China, we use the novel analytical framework to detect and untangle the periodically operating state of China's regional innovation systems (RISs) in terms of the effectiveness of functional constructs shaping and influencing the innovation process. The examination results show that China's RISs perform well in terms of the performance of most functional constructs except for "innovation linkage" as well as "innovation sophistication". With respect to the interactive effects between the contextual innovation environment and the innovation process, however, China's RISs perform poorly from the perspective of system thinking.

| Summary/Abstract |
The USA is a leading country while China is an up-and-coming one in nanotechnology. We carried out a cross-country comparative study on policy and innovation of the two countries in subset nanoenergy field. They both created favorable policy environments for nanotechnology involving applications of nanotechnology in the energy sector. However, Chinese policy deployments for nanotechnology lack coordinated arrangements and effective assessment mechanisms. China performs better than the USA in technological quantity, but weaker in technological influence. The USA expresses an industry-oriented model in nanoenergy technological research and development, but China exhibits a university-and-institute-oriented model. Interorganizational collaboration relationships in the two countries are both still very rare and have huge development space. They both have a long way to go in converting their technological achievements into commercial products, especially China. Finally, we provide the policy implications of this study. In particular, the Chinese government should strengthen its efforts in policies by changing the national S&T evaluation system to set up the basic idea that quality is better than quantity in order to raise the original innovation motivations of innovators.

| Summary/Abstract |
The purpose of this paper is to analyze the technological system of Chinese manufacturing. The input-output method and network analysis are applied to investigate the structure and performance at the system level and the role of each sector at the individual level in 1997 and 2002. Firstly, the R&D-flow matrices for per unit output are constructed to examine the technology intensity and constitution of each sector. And then they are combined with the economic size and R&D investment structure in order to have a more comprehensive understanding of the system at the gross level, and reveal the main technology diffusion providers, acquirers and techno-economic flows between sectors. Results of both years show that the R&D performance and technology providing for diffusion are more concentrated than technology acquiring, and this difference becomes even greater in 2002. There are fewer sectors which act as main technology diffusion sources while more sectors participate as acquirers of technology diffusion. The techno-economic flows have high dependence on a few traditional sectors and the contribution of high-tech sectors such as ICT is quite limited.
