It is of great theoretical and practical significance to achieve high-quality development that promotes the transformation of digestion, absorption, and re-innovation to an independent innovation model, actively participating in the restructuring of the industrial chain, and enhancing the status of the Yangtze River Delta in the global innovation chain. This study constructs a tripartite evolutionary game model of collaborative innovation led by the government, participated by upstream enterprises and downstream enterprises. Moreover, this article analyzes the strategic choices of the tripartite entities in the process of collaborative innovation, and the simulation analyzes the influencing factors of the government, upstream enterprises, and downstream enterprises’ collaborative innovation strategy selection. The results indicate that the government, upstream enterprises, and downstream enterprises have different degrees of influence on each other’s willingness to participate. In addition, the analysis proves that government policy support and financial support have different impacts on upstream enterprises and downstream enterprises.

Abstract The gravity model is applied to construct a collaborative innovation network between cities in the Yangtze River Delta, analyzes its structural characteristics and evolution from a network perspective, and proposes development strategies. This will help optimize the network structure of collaborative innovation among cities in the Yangtze River Delta, improve the efficiency of collaborative innovation, and promote their innovation level together. Based on the data of urban innovation indexes in 2006, 2011 and 2016, this paper reveals the structural characteristics and evolution of the collaborative innovation network between cities in the Yangtze River Delta, and puts forward corresponding development strategies. The findings are as follows: (1) The overall innovation capability of cities in the Yangtze River Delta has been continuously improved, and the strength of collaborative innovation links between cities has slowly increased. (2) The innovation development of cities in the Yangtze River Delta is unbalanced and asymmetrical. The network presents a significant “core-periphery” spatial structure and a “multi-center, multi-level” pattern, and central cities drive the development of surrounding cities. (3) A reasonable regional innovation community should be constructed from the perspectives of spatial coordination, innovation industry chain integration and resource sharing, and the collaborative innovation network should be optimized.

Potentially toxic elements (PTEs) pollution in the agricultural soil of China, especially in developed regions such as the Yangtze River Delta (YRD) in eastern China, has received increasing attention. However, there are few studies on the long-term assessment of soil pollution by PTEs over large regions. Therefore, in this study, a meta-analysis was conducted to evaluate the current state and temporal trend of PTEs pollution in the agricultural land of the Yangtze River Delta. Based on a review of 118 studies published between 1993 and 2020, the average concentrations of Cd, Hg, As, Pb, Cr, Cu, Zn, and Ni were found to be 0.25 mg kg−1, 0.14 mg kg−1, 8.14 mg kg−1, 32.32 mg kg−1, 68.84 mg kg−1, 32.58 mg kg−1, 92.35 mg kg−1, and 29.30 mg kg−1, respectively. Among these elements, only Cd and Hg showed significant accumulation compared with their background values. The eastern Yangtze River Delta showed a relatively high ecological risk due to intensive industrial activities. The contents of Cd, Pb, and Zn in soil showed an increasing trend from 1993 to 2000 and then showed a decreasing trend. The results obtained from this study will provide guidance for the prevention and control of soil pollution in the Yangtze River Delta.

Interaction Relationship

In recent years, the impact of land-use systems on global climate change has become increasingly significant, and land-use change has become a hot issue of concern to academics, both within China and abroad. Urbanization, as an important socioeconomic factor, plays a vital role in promoting land-use transition, which also shows a significant spatial dependence on urbanization. This paper constructs a theoretical framework for the interaction relationship between urbanization and land-use transition, taking the Yangtze River Delta as an example, and measures the level of urbanization from the perspective of population urbanization, economic urbanization and social urbanization, while also evaluating the level of land-use morphologies from the perspective of dominant and recessive morphologies of land-use. We construct a PVAR model and coupled coordination model based on the calculated indexes for empirical analysis. The results show that the relationship between urbanization and land-use transition is not a simple linear relationship, but tends to be complex with the process of urbanization, and reasonable urbanization and land-use morphologies will promote further benign coupling in the system. By analyzing the interaction relationship between urbanization and land-use transition, this study enriches the study of land-use change and provides new pathways for thinking about how to promote high-quality urbanization.
