High-quality development of water conservancy (HDWC) is of critical value for safeguarding the stability of production systems, livelihoods, and ecosystems. As the digital revolution intersects with China’s “dual carbon” targets, development of water conservancy must transition from traditional engineering approaches to data-driven ecological models. Drawing on institutional logic theory and employing dynamic qualitative comparative analysis across 30 Chinese provinces, this study examines how digital ecology facilitates the HDWC. The findings reveal that none of digital government, digital infrastructure, digital economy, digital capability, or digital society constitutes a necessary condition for the HDWC. Instead, it is the result of the combined effects of multiple institutional logics. Five configurations leading to HDWC are identified and categorized into four types: government-market-driven model, government-market-society-driven model, market-society-driven model, and government-society-driven model. The consistency of the configurations significantly increased during the study period. Furthermore, their distribution showed substantial regional differences. There are two configurations that inhibit the HDWC, namely the government-market-absence type and the market-society-absence type. Digital society emerges as a critical factor. This research uncovers multiple pathways through which digital ecology can empower HDWC, providing valuable insights for optimizing regional digital environments.

Recent research indicates that the relationship between state ownership, firm size, and technological innovation outcomes in Chinese firms is a complex and intriguing topic. However, we propose a new perspective based on institutional complexity and examine the combined effects of these two factors. By considering the interplay between the economic efficiency rationale and the institutional logic associated with state ownership and firm size within the context of Chinese firms, we argue that the effects of state ownership and firm size can counterbalance each other. In order to test our hypotheses, we analyze a sample of 385 publicly listed firms spanning the period from 2015 to 2019. The findings reveal that while state ownership and firm size individually exert a negative influence on both exploratory and exploitative innovation in Chinese firms, their interaction actually yields a positive impact. This study contributes to our comprehension of how state ownership influences exploratory and exploitative innovation in the presence of competing institutional logics, as well as the contingent effect of firm size.
