摘要: | 自20世紀80年代初以來,中國經歷了快速的經濟成長及城市化進程,但同時也面臨嚴重的環境問題。為了解決環境問題並提升農業的可持續或永續發展(Sustainable Development),近年來,中國政府積極推動有機農業的發展。根據2012年至2022年的數據,中國有機農地的佔比從0.48%增長到3.14%,其中稻米、穀物、蔬菜、水果及茶葉等有機農作物的佔比較高。本研究利用中國2012-2022年的省級數據,運用ArcGIS軟體分析中國五大有機農作物的地理分佈狀況。同時,本研究以建構的空間統計模型,分析了影響有機農業發展以及有機茶葉空間效應的重要因子。相較於過去的研究,本研究的主要特點在於同時考慮不同有機農作物的地理分佈特性,並運用固定面板模型(Fixed-Effects Panel Model)與本研究使用雙固定空間杜賓模型(Double Fixed-Effects Spatial Durbin Model, Double FE-SDM)來探討五種主要有機農產品的採用率,並探討其主要影響因素。
研究結果表示:(1)中國有機農業的發展呈現地理特徵上的差異性,即空間異質性(Spatial Heterogeneity),同時不同地區之間存在相互影響,即空間依賴性(Spatial Dependency)。此外,不同有機農作物在地理上呈現不同的聚集現象,即存在冷熱點區域的落點差異。(2)居民收入水平、高速公路的公里數等因素對五種有機農作物的發展具有正向且顯著的影響。(3)有機茶葉的發展主要受到當地區位因素的直接影響,同時也決定於鄰域地區的空間溢出效應 (Spatial Spillover Effects)。此外,本研究發現少數民族佔轄區總人口比例、農業就業人數、農業從業人員的平均受教育年限等因素,其在空間上皆產生顯著的溢出效應。本研究不僅可以填補過往相關文獻的缺口,對於中國未來有機農業發展的相關政策制定具有重要意義,研究發現亦有助於改善政府推動有機農業政策的成效。 Since the early 1980s, China has undergone rapid economic growth and urbanization, but this has also brought about serious environmental issues. To tackle these challenges and promote sustainable agricultural practices, the Chinese government has been actively advocating and supporting the growth of organic agriculture. According to data from 2012 to 2022, the proportion of organic farmland in China has increased from 0.48% to 3.14%, with higher proportions observed for organic crops such as rice, grains, vegetables, fruits, and tea. In this study, we utilize provincial-level data spanning from 2012 to 2022 and employ ArcGIS software to conduct a spatial analysis of the geographical distribution of the five major organic crops in China. Furthermore, we construct a spatial econometric model to investigate the determinants influencing the development of organic agriculture and to explore the spatial effects of organic tea production. In comparison to previous studies, this research distinguishes itself by simultaneously considering the geographical distribution characteristics of different organic crops and employing fixed effects panel models and spatial Durbin models to analyze the adoption rates of various agricultural products. The findings reveal that (1) organic agriculture in China exhibits spatial heterogeneity and spatial dependence, with different organic crops showing varying patterns of spatial clustering or hotspots; (2) factors such as residents' income levels and the length of highways positively impact the development of the five organic crops; (3) the growth and progress of organic tea cultivation are significantly shaped by various localized factors, while also being subject to spatial spillover effects from neighboring areas, with factors such as the proportion of minority population, agricultural employment, and average education level of agricultural workers displaying significant spatial spillover effects. This study provides valuable insights for the formulation of future policies related to organic agriculture development and contributes to enhancing the effectiveness of government initiatives in promoting organic agriculture. |
