Agricultural production faces the dual challenge of increasing output while ensuring efficient resource utilization and environmental sustainability amid escalating global climate change relentless increases in human demand. This study used provincial panel data from China 2001 to 2022 address these challenges. It systematically evaluated dynamic evolution agricultural green total factor productivity (AGTFP) by selecting “resources” “energy” as core input factors adopting a dual-output approach focused on “economic” “low-carbon” outcomes. thoroughly analyzed synergistic mechanisms such natural endowment, technology, economic development, regulation, exploring their impact AGTFP enhancement through innovative application fuzzy-set qualitative comparative analysis (fsQCA) method. There was significant upward trend across China, indicating notable progress development. Additionally, three pathways promoting improvement were identified: resource–economy-driven, technology–policy-guided, multifactor-synergy. Simultaneously, two modes constraining uncovered: economy–policy suppression capital–economy suppression, highlighting pivotal role regional development conditionality converting advantages. Moreover, contributions exhibited temporal dynamics. Major events, 2008 financial crisis policy shifts, including 2012 “Ecological Civilization” strategy, significantly altered effectiveness existing configurations. Our heterogeneity revealed distinct geographical patterns, with resource–economy-driven model predominantly observed central regions technology–policy-guided multi-factor-synergy models more prevalent eastern regions. These findings highlight importance formulating differentiated policies tailored specific needs stages different Specifically, enhancing synergy between management optimizing technology–policy integration, coordinated multisectoral are critical fostering sustainable practices. research provides crucial empirical evidence for shaping targeted that can drive diverse contexts.

The global consensus to move towards carbon neutrality has been growing amidst turbulence, and the issue of emissions an unavoidable topic for achieving goal neutrality. introduction microalgae photosynthetic sequestration technology optimizes culture environment through hydrodynamics enhances efficiency light dioxide transfer, thus increasing rate photosynthesis effect microalgae. Based on biomechanical perspective, this study constructed a three-party dynamic evolution game model including agricultural subjects, enterprises local governments, analyzed mechanism by microalgae, financing subsidy system trading mechanism, explored strategic choices behavioral process subjects in face different policy incentives, verified conclusions numerical simulation analysis. shows that: (1) implementation financial policies governments significantly increases willingness producers apply technology, accelerating emission reduction; (2) integration energy industry market is conducive generation renewable energy, realizes win-win situation government’s environmental benefits enterprise’s economic benefits; (3) adoption promotion virtuous cycle soil microbial communities realization crop income. This evaluates potential impacts combinations reduction based which can help promote application reduction.

Introduction The marine economy has played an important role in stabilizing national economic growth and ensuring security. Achieving high-quality sustainable development of the is a strategic task for China to build maritime power. Confronting various risk factors such as financial crises, natural disasters, geopolitical conflicts, industrial transformation, public health security, etc., resilience (MER) received widespread attention recent years considered be crucial economy. Methods This study takes 11 coastal provinces cases, integrates 6 condition variables by building Resistance capability-Recovery capability-Renewal capability (3R) configuration model, uses fuzzy-set qualitative comparative analysis (fsQCA) approach empirically explore effect between multiple land MER. Results discussion (1) None conditions three dimensions resistance capability, recovery renewal alone constitute necessary strong or weak MER, indicating that single explanatory power MER; (2) There are two configurations MER: Strong Resistance-Recovery Type Comprehensive Type. Industrial structure, governmental digital core MER configurations; (3) four configurations: Weak Type, Recovery-Renewal I, II. may expand research scope influencing enriching perspective land-sea integration, well providing decision-makers with practical policy implications.
