China views the development of sustainable agriculture as a crucial aspect of agricultural development. Using green agriculture patents from 1998 to 2021, this paper analyzes the spatial and temporal distribution of patent numbers and investigates the IPC co-occurrence network. The findings are as follows. First, the number of patents for green agriculture in mainland China has increased significantly. From 2010 to 2015, the number of patents reached its highest point. Second, the spatial distribution of green agriculture patents is quite uneven, particularly in Heilongjiang province, which has the largest grain production and the lowest patent output level. Third, while the majority of IPC subclasses are well-developed, some are unevenly developed. In China, popular fields include seed breeding, planting, and organic fertilizers. This research aims to present empirical evidence for the future layout of green agriculture in China and the development of green agriculture in other developing countries.

Purpose: The academic experience of top management team (TMT) has a positive impact on firms' innovation performance. However, existing studies predominantly focus on the educational qualifications and institutional prestige of TMT, failing to comprehensively evaluate whether TMT possess genuine academic experience and the role of academic competence. This article aims to examine whether TMT academic competence has a potential influence on firm innovation performance and to understand the mechanisms behind this relationship. Design/methodology/approach: Using firm-level metrics of Chinese listed firms and TMT scholarly publication data spanning 2000–2021, this paper investigates whether TMT academic competence can promote firms' innovation performance and conducts a moderated mediating effect analysis. Findings: (1) Academic competence of TMT can contribute positively to firms’ innovation performance; (2) university–industry collaboration partially mediates this relationship; (3) the mediating effect is enhanced by cognitive proximity and (4) distance proximity does not diminish the mediating effect. Research limitations/implications: Outcome of this study can assist academia in further understanding the impacts of TMT on firm innovation and aid government in promoting university–industry collaboration. Simultaneously, it can help firms adjust their TMT selection and training strategies to enhance innovation performance. Originality/value: This article, as the first to construct an index of academic competence and to explore whether it has an impact on firms' innovation performance and its inherent mechanism, can provide a new research perspective for the study of the impact of TMT's characteristics on firms' innovation.
