China: Building an innovator
When it comes to translating its own research into practical applications, China falls short. A forum in Shanghai put the spotlight on ambitious plans to accelerate the process.
Patent statistics: A good indicator for innovation in China? Patent subsidy program impacts on patent quality
Using a merged dataset of Chinese patent data and industrial survey data, we make a bibliometric analysis of patenting activities of Chinese large and medium-sized enterprises under local patent subsidy programs and test whether patent statistics are a good indicator of innovation in China. Our empirical results show that patent count is correlated with R&D input and financial output, which suggests that patent statistics are meaningful indicators. However, patent subsidy programs increase patent counts more than 30%. We emphasize the necessity of adjustments and provide a novel method of using the number of nouns in claims to quantify the claim scope, thereby overcoming the shortcomings of Chinese patent data that have no citations or lack well-documented patent claim information. We extend prior studies on patent subsidy programs by providing a detailed clarification of policy designs and their impacts and by evaluating policy impacts on both the quantity and quality of patent applications.
12.2: Enhanced Electron Emission of the Cone‐Shaped Emitters with Carbon Nanostructures
We developed novel cone‐shaped emitters with individual carbon nanotips using the resist‐assisted patterning process. The novel cone‐shaped nanotip emitters were arranged in an array with many nano emitters in pre‐patterned diameters of 3 μm. The cone‐shaped nanotip emitters consist of a number of carbon‐based nanostructures such as nanotubes and/or nanofibers with silicon and nitrogen elements at the periphery of each element. The cone‐shaped nano‐emitters strongly adhered to the substrate due to the large area bottom contact which is covered with diffused silicon elements. The growth mechanism and enhanced electron emission of cone‐shaped nanotip emitters was discussed.
