In this model, each cooperative agent and noncooperative agent are endowed with integer values of cooperative spirits and nonco- operative spirits, respectively. The cooperative spirits of a cooperative agent aggregate and the noncooperative spirits of a noncooperative agent aggregate change via four competing microscopic reaction schemes： the win-win reaction between two cooperative agents, the lose-lose reaction between two noncooperative agents, the win-lose reaction between a coop- erative agent and a noncooperative agent （equivalent to the migration of spirits from cooperative agents to noncooperative agents）, and the cooperative agent catalyzed decline of noncooperative spirits. Based on the generalized Smoluchowski＇s rate equation approach, we investigate the dynamic evolution behaviors such as the total cooperative spirits of all coop- erative agents and the total noncooperative spirits of all noncooperative agents. The effects of the three main groups of competition on the dynamic evolution are revealed. These include： （i） the competition between the lose-lose reaction and the win-lose reaction, which gives rise to respectively the decrease and increase in the noncooperative agent spirits; （ii） the competition between the win-win reaction and the win-lose reaction, which gives rise to respectively the increase and decrease in the cooperative agent spirits; （iii） the competition between the win-lose reaction and the catalyzed-decline reaction, which gives rise to respectively the increase and decrease in the noncooperative agent spirits.展开更多

It includes: optimize and integrate strategic resources through connectivity, cultivate export-oriented cultural enterprises to promote the main body of the industry, optimize the structure of cultural trade by expanding cultural services exports, and build win-win cooperation networks through the connections between Silk Road Cities. This will both contribute to the global distribution and resource allocation of China's culture industry, and benefit the construction of mutually beneficial and cooperative international culture industry communities, so the countries and people of the Belt and Road regions can share their cultural wealth.展开更多

Taking the Jiangxi Academy of Sciences （JXAS） as an example, we first explain how to apply this framework to analyze the strengths and weaknesses of PASs in China. Then, we compare the results of all 17 PASs in order to get a comprehensive understanding of their competitiveness.Findings： Our results show the development path, current status, innovation advantages, and weaknesses of JXAS very clearly. Based on our comparative analysis, we ranked the 17 PASs from the perspective of different dimensions, by which their competitiveness strengths and weaknesses can be highlighted for improvement.Research limitations： In this analysis, we did not take S＆T policies, S＆T systems, or historical factors into consideration. Thus, we may have ignored the influence of the soft individual differences of different PASs in China..Practical implications： The evaluation index developed in this paper provides a useful insight into an analytical method that can be used by PASs or other provincial research institutions （PRIs） to assess their competitiveness.Originality/value： Compared with existing evaluation frameworks, our method has two main characteristics： First, we added three new dimensions, including the PASs＇ applicable research outputs, regional contributions, and comparative advantages; second, we conducted a comparative analysis of local research institutes in their different advantaged industrial areas, which makes our analytical method more comprehensive for local research institutions.展开更多
