Effects of financial development and capital accumulation on labor productivity in sub‑Saharan Africa:new insight from cross sectional autoregressive lag approach

This study aims to shed light on the effects of financial development and accumula-tion of capital on the productivity of labor in the sub-Sahara African region within the period of 1990–2018.In this work,we used the(dynamic)common correlated effects estimator-mean group and additional techniques such as cross-section autoregressive distributed lag to calibrate the sample into the African subregion to ensure robustness.The findings reveal that financial progress in the region over time leads to an increase in productivity of labor and also the accumulation of capital.Furthermore,financial markets have a progressive impact on the productivity of labor within sub-Saharan African regions.We extend the very limited literature on the nexus between financial development and labor productivity by incorporating capital accumulation into our model which has not been previously studied.

Agricultural Land Use Responses to the Rising Labor Opportunity Cost in Sui County,China

Rising labor opportunity cost is one of the most important characteristics of farmers' economic environment in present China,and brings great agricultural land use changes correspondingly.Based on the stratified random sample of rural households in Sui County,this paper estimates the opportunity cost of farm labors,and then analyzes its effect on farmers' agricultural land use decisions.The findings show that the households with higher labor opportunity cost are more likely to reduce labor intensity and increase labor-saving input in their land use decisions.From the descriptive analysis,we also find these households always prefer grain crop planting,reduce yield-raising input or even rent out their cultivated land.As labor and yield-raising input are two essential positive factors for grain production,continuous declining of labor input and yield-raising input caused by rising labor opportunity cost may influence the grain yield per unit area in the future.

Research on Human Capital and Higher Education Based on the Perspective of Employment of College Students

The status of human capital should match economic development. Researching the unemployment of college students firstly needs to know about the economic development stage and economic structure in China. Employment of college students not only is the problem of unbalanced supply and demand of college students, but also has close relationship with supply-demand relationship of higher education market. Employment of college students has relationship with two markets, education market and labor market, in which higher education supply is middle. For two markets, the decision-making subject make the optimal decision according to the principle that marginal income is equal to marginal cost. Under the specific economic development stage and economic structure in China, the family has greater requirement on higher education in education market, and the supply of higher education is insufficient. For labor market, economic development is difficult to fully absorb the existing college graduates, and the supply of higher education is excess. The imbalance of two markets causes the increase of supply pressure of higher education and idle human resource.

Spatio-Temporal Impact of Rural Livelihood Capital on Labor Migra- tion in Panxi, Southwestern Mountainous Region of China

Labor migration to urban centers is a common phenomenon in the Panxi region of the southwestern mountainous region of China, mainly owing to inadequate livelihood capital in rural areas. Numerous studies have been conducted to explore the relationship between labor migration and its causes, such as individual and family characteristics, but few studies have focused on livelihood capital. This paper examines the impact factors on labor migration employment location selection and duration from a household livelihood capital perspective. A case study of 279 households from 10 villages in the area was carried out in February 2016. We used both qualitative and quantitative methods to analyze the data. On the basis of the 279 questionnaires, the proportion of households with non-labor migration is 48.4%, whereas households with labor migration within a local city and migration across regions account for 28.7% and 22.9%, respectively. Social, financial, and human capitals are the primary factors that influence migrants' employment location choice positively. Among them, social capital has a significant impact on both migration within a local city and across regions; each of the regression coefficients is 1.111 and 1.183. Social, human, and financial capitals also have a positive impact on the duration of labor migration, and similarly, social capital is the highest coefficient with 2.489. However, physical capital only partly impacts labor migration across regions, whereas the impact of labor migration within a local city, and the duration, are not significant. Furthermore, the impact of household natural capital on migration space and time are all negative relationships, especially for labor migration across the regions and duration, with coefficient scores of 4.836 and 3.450, respectively. That is to say, a laborer is inclined to migrate within a local city for a short term, or not migrate at all, if natural capital is abundant. Our analysis results show that household livelihood capital has a strong spatio-temporal impact on labor migration.

Consolidating Contestation and Conflict through Community-Based Adaptation (CBA)

This article, based on fieldwork in Ghana, Burkina Faso and Kenya, provides an overview of different types of climate change adaptation interventions that are currently being implemented to enhance local community’s adaptive capacity and resilience. We show that CBA interventions, whilst measurably successful from the interventionist perspective, are often structured to cause new scarcities, competing claims and ultimately, various forms and intensities of conflict. We conclude that, instead of targeting “communities” or other groups of “beneficiaries”, the inter-connectedness of multiple (and at times competing) social groups (men and women, the elderly and youth, hunters, loggers, pastoralists and sedentary crop farmers etc.) in relation to the use and distribution of natural resources should be the point of departure for strengthening resilience and adaptive capacity.

Social Capital Approach for Explaining Ethnic Conflicts Within a Liberal Society

This paper examines the reasons why many ethnic movements surge in liberal societies-even though these societies are supposed to enable the coexistence of different types of people-and whether it is possible to resolve ethnic conflicts within these societies. Social capital, such as mutual trust, diffusion of information, and social support is used in this discussion, as successful coexistence in a liberal society is only possible when social capital is adequately provided to all people. Since social capital is generated from social networks, minorities want networks that may increase the likelihood that they will attain an adequate level of social capital. They attempt to build such networks by making their cultural symbols recognized by others. Confrontations that result from this kind of movement often cause ethnic conflicts. The key to resolution, then, is whether a broad network can be built, to which all different people are satisfactorily connected. As a result, this paper shows that even though such a resolution is theoretically possible, in reality there are three serious obstacles： （1） people tend to be driven by strong emotions; （2） people cannot accurately estimate the extent of suffering and/or the level of required support; and （3） minorities＇ primary networks are too solidified to be connected suitably to the wider network. These findings will contribute to the further argument of what conditions should be met in order to take feasible measures to resolve ethnic conflicts within a liberal society.

The Cause Analysis of College Student Human Capital Depreciation in China

Human capital depreciation can be divided into stock depreciation and utility depreciation, which will cause the waste of human capital investment, and let human capital value fail to fully embody, affecting social development. In the critical time of China facing population aging and economic transformation, as the new human capital of the labor market, college students play an important role to social and economic development. Therefore, preventing and mitigating their human capital depreciation is necessary. This article focus on human capital investment and configuration stage, analyze the influence of unreasonable human capital investment system and separate labor market segmentation system to college student human capital depreciation, and put forword the corresponding countermeasures.

从劳资对立到相互成就:对抗性劳动法制的反思和变革

西方资本主义国家的劳动法制以“劳资对立”为基础和逻辑,背景是大机器生产时代阶级对立的雇佣关系和中重度体力劳动,我国现行劳动法制在一定程度上受其影响。社会主义不存在劳动者和企业之间关系的根本性矛盾,而且公有制在我国占主导地位,劳动者远超“劳工”范围;普遍的脑力劳动和轻微体力劳动,高度市场化和科技进步条件下的灵活生产、工作,冲击着僵化的劳动法制;随着社会进步,越来越多的人出于兴趣志向和事业追求而工作;中国共产党的领导,确保中国不存在也不允许出现既得“利益集团”。故应当在此新的历史条件和国情基础上,构建一种劳动者和企业相互成就的和谐劳动关系与包容、柔性的社会主义劳动法制,一体适用于各种经营性的雇佣及劳动合作,劳动事故和失业等风险概由社会保险暨社会承担以解决个别企业经营及市场竞争的后顾之忧。

社会信用与企业韧性——基于社会信用体系改革试点的准自然实验

在当前全球经济环境不稳定的背景下,如何增强企业韧性是所有企业都要面临的重要问题。文章基于2007—2021年我国A股上市公司的平衡面板数据,测度了企业韧性水平,并以城市社会信用体系改革试点作为一项准自然实验,运用多时点DID模型实证检验了社会信用对企业韧性的影响。结果表明:社会信用提升能够显著增强企业韧性;社会信用主要通过提高城市人力资本水平、降低企业交易成本和提升企业劳动生产率三个机制来增强企业韧性。异质性分析发现:社会信用对企业韧性的增强作用在内部治理水平较低企业、非国有企业、市场化程度较低地区中的效果更大。文章为研究企业韧性的影响因素提供了新的视角,对如何增强企业韧性、实现企业高质量发展具有一定的启示。

我国资本市场开放能否促进企业自主创新?——基于“沪深港通”交易制度的经验证据

自主创新能力提升是增强企业核心竞争力的关键因素,深入探究资本市场开放如何支持企业自主创新对于培育创新型经济发展至关重要。本文基于“沪深港通”交易制度的实施构造准自然实验,以识别资本市场开放对企业自主创新的影响。结果表明,我国资本市场开放通过优化投资者结构,降低企业风险承担,促使劳动力技能升级,最终助推企业自主创新能力提升。异质性分析表明,在融资约束较高、外部融资依赖程度较高、行业竞争度较高、全要素生产率较高、内部治理效率和外部监督水平较高的企业中,资本市场开放对其自主创新能力的助推效应更为凸显。“沪深港通”交易制度实施对标的企业周边非上市企业的自主创新及当地的创新创业活动均具有显著的正向溢出效应。本研究不仅为促进实体经济创新型发展提供新经验证据,也为完善金融支持创新体系提供重要的理论指导。

数字劳动主体困境的生成机理与规制路径

数字劳动是数字时代全新的劳动范式。在资本逻辑统摄下,数字生产被以数字技术为中介的资本增殖所控制,形成了一个以数据为核心要素、以程序算法为生产条件的新剥削系统。资本逻辑全面渗入劳动主体的生活领域,推动着资本主义剥削系统从“物化系统”转变为“物性秩序”。在这一秩序内,数字劳动者被置于全时段和全领域的资本规训下,劳动者的主体性进一步丧失。数字技术强化了资本的社会权力属性,创造了数据这一新的生产要素,进一步剥夺了数字劳动者的自主性,数字劳动主体从“机器附庸”转变为“数字附庸”。破解数字劳动的主体困境,必须从社会主义制度入手,打破数字资本与数字技术之间以赚取最大利润为目的而加剧的劳动异化,规制数字资本的负面效应,将数字劳动创造的社会财富回归于人本质的占有。

刘易斯转折点、缴费负担转嫁与高龄农民工参加城镇职工基本养老保险趋势——理论推断与实际证据

高龄农民工特指户籍仍在农村、在本地从事非农产业或外出从业6个月及以上的50岁及以上劳动者。中国刘易斯转折点大概出现在2010—2014年。与人口结构尤其是年龄结构相对应的刘易斯转折点前后,高龄农民工参加城镇职工基本养老保险个人缴费负担和用人单位缴费负担转嫁内在地决定着高龄农民工参加城镇职工基本养老保险的比例及其变化趋势。刘易斯转折点之前高龄农民工参加城镇职工基本养老保险的比例偏低,刘易斯转折点之后高龄农民工参加城镇职工基本养老保险的比例会增加,实证检验证实了这一理论推断。为了提高高龄农民工未来的养老保障程度,提出以帕累托改进原则推进高龄农民工养老保障制度改革,督促高龄农民工与用人单位签订劳动合同,做好高龄农民工基本养老保险关系转移接续,实施多样化的高龄农民工养老保障方式。

工作−家庭冲突与中小学教师工作繁荣的关系:基于多项式回归与响应面分析的探索

使用问卷法对2876名中小学教师进行调查,探讨工作−家庭冲突的双向对比情况与中小学教师工作繁荣的关系,以及心理资本在二者关系中的作用机制。结果发现:(1)当工作干扰家庭与家庭干扰工作水平一致时,与“低−低”干扰相比,“高−高”干扰的教师具有更低的工作繁荣水平和心理资本水平;(2)当工作干扰家庭与家庭干扰工作水平不一致时,与“高−低”干扰相比,“低−高”干扰的教师具有更低的工作繁荣水平和心理资本水平;(3)教师的心理资本在其工作−家庭冲突与工作繁荣的关系之间起部分中介作用。

劳动力流动赋能城乡融合:理论机制与实证检验——基于安徽省6县1002个农户的问卷调查

城乡融合在构建新型城乡关系中发挥着基础性作用,劳动力流动则为城乡融合目标的实现提供了新的可能。安徽省作为传统的农业大省及全国农村劳动力转移大省,城乡融合问题是制约其经济发展的重要因素。因此,基于微观调研数据,探究安徽省劳动力流动对城乡融合发展的影响,并通过机制分析检验资源配置和人力资本在劳动力流动赋能城乡融合过程中的间接作用。研究发现:劳动力流动显著促进了城乡融合发展,这一结论在经过一系列严谨检验后依然成立;劳动力流动可以通过优化资源配置、聚集人力资本等路径有效推动城乡融合;劳动力流动对城乡融合发展的促进效应存在明显的区域异质性,尤其在对政策相对不完善地区的城乡融合促进上,其效应更为显著。基于此,为进一步全面深化改革、促进城乡融合发展、推进中国式现代化建设,提出应统筹资源配置、促进城乡产业融合,激发人才活力、增强城乡一体意识,完善市场规则、健全按要素分配制度,深化土地改革、推进新型城镇化建设,增强政策导向、规范劳动力有序流动等建议。

低碳技术发展产业链风险评估

“双碳”目标下,低碳技术将迎来大规模发展,传统技术被加速替代,会对产业链相关行业原材料、资金、劳动力需求以及污染物排放等产生直接影响。因此,亟须提前评估低碳技术发展可能引发的关键要素失衡以及部分行业环境影响攀升风险,以避免威胁产业链安全,制约“双碳”目标实现。为此,选取未来有望大规模普及的电解水制氢、电化学储能、低碳发电技术、电弧炉炼钢技术及多通道燃煤等10类低碳技术作为研究对象,评估2024—2030年各项技术大规模普及对产业链相关行业原材料、资金、劳动力需求和污染物排放的综合影响,识别潜在风险。结果表明:钴、铜、镍、锂、锰等关键矿产资源对外依存度高且未来需求增长快,面临短缺风险相对更大;发展光伏发电技术对资金的需求最大;电化学储能技术普及引致的劳动力需求增长最快;关键低碳技术产业链上游的电气机械和器材制造业将面临严峻的资金和劳动力供给不足风险;煤炭采选业将面临一定的劳动力过剩风险;金属矿采选业将面临较大的环境污染上升风险。并进一步针对技术、组件、上中下游行业可能面临的风险提出了应对策略。

财产权的张力:洛克与马克思

洛克作为近代政治哲学财产权思想的开创者,在《政府论》中从自然权利论说出发,提出“劳动创造价值”的劳动所有权思想。马克思继承了洛克劳动所有权思想的核心,在劳动价值论的基础上发现剩余价值,揭露资本家对劳动者剩余价值的无偿占有,开启了财产权的资本逻辑批判。在《资本论》中,马克思发现资本主义财产权是以劳动所有权为外在形式,背后隐匿着否定自我所有的资本所有权,揭示了财产权的现代分离。马克思将洛克的劳动所有权发展为劳动力所有权,在重建个人所有制中实现人的自我所有,完成了对财产权的正义建构。
