430074,China;2.School of Geography and Information Engineering,China University of Geosciences,Wuhan 430074,China Abstract:Suitable spatial morphology of cultivated land is a basic requirement for sustaining agricultural economic development in mountainous areas.Coordinated development effi-ciency of cultivated land spatial morphology and agricultural economy(CECA)is of great practical significance to measure the efficiency of cultivated land use,and thereby promote regional rural revitalization.However,few studies to date have focused on coordinated de-velopment efficiency between cultivated land use and agricultural economy in mountainous areas from the perspective of cultivated land spatial morphology.Thus,the present study explores CECA with this focus using the data envelopment analysis method,and analyzes the key influencing factors via a geographical detector model in 16 counties in western Hubei province.The results show the following:(1)CECA exhibits significant spatial heterogeneity that is high in the south of the study area and low in the north;(2)scale efficiency is the pri-mary limiting factor for CECA;(3)the insufficient output of cultivated land use mainly restricts CECA in the south of the study area,while individual county in the north suffered from input redundancy and insufficient output;and(4)population density in the southern region has the most significant effect on CECA,and gross domestic product has the greatest impact in the northern region.The results contribute to the derivation of specific measures by which to promote cultivated land use efficiency and sustainable development of the social economy.Keywords:cultivated land spatial morphology;agricultural economy;data envelopment analysis;geographical

revitalization is an important problem that needs to be solved as a Received:2022-05-07 Accepted:2022-09-26 Foundation:National Natural Science Foundation of China,No.71804168.Author:Xiang

Journal of Geographical Sciences matter of urgency(Huang et al.,2020).Underdeveloped areas in China are mostly concen-trated in rural areas,which have a complex topography,inefficient transportation,underde-veloped science and technology and relatively poor resource endowments.Such aspects have become important bottlenecks to economic development(Xiang et al.,2019b;Zhang et al.,2019).In addition,there has been an increasing flow in recent years of young labor into the cities(Qin and Liao,2016).This has led to an increasing number of vacant houses and abandoned cultivated land,leading to sluggish social and economic development in un-derdeveloped areas(Long et al.,2012;Li et al.,2014).In response to this problem,China has implemented vigorous strategies of“targeted poverty reduction”and“rural revitaliza-tion”to promote the economic development of these areas in a holistic manner(Lo et al.,2016;Guo et al.,2019;Yin et al.,2019).In this context,an important issue to promote regional socioeconomic development is how to improve the agricultural economy by en-hancing their vitality and self-hematopoiesis,for instance by optimizing their cultivated land spatial morphology.Central to this issue is the coordinated development efficiency between cultivated land spatial morphology and agricultural economy(in abbreviated form,CECA),as understanding this aspect is vital to improving cultivated land use efficiency and ensuring the sustainable development of the agricultural economy that means the economic develop-ment caused by agricultural production.Due to differences in the spatial topography,socioeconomic development status,science and technology level,and population flow across underdeveloped areas,the spatial mor-phology of cultivated land varies significantly(Guo and Liu,2022).Suitable spatial mor-phology of cultivated land is required in order to promote effective utilization of cultivated land and agricultural economic development.Scholars have carried out extensive research on cultivated land spatial morphology,mainly focusing on dominant morphology and reces-sive morphology(Long and Qu,2018;Ma et al.,2020),and functional morphology and spatial morphology(Song and Li,2019;Xiang et al.,2019b).Spatial morphology mainly refers to
