Abstract ( 18 )
Science and technology innovation resources are the cornerstone of the regional innovation activities and play an important role in the regional economic development. The spatial distribution of the innovation resources is a focus of the economic and geographic studies. Based on the global and local autocorrelation methods, this paper studies the spatial distribution and the dynamic evolution of the scientific and technological innovation resources in the Yangtze River Delta regions from 2000 to 2018, including the R&D funds, the R&D personnel, and the innovative enterprises, and with the help of multiple regression models, analyzes the impact of the scientific and technological innovation resources on the regional innovation capability. It is shown that the Yangtze River Delta regions are rich in scientific and technological innovation resources, in a spatial “Z” pattern composed of Hefei, Nanjing, Suzhou, Shanghai, Hangzhou, and Ningbo among other cities, and the spatial difference shows a shrinking trend from 2000 to 2018. It is shown that the scientific and technological innovation resources play a significant role in promoting the regional innovation capacity. As the spatial distribution of the scientific and technological innovation resources becomes more and more balanced, the regional innovation capacity correspondingly presents a higher and higher trend. This paper puts forward some countermeasures and suggestions to promote the innovation and the development of the Yangtze River Delta regions.

Abstract ( 11 )
The pattern of several airports sharing a regional air transport market is getting more and more popular. Under the background of the rising of the urban agglomeration, this linkage pattern between the urban agglomeration and the airport clusters is formed generally in the world. This paper clarify the related concepts, such as the airport clusters and the multiairport region, then based on analyzing the development of the airport clusters in the Yangtze River Delta, we make the following four observations: the density is still lower than that of the mature airport clusters in the world, there are space imbalances between the airports and the cities, the coordination among the airports has not yet been formed, and the zero-sum thinking still exists. With the mature airport clusters as the benchmark, we analyze the airport density, the hierarchical system, the functional coordination and the regional governance in the world. Based on the above analysis, we put forward four suggestions as follows: firstly, the airport clusters in Shanghai metropolitan should lead the integration of Yangtze River Delta airports, with the airport density around Shanghai being improved. Secondly, the airport clusters in the main metropolitan areas, such as Nanjing and Hangzhou, will be the important points. Thirdly, it is urgent for the main hub-airports and the main metropolitan areas to take a diversified positioning strategy. Lastly, in the Yangtze River Delta, a trans-administrative-area governance organization should be established, for smooth communication and coordination among airports.

Abstract ( 14 )
As one of the leading technologies in the field of the biomass thermochemical treatment, the biomass microwave pyrolysis enjoys the advantages of fast reaction rate, easy control, safety and no pollution. However, there are some problems in the gas production, such as low yield and low calorific value, which seriously restricts the comprehensive and efficient utilization of the biomass energy. In this paper, the principle of the microwave-assisted pyrolysis is introduced. From the latest researches at home and abroad, four aspects of the microwave-assisted pyrolysis technology are highlighted: improving the gas production yield and the calorific value, effectively removing the tar, inhibiting the pollutant generation and reducing the system energy consumption. On this basis, the limitations of the tar model compounds and the problems in the tar conversion and removal are reviewed in detail. In view of the above problems, some scientific and reasonable suggestions are given. Combined with the development trend of the microwave pyrolysis gas production technology, the main development directions based on the future industrial applications such as accelerating the transformation from the theoretical and experimental research to the industrial application research are put forward.

Abstract ( 31 )
In order to reveal the characteristics of the bottleneck technique, with CNC machine tools as an example, using the case comparison methods, this paper analyzes the patent technology characteristics from a micro perspective based on the patentometrics. It is found that there is a gap between the scientific community and the industry in China. In general, the technology integration is complex and the patent value is in a low level, with weak competitiveness. The universities focus mainly on the CNC technology, with the technology system in a chain structure. The enterprise is mainly based on the machine tool manufacturing, with the technology system in a discrete structure. Japanese CNC machine tools are dominated by leading enterprises, and their patents show a high degree of technological concentration and relevance, with the overall technology system in a network structure of multiple technology cores, with a high degree of combination between the CNC and the manufacturing technology, and with high competitiveness. Finally, to strengthen the forging of the modern industrial chain and improve the safety and the reliability, it is recommended to build a technology ecosystem, with a bottleneck technique classification mechanism, and to reform the evaluation methods.

Abstract ( 20 )
SARS-CoV-2 and its variants, the viruses that cause the COVID-19 pandemic, have some new characteristics, such as the high transmissibility, the long incubation period, the sweeping susceptible population, and the high environmental endurance, so a key question of the pandemic management and control is monitoring the asymptomatic transmission in daily life and socioeconomic activities, especially, the wide-range of cross-region spread. These features pose a great challenge to the traditional pandemic management and control methods and the global public health surveillance and control system. An effective way to tackle this challenge is making full use of the digital technology in the pandemic management and control, and building an accurate regular epidemiological surveillance and smart pandemic management and control system. By analyzing the essential factors of a smart pandemic management and control system, the critical role of the federated learning in the practice of the cross-region and cross-department smart pandemic management and control is shown. According to the classifications of the cross-region pandemic-related data and the pandemic management and control requirements, the technology and the application of the cross-region smart pandemic management and control based on the federated learning are explored. This method is successfully applied in the COVID-19 pandemic management and control in Shanghai and Yangtze River Delta, providing a new pathway for the integrated decision-making and targeted pandemic management and control in China. This method is also instrumental for other countries in the pandemic management and control.

Abstract ( 17 )
The aging problem of China's population is becoming increasingly prominent. In view of that situation, some concerned parties for the country's aging problems proposed a "community nursing" model in consideration of the conditions in China and the wishes of many elderly. As an important part of the elderly's living space, the space of activities is important, and the elderly's activity characteristics and needs must be duly considered. With the typical space of activities for the aged in Fuzhou downtown as an example, the OD survey method and the related analysis methods are used to determine the factors affecting the number of visits to the space. The SD method and the Delphi method are used to determine the weights of these factors, which could eventually be used to build a clustered hierarchical analysis and evaluation model to evaluate various types of space of activities for the aged and provide relevant suggestions for the planning and the construction of similar kinds of space in communities.

Abstract ( 23 )
Since the implementation of the western development strategy, great achievements have been made in the economic development, the ecological environment and the social development of the western region. Compared with the southwest region, the development speed of the northwest region slowed down in recent ten years, and the gap between the northwest region and the southwest region has gradually widened. In 2020, the western region will usher in a new pattern of development. How to seize the opportunity, narrow the gap with the southwest region and achieve a high-quality development in the northwest region becomes an important research topic. Firstly, the toughness levels of the 30 cities above the prefecture level in Northwest China from 2008 to 2018 are comprehensively measured by the entropy method, and the difference of the toughness levels among the cities is analyzed. Finally, the main factors affecting the urban toughness are analyzed by the panel regression of the 30 cities, and the conclusions are as follows: (1) The gap of the urban resilience level in Northwest China is gradually widening, generally in the upper-middle level, mainly in the medium and relatively strong level, with few cities with a relatively strong resilience, mainly the provincial capitals, without a city with a strong resilience; (2) The great change in the ranking of some cities is mainly due to the different emphasis on the ecological environment. Strengthening the ecological protection makes the ranking of the cities in Gansu Province move upward, while the ranking of the cities in Shaanxi Province, due to the lack of the investment in the environmental governance, goes downward; (3) Due to the lack of cities with a high toughness level and the insufficient driving effect, the urban toughness in Northwest China shows a spatial distribution pattern of few very high level, some relatively high and low levels; (4) The administrative power and science and technology have the greatest influence on the urban resilience, followed by the economy and the openness. Although the financial and social aspects are very important, they do not have a great influence; (5) Administrative power and science and technology have a significant impact on the social resilience and the infrastructure resilience, a negative impact; the economic factors have a significant impact on the four subsystems, a positive impact; the openness has a positive impact on the economic resilience and the social resilience, while it has a negative impact on the ecological resilience and the infrastructure resilience.

Abstract ( 20 )
The organizational power of societies, associations, and research societies is directly related to the strategic planning goals of the China Association for Science and Technology. The concept of the organizational power is defined, and its constituent elements are identified in terms of introversion and extroversion according to the connotation of the organizational power, and at the same time the evidence-based research methods are adopted to analyze the six societies that are fighting the COVID-19 to collect evidence to verify whether the proposed constituent elements of the organizational power can be supported by the evidence. The research results show that the organizational power of societies, associations and research societies is composed of the knowledge guidance, the value realization of introversion, innovation and development, the service mobilization of extroversion, and the dual nature of the implementation supervision, the leadership standards, the cohesion and the collaboration, and the resource allocation. So the theoretical support is provided for the subsequent in-depth study of the cause and the effect of the organization of societies, associations and research societies.
