Abstract
The development of green transportation technologies in China has grown rapidly due to increasing concerns about climate change and environmental pollution. Collaboration innovations covering kinds of participating entities and various linked relationships have become one of the critical drivers for the transportation sector. Some researchers have analysed the collaborative innovation of scientific literature in this field. However, fewer studies have investigated the current performance of collaborative technology innovation represented by patents in the transportation sector. In this context, a research framework based on the social network analysis approach is proposed for collaboration green transportation technologies. The purpose of the research is to establish an analytical framework for the green transportation innovation network and seek the key collaboration activities and strategies. Subsequently, a collaborative innovation network based on the patent data of green transportation technologies was built and analysed. Especially, the innovation entities in the collaboration network are divided into four groups: business enterprises, individuals, universities, and research institutions, so that more detailed information in the network could be obtained. The results show that the proposed research framework based on patent data and social network analysis method helps examine the critical nodes and links in the network, as well as their types and characteristics of the collaboration network. The increasing number of green transportation technologies shows active cooperation in this field. The study also found that business enterprises node gradually plays a major role in cooperative innovation. The corresponding policy recommendations are also provided.
Highlights
Not surprisingly, China is growing into one of the world’s most crucial transportation market
The green transportation innovation activities represented by green transportation technologies (GTTs) and cooperative GTTs are active during the investigation period, especially for the significant growth of total GTTs
GTTs are the critical driving forces to promote the sustainable development of the transportation industry, in which technical collaboration plays an active role. is study presented the investigation of GTTs collaborative in China’s transportation sector based on the social network analysis method and GTTs patent data. e following conclusions are offered
Summary
China is growing into one of the world’s most crucial transportation market. A report conducted by Forbes.com shows that ten transportation enterprises in China made the Forbes Global 2000, with each rising significantly in rank Forbes Global 2000: the World’s Largest Transportation Companies 2018 (https://www.forbes.com/ sites/antoinegara/2018/06/06/forbes-global-2000-the-worldslargest-transportation-companies/#6e40011b100f). According to the World Bank database, China’s definite advantage in transportation infrastructure prompts its rank rise in the logistics performance index system. E latest report on the logistics performance index shows that China has become the top performer among upper-middle-income economies [1]. Based on the booming development of China’s transportation market, research on China’s GTTs is gradually rising. Wang et al [2] applied the transportation mode-technologyenergy-CO2 model to analyse the energy consumption and CO2 emissions in China’s transportation sector. Liu et al [4]
