摘要

绿色创新(GI)的空间分析是众多研究的重点。然而,对中国地理标志的多尺度演化模式分析和趋势预测研究较少。本文基于2000-2019年中国337个城市地理标志活动的多尺度分布及其演化特征,试图弥补这一研究空白。利用尺度方差和两阶段嵌套Theil分解方法,在区域、省、地级市等多个尺度上分析了中国地理指数的空间分布及其不平等。利用马尔可夫链和空间马尔可夫链分析了中国地理标志的动态演变,并对其长期发展进行了预测。研究结果表明,中国地理标志具有多尺度效应,对空间尺度变化高度敏感,在各个尺度上地理标志的空间差异显著减小。地理标志的时空演化受地理空间格局和空间尺度的双重影响,表现出“俱乐部收敛”效应,并有向更高邻近水平转移的趋势。这种影响在更大的范围内更为明显,但要转移到更高的层次却越来越具有挑战性。该研究还表明,随着时间的推移,中国的地理标志水平持续稳定增长。这些结果有助于更准确地认识地理标志发展的尺度,为优化中国地理标志空间结构、促进其发展提供科学依据和政策建议。

Dynamic evolution and trend prediction of multi-scale green innovation in China

Numerous studies deal with spatial analysis of green innovation (GI). However, researchers have paid limited attention to analyzing the multi-scale evolution patterns and predicting trends of GI in China. This paper seeks to address this research gap by examining the multi-scale distribution and evolutionary characteristics of GI activities based on the data from 337 cities in China during 2000–2019. We used scale variance and the two-stage nested Theil decomposition method to examine the spatial distribution and inequalities of GI in China at multiple scales, including regional, provincial, and prefectural. Additionally, we utilized the Markov chain and spatial Markov chain to explore the dynamic evolution of GI in China and predict its long-term development. The findings indicate that GI in China has a multi-scale effect and is highly sensitive to changes in spatial scale, with significant spatial differences of GI decreasing in each scale. Furthermore, the spatiotemporal evolution of GI is influenced by both geospatial patterns and spatial scales, exhibiting the “club convergence” effect and a tendency to transfer to higher levels of proximity. This effect is more pronounced on a larger scale, but it is increasingly challenging to transfer to higher levels. The study also indicates a steady and sustained growth of GI in China, which concentrates on higher levels over time. These results contribute to a more precise understanding of the scale at which GI develops and provide a scientific basis and policy suggestions for optimizing the spatial structure of GI and promoting its development in China.

期刊介绍: Geography and Sustainability serves as a central hub for interdisciplinary research and education aimed at promoting sustainable development from an integrated geography perspective. By bridging natural and human sciences, the journal fosters broader analysis and innovative thinking on global and regional sustainability issues. Geography and Sustainability welcomes original, high-quality research articles, review articles, short communications, technical comments, perspective articles and editorials on the following themes: Geographical Processes: Interactions with and between water, soil, atmosphere and the biosphere and their spatio-temporal variations; Human-Environmental Systems: Interactions between humans and the environment, resilience of socio-ecological systems and vulnerability; Ecosystem Services and Human Wellbeing: Ecosystem structure, processes, services and their linkages with human wellbeing; Sustainable Development: Theory, practice and critical challenges in sustainable development.
