... This global trend is keenly observed in China, where the economy has transitioned to a "new normal", shifting from rapid growth to prioritizing high-quality development [4][5][6]. In this evolved economic landscape, UAs are not merely engines of economic development and urbanization [7][8][9]; they also serve as crucial connectors between domestic and international economies [10][11][12], fostering international cooperation and competition [13][14][15]. Building on this foundational understanding, a new development paradigm emerges where the domestic and international markets can boost each other, with the domestic market as the mainstay [16]. Within this framework, UAs have gained a strategic prominence [17], becoming instrumental in driving regional economic development [18] and social progress. ...
Urban agglomerations (UAs), which serve as pivotal hubs for economic and innovative convergence, play a crucial role in enhancing internal circulation and strengthening external linkages. This study utilizes the China city-level multi-regional input-output tables, incorporating the Dagum Gini coefficient and kernel density estimation methods, to perform a thorough quantitative analysis. Disparities within the national and global value chains ("dual value chains") of Chinese UAs from 2012 to 2017 were assessed. Additionally, the logarithmic mean Divisia index (LMDI) method was applied to disaggregate the drivers of both national and global intermediate inputs (NII and GII). The study’s key findings include the following: (1) The national value chain (NVC) within UAs exhibits robust growth, contrasting with the decline in the global value chain (GVC). (2) The inter-UA disparity contribution rate significantly surpasses the combined rates of intra-UA contribution and super-variation density. (3) Distinct evolutionary peak trends are discerned among various UAs within the "dual value chains", highlighting diverse spatial polarization characteristics and expansiveness. (4) The growth of the NVC has transitioned from a negative to a positive impact on NII, while the decline in GVC has substantially counteracted GII growth. Economic and demographic factors notably drive positive improvements in both NII and GII, whereas the efficiency of outflows presents a negative driving effect. Based on these findings, this study offers strategic recommendations to facilitate the effective integration of UAs into the new development paradigm, thereby providing a scientific basis for related decision-making processes.
... Moreover, the HH cluster area of the Tianjin area also declined obviously (Figure 4a). This may be due to Beijing's implementation of a series of administrative policies to encourage the reduction of the secondary industry and the development of the tertiary industry before the secondary industry was fully developed and transferred to neighboring cities, resulting in a delay in the integration process and development of the Beijing-Tianjin-Hebei agglomeration [43,44]. In the northern coastal areas, Liaoning Province exhibited the most severe area growth in the LL cluster by 2021, while the HH cluster area around Shenyang and Dalian was significantly reduced (Figure 4a), meaning that the economic growth of the region was low during this period. ...
The joint construction of the Silk Road Economic Belt and the 21st Century Maritime Silk Road proposed by China has brought major development opportunities for the development of countries and regions along the routes. Traditional GDP statistics based on administrative units cannot describe the spatial differences of GDP within administrative units, which has certain limitations in exploring regional economic development analysis and supporting economic development decision making. Based on NPP-VIIRS luminous remote sensing data, land use data, and statistical yearbook data, this paper analyzes the spatial–temporal evolution pattern of economic level in China’s coastal economic belt from 2012 to 2021 using the Moran index and standard deviation ellipse. An unbalanced distribution of economic development are found along China coastal area and the economic gravity center moved southwest since the Belt and Road Initiative. The results show thatthe Yangtze River Delta was extremely active , and the economic growth of the south was better than that of the north. The grided GDP map presents more details of regional economic development, and provides an opportunity for further mechanisms exploration of the development process.
... However, with the urbanization of the population, humans have not paid enough attention to the land change caused by urbanization ). The population is gradually moving from the countryside to the city, and the land on which humans live is also changing, causing land urbanization such as the increase of cities and towns, the expansion of builtup areas, the changes in regional landscapes and land use types (Wang 2022;Li et al. 2019). From 2000 to 2022, the Responsible Editor: Philippe Garrigues growth rate of land urbanization (165.16%) was significantly higher than that of population urbanization (44.61%), while the area of construction land in China increased by 2.93×10 3 km 2 . ...
The rapid development of China’s new urbanization has created favorable conditions for economic growth and social development. Urbanization includes population urbanization and land urbanization, among which land urbanization leads to land ecological security problems. At present, there is a lack of comprehensive understanding of land ecological security in China’s new urbanization construction. This paper aims to fill the gap by systematically combing relevant literature on the connotation, status, and governance of land ecological security in China’s new urbanization. Literature review shows that China’s land ecological security is still at a low level, and the new urbanization construction has significant impacts on land ecological security. Land contamination is the most critical factor threatening land ecological security, and there are differences in the levels of land contamination and types of pollutants in different new urbanization construction forms. According to an example of land ecological security governance with enterprises as the main body and multiple subjects cooperating, the governance of land ecological security needs to integrate a variety of different subjects to coordinate governance. Future research directions should focus on the construction of land ecological security assessment index system, development of land contamination multi-level control technology, and construction of multi-subject collaborative governance model with “government-enterprise-social organization-residents.”
... Advanced regional planning strategies promote inter-regional economic development, population flow, and industrial cooperation with higher tendency to agglomeration and diffusion of regional industries in geographical space (Wang 2022b). Currently, there is a trend toward gathering high-and middle-end manufacturing and service industries in the agglomeration megacity, while labor-intensive middle-and low-end processing industries and agriculture move to its satellite cities. ...
The advancement of effective spatial planning to support sustainable development and inter-regional cooperation has become an issue of serious concern for regional authorities. Spatial planning research helps to identify economic clusters and analyze their changing spatial patterns, which is important for understanding regional economic space dynamics and potential inter-regional cooperation. To support decision-makers in the development of efficient plans of spatial development encompassing the identification of the best-suited territories, a combined Geographic Information System (GIS) based approach to interpret qualitatively expressed multiple socio-economic scenarios in quantitative map-based terms of graded suitability, and a formalized approach to the socio-economic evaluation of the territory is offered. Based on GIS technology coupled with integrated cellular automata decision analysis techniques, the study provides a method that performs socio-economic assessment of the study area according to the generated scenarios of regional spatial and socio-economic development. The proposed method is applied to Primorsky and Khabarovsk Krais, located in the Russian Far East. Socio-economic scenarios of spatial development initiated by investors and regional authorities were assessed and evaluated. The generated socio-economic scenarios illustrate how the unified set of spatial and socio-economic variables can be linked and used to gain insights into inter-regional socio-economic and spatial development. The application results demonstrate the advantage of the proposed method in identifying the best-suited unit areas for targeted regional development.
... The research content mainly includes the recognition, differentiation characteristics, evaluation index, and influence mechanism of "production-living-ecologica" functional space (Wang 2022a). At the level of research methods, the identification of multi-function of land use has changed from the traditional qualitative description to the quantitative measure constructed by multi-index system, mainly including comprehensive index, fuzzy comprehensive evaluation, grey correlation, and improved catastrophe progression (Wang 2022b). At the level of research scale, literatures based on traditional social statistics mainly focus on national, provincial, municipal, and other macrocategories (Xin et al. 2021). ...
Based on the land remote sensing monitoring data from 2000 to 2020, this paper quantitatively analyzed the spatio-temporal evolution of “production-living-ecological” functions and the geographical dominance degree of Liaoning Province using a geospatial model, and put forward some policy suggestions. The results showed that the living function area increased by 2957 km2, the ecological function area increased by 2011 km2, and the production function area was reduced by 4968 km2. The spatial distribution of production function was higher in the middle part, lower in the east and west, and the functional index was between 0.01 and 0.21. The living function level is distributed from east to west, and the function index decreases gradually from plain to surrounding mountains. There was a significant correlation between the level of ecological function and topography, and the functional index ranged from 0.01 to 0.65. The advantageous areas of production function are located in the central plain of Liaoning and Dalian, the advantageous areas of living function are located in the central part of Liaoning, and the advantageous areas of ecological function are located in the eastern and western parts of Liaoning. Social and economic level, natural ecological environment, and regional development policy are the important factors that affect the layout of “production-production-production” function. It is suggested that the provincial government should build a comprehensive management system across administrative regions, design the ecological and environmental protection policy framework of “production-living-ecological” function, and improve the ecological protection coordination mechanism.
... In some countries in Europe, and in the United States, a large number of rural populations have migrated to cities, causing agricultural land abandonment [3,4], and farmland marginalization has become a common phenomenon [5][6][7]. Rapid urbanization has profoundly affected agricultural production activities [8] and caused dramatic changes in land use [9,10]. Especially in metropolitan areas, the amount of farmland and production capacity has kept declining [11]. ...
Farmland is the most precious natural resource and the primary source of food for human beings. Urbanization not only occupies a large amount of farmland spatially, but also economically squeezes agricultural production, resulting in farmland marginalization and causing serious threats to food security. However, the manner in which rapid urbanization drives farmland marginalization in surrounding areas and the factors that might play a dominant role in this process remain elusive. Therefore, the present study considered rapidly urbanized regions of 128 county-level units in the Yangtze River Delta (YRD) of China from 2000 to 2020 as the study area. Methods such as spatial autocorrelation analysis, hotspot analysis, and multiple linear regression analysis were used to explore the spatiotemporal evolution characteristics and the driving factors of farmland marginalization. The results showed that: (i) the marginalization ratio of farmland in YRD from 2000 to 2020 was 31.34%, with a distinctly increasing trend, generally high in the central and southern and low in the north areas; (ii) marginalization exhibited different spatial agglomeration under different influencing factors: the economy-induced marginalization ratio was 23.19%, playing a dominant role, in general, distributed as high in the middle and low on the sides, while the nature-induced marginalization ratio was 8.15%, and in general, the spatial pattern shifted from discrete- to a clear- distribution of high in the south and low in the north; and, (iii) farmland area per capita, total power of agricultural machinery, GDP per capita and government farmland subsidies were the main factors driving farmland marginalization. In addition, nature-induced marginalization was primarily driven by economic level and topographical conditions, whereas economy-induced marginalization was primarily driven by production conditions. We suggest that in the future, corresponding policies and measures should be established to reduce farmland marginalization in rapidly urbanized areas and to ensure food security.
... At present, global urbanization has entered the track of rapid development and promoted the drastic transformation of land use in-depth and breadth (Wang et al., 2019;Wang, 2022). In particular, the rapid expansion of construction land brought by urbanization leads to the continuous decrease in cultivated land, which affects the structural changes of the agricultural supply-side and brings great challenges to food security. ...
Studying the internal relationship between urbanization process and cultivated land change can reveal the differential law of different urbanization processes and effectively protect cultivated land resources. Using the land-use change analysis method, this paper analyzed the quantity and quality change of cultivated land during the process of urbanization in the Bohai Rim region from 1990 to 2020 and explored its driving mechanism. The results show that the urbanization level in the Bohai Rim region increases by 31.06%, and 120 km² farmland will be occupied for every 1% increase in urbanization level. The level of urbanization is higher in Beijing and Tianjin, medium in Liaoning and Shandong, and lower in Hebei. The area of cultivated land decreased year by year, and the decrease in dry land was the largest, followed by paddy land. Hebei, Shandong, and Liaoning have a high contribution rate to the reduction in cultivated land around the Bohai Sea. Population urbanization, spatial urbanization, and other factors have a significant impact on the study area, while economic urbanization and life urbanization show different laws. It is suggested that the development of urbanization can be promoted in a timely and appropriate manner, and the harmonious development of urbanization can be promoted by optimizing the layout of land use and avoiding excessive occupation of cultivated land at the expense of food security and ecological environment.
In the context of accelerated globalization, intercity factor flows are becoming increasingly dependent on a reasonable and orderly spatial structure. Therefore, an in-depth study of the optimization and adjustment of spatial structure is essential for coordinated development. This study quantitatively evaluated urban development levels and introduced network analysis methods to analyse the spatial structure and robustness of development. The results indicated the following: (1) The urban development level in the Beijing-Tianjin-Hebei (BTH) region increased in all dimensions, and the transmission efficiency significantly improved. (2) The spatial structure of the BTH region has been relatively stable, as illustrated by the main pattern of the spatial distribution of central cities, with a trend towards contiguous development. (3) The ranking of network robustness is environment>society>economy, and the core network and key nodes are primarily located within the radiation of the three central cities of Beijing, Tianjin, and Shijiazhuang. (4) The coordinated development of the BTH region is effective but still needs to be optimized and adjusted, and the strategic significance of edge cities has not been completely exploited. This study aims to provide an emerging analytical perspective for optimizing regional spatial structure and promoting regional coordinated development.
Due to modernization and urbanization, traditional medicinal herbs and their associated knoweldge are under peril of being lost. The current study not only aimed to document the trend of herbal medicinal plant uitlization in District Lahore, Punjab, Pakistan, but also raised alarming concerns about the conservation of these medicinal herbs and traditional knowledge linked to them. The data were collected from local people, herbalists, and gardeners by using standard ethnobotanical methods, i.e., questionnaires and interviews. Results reported that a lower number of informants possessed medicinal herb knowledge and reported only 50 medicinal herbs from the study area. This is probably due to the impact of speedy industrilaization and alterations in human life patterns in the study area. Not only the traditional knowledge is under threat but also the medicinal herbs themselves. Most of the reported medicinal herbs were rare (45.10%), while only few (9.80%) were ranked as abundant in the study area. The herbs with more medicinal importance are mostly rare. This is because of their over usage by the local people. Both conservation approaches (in situ and ex situ conservation and cultivation practices) and resource management (good agricultural practices and sustainable use solutions) should be adequately taken into account for the sustainable use of medicinal plant resources.
