The Regional Comprehensive Economic Partnership(RCEP)has created favorable conditions for building deeply integrated agricultural value chains(AVC)in *** on the RCEP agreement,this study employed the global trade analysis project(GTAP)model to evaluate the impact of RCEP on AVC of member countries in terms of time,tariff reduction,and reduction of non-tariff barriers(NTB).The results indicate that(1)the implementation of RCEP boosts the value-added to agricultural exports for most member countries,particularly in competitive industries;(2)the increase in domestic production and processing capacity,reflected in domestic value-added(DVA),is the primary factor driving the rise in the value-added of agricultural exports across various industries of member countries;(3)RCEP enhances the participation of most regional countries in AVC,with varying impacts on AVC positioning,thereby fostering regional AvC development;and(4)RCEP has a positive effect on AVC indicators both in the short and long term,with the effect becoming more pronounced over ***,reducing NTB enhances the positive effects of tariff reductions on AVC *** on the analyses,the following recommendations are proposed:(1)Leverage the development opportunities arising from RCEP implementation to enhance the agricultural DVA;(2)capitalize on cooperative opportunities created by RCEP to build cohesive regional AVC;and(3)prioritize the effective implementation of RCEP'shigh-qualityrules.

Stanford type A aortic dissection(STAAD/AD)is a degenerative aortic remodeling disease with an extremely high mortality rate and poor prognosis[1,2].Dissections can be classified into acute(90 d)stages depending on the time interval between the onset of initial symptoms and presentations[3].Patients who survive the acute phase progress to subacute and ultimately chronic stages[4,5].

Large Banks and Systemic Risk:Insights from a Mean-Field Game Model

引用

Journal of Systems Science & Complexity 2025年第01期 460-494页

作者： CHANG Yuanyuan FIROOZI Dena BENATIA David department of Decision Sciences HEC Montréal department of Applied economics HEC Montréal

This paper presents a dynamic game framework to analyze the role of large banks in interbank markets. By extending existing models, a large bank is incorporated as a dynamic decision-maker interacting with multiple small banks. Using the mean-field game methodology and convex analysis, best-response trading strategies are derived, leading to an approximate equilibrium for the interbank market. The influence of the large bank is investigated on the market stability by examining individual default probabilities and systemic risk, through the use of Monte Carlo simulations. The proposed findings reveal that, when the size of the major bank is not excessively large, it can positively contribute to market stability. However, there is also the potential for negative spillover effects in the event of default, leading to an increase in systemic risk. The magnitude of this impact is further influenced by the size and trading rate of the major bank. Overall, this study provides valuable insights into the management of systemic risk in interbank markets.

Spatio-temporal evolution of complex agricultural land use and its drivers in a super-large irrigation district (Hetao) of the upper Yellow River Basin (2000–2021)

引用

Journal of Geographical Sciences 2025年第2期35卷 273-301页

作者： LI Xinyi SUN Chen XIAO Xue LI Zhengzhong MA Xin WANG Jun XU Xu Chinese-Israeli International Center for Research and Training in Agriculture College of Water Resources &Civil Engineering China Agricultural University Institute of Environment and Sustainable Development in Agriculture Chinese Academy of Agricultural Sciences Shahaoqu Experimental Station Jiefangzha Department Inner Mongolia Hetao Irrigation District Water Resources Development Center Water Resources Research Institute of Inner Mongolia College of economics & Management China Agricultural University

Accurate spatio-temporal land cover information in agricultural irrigation districts is crucial for effective agricultural management and crop production. Therefore, a spectralphenological-based land cover classification(SPLC) method combined with a fusion model(flexible spatiotemporal data fusion, FSDAF)(abbreviated as SPLC-F) was proposed to map multi-year land cover and crop type(LC-CT) distribution in agricultural irrigated areas with complex landscapes and cropping system, using time series optical images(Landsat and MODIS). The SPLC-F method was well validated and applied in a super-large irrigated area(Hetao) of the upper Yellow River Basin(YRB). Results showed that the SPLC-F method had a satisfactory performance in producing long-term LC-CT maps in Hetao, without the requirement of field sampling. Then, the spatio-temporal variation and the driving factors of the cropping systems were further analyzed with the aid of detailed household surveys and statistics. We clarified that irrigation and salinity conditions were the main factors that had impacts on crop spatial distribution in the upper YRB. Investment costs, market demand, and crop price are the main driving factors in determining the temporal variations in cropping distribution. Overall, this study provided essential multi-year LC-CT maps for sustainable management of agriculture, eco-environments, and food security in the upper YRB.
