Spatial Equity Evaluation of Rural Eldercare Service Resources Based on Accessibility: A Case Study of Huanxian County of Gansu Province, China

Safeguarding the elderly population in the countryside is an inherent requirement for alleviating social conflicts in rural areas and effectively carrying out China’s Rural Revitalization.The existing spatial mismatch between rural elderly service facilities and pop-ulation distribution in China aggravates the imbalance of facility resource space,how to improve the accuracy of demand and supply results and better measuring the spatial fairness of elderly service is significant to realize the optimal allocation of rural elderly service.Based on the above,this study pays attention to the refined needs of the elderly population,and focuses on the spatial equity of the rural elderly facilities,to make up for the short boards of the basic public services in the countryside and realize the all-round rural revitalization.This study takes Huanxian County in the hilly loess area of Longdong,China as an example and explores the spatial equity of rural elderly services by using the Urban Spatial Network Analysis(UNA)to measure the accessible quantity and supply capacity of elderly services.The results found that there were 553 rural eldercare service facilities in Huanxian County,including 285 eldercare facilities and 268 medical and health facilities,and the spatial distribution is characterized by a southward shift in the east and uneven regional distribution.Overall,the supply capacity of rural pension services was generally good,with the township center as the gathering point and spreading out in a faceted manner,with nearby townships forming a contiguous area;however,there were strong contrasts and obvious differences in the strength of supply capacity.However,the spatial equity of rural eldercare service was poor.In 42.05%of the eld-erly population grid cells,eldercare service spatial equity was extremely low.The spatial distribution also presented a northern preference over the southern,a western preference over the eastern,and a concentration along the highway.The study explored the realization of spatial equity in the optimal allocation of rural elderly services based on paying attention to the refined needs of the rural elderly pop-ulation,a vulnerable group,to provide a reference for solving the shortcomings of basic public services in rural areas.The fair allocation of rural elderly services demands that the spatial optimization of facility layout be organically coordinated with policy,management,and post-maintenance,and all elements in the rural territorial system be fully mobilized to achieve the basic guarantee of China’s rural elderly problems.

Exploring the growth value equity valuation model with data visualization

The Growth Value Model(GVM)proposed theoretical closed form formulas consist-ing of Return on Equity(ROE)and the Price-to-Book value ratio(P/B)for fair stock prices and expected rates of return.Although regression analysis can be employed to verify these theoretical closed form formulas,they cannot be explored by classical quintile or decile sorting approaches with intuition due to the essence of multi-factors and dynamical processes.This article uses visualization techniques to help intuitively explore GVM.The discerning findings and contributions of this paper is that we put forward the concept of the smart frontier,which can be regarded as the reasonable lower limit of P/B at a specific ROE by exploring fair P/B with ROE-P/B 2D dynamical process visualization.The coefficients in the formula can be determined by the quantile regression analysis with market data.The moving paths of the ROE and P/B in the cur-rent quarter and the subsequent quarters show that the portfolios at the lower right of the curve approaches this curve and stagnates here after the portfolios are formed.Furthermore,exploring expected rates of return with ROE-P/B-Return 3D dynamical process visualization,the results show that the data outside of the lower right edge of the“smart frontier”has positive quarterly return rates not only in the t+1 quarter but also in the t+2 quarter.The farther away the data in the t quarter is from the“smart frontier”,the larger the return rates in the t+1 and t+2 quarter.

年报监管问询影响公司权益资本成本吗?——基于完善金融监管的视角

基于2015—2020年A股上市公司数据,从公司权益资本成本的角度考察了中国监管问询机制带来的经济后果。研究结果表明,与未收到年报问询函的公司相比,收到年报问询函的公司在收函后面临更高的权益资本成本。在此基础上,采用中介效应检验证实了投资者信心是年报监管问询影响权益资本成本的一条有效路径。进一步分析发现,分析师不倾向于跟踪预测被出具问询函的企业,但收到重组类函件的企业在收函后权益资本成本反而更低。作为事后监管的一种重要手段,证券交易所问询函形式并未因其“非处罚性”而丧失效力,其不但有助于投资者及时调整投资决策,同时也有助于警示上市公司主动规范其信息披露行为。

碳减排“时-空-效-益”统筹理论:Ⅱ.空间统筹

《联合国气候变化框架公约》(UNFCCC)倡导缔约方承担“共同但有区别”的减排责任,指出“各缔约方应当在公平的基础上,根据它们共同但有区别的责任和各自的能力,为人类当代和后代的利益保护气候系统。”《联合国气候变化框架公约》体现出应对气候变化两个维度的公平性,即区域公平性和代际公平性。其中,区域公平性一般指国家之间应对气候变化的责任分担问题(如各国的减排目标设定、排放配额分配等)。作为碳减排“时-空-效-益”统筹理论系列论文的组成部分,围绕气候治理中区域公平性与主体间博弈问题,构建了空间统筹方法,应用于全球和国家层面最优减排路径研究,科学回答了各区域主体减排责任分担及局部与整体减排协同关系问题,为统筹局部减排与整体减排提供方法基础。

教育公平视野下普职分流的思考与启示

认同普职分流的观点主张普职分流有助于学生就业,有利于教育公平,有助于提升教育教学效率。反对普职分流的观点认为职业教育的专业对应的是社会底层的职业,依照才能选拔并不公平,不利于职教学生的发展。在目前的发展阶段,普职分流只是影响职业分层和教育公平的因素之一,它还受到社会、家庭、认知等诸多因素的影响。在推动现代教育体制高质量发展的背景下,需要通过实行普通教育与职业教育的错位发展,完善普职平等的教育制度,优化按劳分配的薪酬体系等措施,确保实现普职协调发展。

实现共同富裕的一个路径探索:人力资本的增长与平衡效应检验

共同富裕是我国新发展阶段的一个远景目标,“富裕”和“共享”是实现共同富裕的关键。构造一个反映人力资本与城乡居民收入差距关系的理论模型,并基于经验证据检验人力资本通过增长效应和平衡效应推动“富裕”和“共享”,进而促进共同富裕的作用。研究发现,人力资本提升既有利于“蛋糕”做大,又能有效促进“蛋糕”更好地分配,显著提升了城乡居民可支配收入水平,且对农村居民收入的提升力度大于城镇居民,成为缩小城乡居民收入差距的关键变量,推动了“富裕”和“共享”目标的实现;中介效应检验证实了人力资本通过促进农村高技能劳动力流向城镇,间接推动城乡居民收入增长和差距缩小,从而实现其增长与平衡效应;分样本回归结果显示,人力资本的平衡效应在低收入省份更加明显,而在高收入省份不显著。

股权激励对国企创新投入的影响研究——基于混合所有制改革背景

选取2014—2019年沪深混改国企为研究样本,实证检验高管和核心技术及业务人员股权激励与企业创新投入的关系。结果表明:非国有股权制衡在影响高管股权激励促进创新投入的作用上表现为双重调节效应,在地方国企中更为明显。高管政治晋升激励对高管股权激励与创新投入关系的影响因国企层级而不同,在地方混改国企表现为正向调节效应,在混改央企表现为负向调节效应。研究结论为高管股权激励通过公司治理渠道影响企业创新提供了证据。

共同富裕背景下基本医疗保险的受益公平性研究——基于CHARLS数据的实证分析

基于“中国健康与养老追踪调查”(CHARLS)2011—2018年四期数据,研究两类基本医疗保险参保者的城乡身份、所在地区与收入水平对基本医疗保险受益的影响及其公平性,发现城镇职工医疗保险的覆盖率较低,而城乡居民医疗保险的实际覆盖率超过政策覆盖率;城镇和东部地区、高收入参保者的受益水平较高;医疗自付费用对低收入人群形成较大负担;随着时间的推移,参保者在不同维度的受益水平和公平性有所改善。模型分析结果还表明,在城镇职工医保内部,地区差距显著,东部、中部、西部、东北地区的住院费用水平依次递减,西部地区参保人员的健康水平显著低于东部地区;在城乡居民医保内部,城镇居民的受益水平显著高于农村居民和进城农民,东部地区居民的健康水平最高,而西部地区最低;参保者收入越低则住院费用越少,健康水平也越差。上述发现与结论对于进一步缩小不同城乡、地区和收入身份特征的参保者的受益差距,促进社会公平公正,推动共同富裕,具有一定的政策启示。

基于地理信息技术的山地城市社区体育文化公园空间分布分析——以重庆市为例

社区体育文化公园作为居民身心健康发展的重要场域,研究其空间分布及影响因素具有重要意义。文章以具有典型山地城市特征的重庆市为例,运用核密度估算法、最小阻抗法、空间插值法和地理探测器对重庆92个社区体育文化公园进行深入分析。研究发现:重庆市社区体育文化公园主要分布在渝中、渝北、南岸、巴南西部临江一带,总体分布与城市发展具有耦合性,其空间分布主要受交通可达性、房价、人口密度和地势等因素影响,其中交通可达性和房价影响较大,人口密度和地势次之。文章提出以区域发展水平为着力点,建设多层级社区体育文化公园;秉持“以人为本”的核心理念,建设“亲民”社区体育文化公园;以山地城市独有的城市形态,丰富社区体育文化公园内部空间结构等优化配置建议,为社区体育文化公园的规划提供重要参考。

公平而高质量的中考分流:价值向度、实践样态及路径选择

追求公平而高质量的中考分流,应坚持按教育“内适”规律、“外适”规律和“个适”规律办好人民满意的教育,用合适的高质量教育塑造合适的人,让不同的学生流向不同的高质量学校,使每个独特的天性都得到自由生长。由于各地执行标准不一及“双减”政策落实情况参差不齐,中考分流的适应性不强,成为普通高中与中等职业学校分化、中产以上家庭子女与中产以下家庭子女学业分化学业分化、优生与差生分化的“催化剂”,成为不同受教育者机会不均、地位悬殊、能力分化的“助燃剂”,成为天性教育的梗阻。坚持教育分流政策,实现公平而高质量的中考分流,必须因情、因地、因人制宜,建立普职平等的发展机制、需求导向的调节机制和减负增效的评价机制。

中国粮食种植业碳效应时空演化及碳排放公平性

农业低碳转型背景下,准确把握粮食种植业碳效应时空演化及碳排放公平性特征对实现地区生态正义具有重要意义。基于2000—2021年省域面板数据,采用碳排放因子法测算中国30个省区的粮食种植业碳效应,利用核密度估计方法探析时空演化,运用Dagum基尼系数法刻画并解构全国粮食种植业碳排放公平性。研究表明:(1)从时空特征看,粮食种植业碳效应呈现波动上升的净碳汇特征,具体表现为“东强西弱,北高南低”的空间格局,且伴随明显的“马太效应”。在碳效应结构上,秸秆燃烧与玉米种植分别是粮食种植业最主要的碳源与碳汇。(2)从演化趋势来看,全国粮食种植业碳效应的非均衡性呈扩大趋势;在三大主粮中,水稻碳效应非均衡性有所减弱,小麦与玉米碳效应非均衡性均持续上升。(3)从碳排放公平性来看,区域间碳排放差异已成为影响公平性的最主要因素,基尼系数呈“快速上升-波动震荡-缓慢回落”特征,全国粮食种植业碳排放始终处于较公平区间,整体公平性呈改善态势;在三大主粮中,水稻碳排放公平性最低,玉米碳排放公平性最高。最后,提出了采取差异化固碳减排策略、构建低碳发展跨区协作机制、完善碳排放责任分摊机制、探索粮食碳汇交易试点等建议,以期推动我国粮食种植业实现低碳转型发展。
