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.

Is the feminization of labor harmful to agricultural production? The decision-making and production control perspective

Even today,academics continue to debate the effect of feminization of agricultural labor force on agricultural output.By considering the dimensions of participation in decision-making and production,this study divides the various agricultural production models into three types:(i)the traditional model of decisions made either jointly by men and women or by men alone while both genders participate in production,(ii)complete feminization of agricultural decision-making and the production labor force,and(iii)feminization of the agricultural production labor force only.This study investigates the effects of combining or separating decision-making and production in regard to agricultural development in the context of feminization of the agricultural labor force.Using follow-up data collected from 2004–2008 by the Ministry of Agriculture of China,we built a comprehensive panel data model to test our hypotheses.Our research shows that in comparison to traditional agricultural households and fully feminized agricultural labor forces,partially feminized production resulted in lower grain yield and technological advancement.The feminization of agricultural labor does not necessarily have a negative impact on agricultural output,especially since heavy manual labor is being increasingly replaced by agricultural machinery and outsourcing of tasks.The degree of feminization of the decision-making and production processes should be an important consideration when evaluating the purported negative effects of the feminization of agricultural labor.

The Growth Path of Agricultural Labor Productivity in Major Grain Producing Areas

The growth of agricultural labor productivity in major grain producing areas arises from the increase in production factors or improvement of efficiency,and is related to the sustainability of agricultural economic growth and national food security. We study the growth path of agricultural labor productivity in 13 major grain producing areas of China,and the analysis results show that from the relative endowments of land and labor in major grain producing areas,the growth rate of the output value per unit of labor is higher than that of the productivity per unit of land; in essence,this growth path of increasing the output value relying on increasing the production factor inputs is the reduction of labor,and the reduction of agricultural labor has a great elasticity of impact on the total value of agricultural production. In the case of stable future number of agricultural labor in China,the growth of agricultural labor productivity will be impossible to rely more on the increase in agricultural production factor inputs,and the growth path of agricultural economy still has to rely on the improvement of land productivity and take the efficiency-based path.

Empirical Study on the Impact of Rural Labor Force Flow on the Price of Agricultural Products——A Method Based on VEC Model

Based on the research introduction of domestic and foreign scholars,dynamic equilibrium between the rural labor force flow and the price of agricultural product is analyzed by VEC model,according to the data of the rural labor force flow and the price of agricultural products in the years 1990-2007.Chows breakpoint test is used to measure the stage characteristics of the impact of rural labor force flow on the price of agricultural product.Result shows that there is a long-term and stationary relationship between the flow quantity of rural labor force and the price of agricultural product.Rural labor force flow,as an exogenous force,affects the agricultural production,and further influences the price fluctuation of agricultural products.Impact of rural labor force flow on the price of agricultural product is from weak to strong,then grows gradually weaker,and reaches its peak value at the year 1998.With the development of rural society and economy and the market process,rural labor force flow endogenously affects the price of agricultural product,which has periodic characteristics.In order to achieve a dual stabilization of the rural labor force flow and the price of agricultural products,the following countermeasures are put forward:vigorously developing vocational education,increasing the support for agricultural production,and making active employment measures.

Relationship Between Social Economic Agglomeration and Labor Productivity of Core Cities in Northeast China

Dalian, Shenyang, Changchun and Harbin are the four core cities which play an essential role in terms of promoting the economic development in Northeast China. In this paper, the impact of urban agglomeration on labor productivity is explored by making comparisons among these four cities. The model used for analysis is a classical model derived from previous studies. Some indicators, such as population density and economic density, were selected to examine the impact of urban agglomeration on the labor productivity based on the time-series data for the four cities from 1990 to 2007. The four main conclusions are: 1) The promotion from the growth rate of population density on the growth rate of labor productivity is limited. 2) The negative relationship exists between the growth rate of employment density and the growth rate of labor productivity. 3) Agglomeration effect exists in the four cities, the highest one is Dalian, Shenyang takes the second place, followed by Changchun and Harbin, and the predominant promotion exerted on the labor productivity is the output density.

The Estimation Methods for Agricultural Surplus Labor Based on Stochastic Frontier Production Function

The existing calculation methods for the number of agricultural surplus labor have a common flaw,that is,they can not reflect the impact of technical efficiency changes in agricultural production on the surplus labor. Based on the basic principle of stochastic frontier production function,this paper calculates the agricultural production technical efficiency of various provinces,and selects the province with the highest technical efficiency to assume that its agricultural labor is fully utilized,and there is no agricultural surplus labor. With the ratio of agricultural labor number to agricultural output value in this province as a reference,this paper calculates the number of agricultural surplus labor in other provinces. This calculation method makes up for the shortcomings of the existing calculation methods; it reflects the relationship between the number of agricultural surplus labor and production technical efficiency.

Labor Productivity Growth Effect of Industrial Structure Evolution in Guangdong Province during the Period 1978-2008:An Empirical Test of “Structural Bonus Hypothesis”

The labor flow promotes the industrial structure evolution,thereby affecting the growth of productivity.In the western industrialized countries,improvement in labor productivity has become an important source of economic growth.On the basis of analyzing changes of the industrial structure,changes of the structure of labor factor,changes of labor productivity and the growth rate in Guangdong Province in different periods,we use shift-share method to analyze the labor productivity effect of industrial structure in Guangdong Province,and put forward the following recommendations for the adjustment of industrial structure in Guangdong Province:(i) The adjustment of industrial structure should promote the reasonable and effective flow of labor between industries;(ii) Accelerating the optimization of the industrial structure is conducive to economic growth and improvement in labor productivity;(iii) In addition to structural optimization,the improvement in labor productivity should also focus on the improvement in intra-industry technology.

Labor compensation,labor productivity and labor cost advantage—An empirical study of Chinese manufacturing enterprises during 2000-2007

Unlike the usual practice of equating wages or labor compensation with labor cost,this paper incorporates labor productivity into an analytical framework and holds that the labor cost advantage is the relative relationship between labor compensation and labor productivity.Based on an empirical study of the data of Chinese manufacturing firms that include all state-owned enterprises and non-state-owned enterprises with their annual revenue greater than 5 million yuan from 2000 to 2007,this paper finds that labor compensation growth was accompanied by faster labor productivity growth.Hence,the labor cost advantage was not weakened during this period.Furthermore,this paper conducts an exploration of how to sustain labor cost advantages in the future and proposes that they can be sustained by upgrading the industrial structure and improving the education system.

Regression Analysis of the Sensitivity of Labor Productivity in Tourism to Operating Costs

The paper investigates the impact of selected variables of operating costs on labor productivity in the activity of accommodation and preparation and serving of food and beverages in the period from 2010 to 2020.The research was conducted by applying more linear on a sample of all companies that submitted annual financial reports in the observed period.The authors elaborate the special characteristics of the importance of labor productivity as an important indicator of business success,methods,and importance of business cost management and analyze the sensitivity of labor productivity to the costs incurred.Based on regression analysis,it is concluded that the amount of costs has an impact on the growth or decline of labor productivity,but based on the results of some of the costs incurred in business positively affects labor productivity,which is partially confirmed by the hypothesis of this study.

Integrated Development of China's Agricultural Labor Market from the Perspective of Convergence of Planting Industry Marginal Labor Productivity

Using Compilation of National Cost Benefit Data of Agricultural Products in 1990-2009 and based on the convergence of planting industry marginal labor productivity,this paper studies the integration of agricultural labor market in China. Firstly,it calculates labor output elasticity of each province for wheat,japonica rice and corn. Secondly,it builds indicators reflecting change level of marginal labor productivity. Researches show that in 1990-2000,the difference level of marginal labor productivity expands. From 2000,it starts to fall and becomes more and more stable. However,due to difference of crops and farming custom,the turning point of marginal labor productivity is not consistent with each other. Even so,it is still possible to reach the conclusion that agricultural labor market is gradually integrated from 2000.

A Comparative Study on the Labor Productivity of Provincial Textile Industry Based on DEA in China

Making use of the DEA-based method of quadruplicate decomposition of labor productivity, the paper analyzes the influence of labor productivity of provincial textile industry in China, caused by the effect of technical efficiency, pure technical progress, changes of scale efficiency of capital per labor and of capital intensity from the year of 2002 to 2005. Its results show that the improvement of provincial textile industry labor productivity has mainly resulted from technical progress since 2003. Meanwhile, labor productivity of underdeveloped provinces has been growing faster than that of developed ones owing to technology diffusion. And then, the above-mentioned improvement has originated from the enhancement of capital deepening and technology efficiency. In addition, scale return of capital per labor appeared to decrease during the period from 2004 to 2005.

Changes of the Scale and Structure of Agricultural Laborer and Their Impacts on Food Production——Empirical study on YinshanPo Village, Suizhou City

On the strength of expounding the general situation of study area and the status quo of agricultural laborers in China, the changes of the scale and structure of agricultural laborer from 1985 to 2009 are analyzed by relying on the survey from farmers and statistical data from the government. The causes of these changes are analyzed from the aspects of rural farmland policy,birth-control policy, farmland marginalization and industrialization. Based on the study on the causes, the impacts of the changes on food production are analyzed from operation scale of household, the grain cropping area, the multi-cropping index and land productivity. The results show that the quality of agricultural laborers is decreasing form 1985 to 2009, which is characterized by the lack of middle-aged agricultural laborers and the aging of agricultural laborers. The causes of the changes include farmland policy, birth-control policy, farmland marginalization and urbanization. The shrinkage of agricultural laborers has grave impact on the multiple-cropping index. In addition, the land productivity is comprehensively affected by the scale and structure of agricultural laborers.

Differing Effects of Intra-Product International Division of Labor on Technological Progress:Comparing Proactive Participation with Passive Inclusion

This paper has identified two models of intra-product international division of labor:the model of passive inclusion and the model of proactive participation.Their difference is essentially whether participation in international division of labor is dominated by multinational firms or by local firms.At the level of representative sectors,some characteristic variables of participation in international division of labor demonstrate significant industry differences.Models of division of labor affect technology progress.According to the empirical analysis result at the micro-level of four sectors,no matter for export or the contribution of learning by doing to corporate technology progress,the model of proactive participation is superior to the model of passive inclusion;under the model of passive inclusion,the technology spillover effect of import is smaller than "learning by doing " effect;under the model of proactive participation,technology spillover effect is over two times the "learning by doing" effect.

企业数字化转型对劳动收入份额的影响

数字化转型作为企业未来发展的新动能,其是否能够提高企业劳动收入份额,优化内部收入分配格局仍存在争议。为厘清二者之间的作用关系,需要在从理论上廓清数字化转型影响企业劳动收入份额的经济逻辑的基础上,利用2012—2020年中国沪深A股上市公司数据进行实证检验。研究发现:数字化转型从整体上提升了企业劳动收入份额,实现了“分好蛋糕”的目标;数字化转型通过工资率和劳动生产率影响劳动收入份额,且对工资率的影响大于对劳动生产率的影响,从而产生数字化转型提高企业劳动收入份额的净效应;数字化转型能够提高企业增加值,实现“做大蛋糕”的目标;与劳动密集型企业相比,资本技术密集型企业的数字化转型对劳动收入份额的提升作用更大;与非国有上市公司相比,国有上市公司的数字化转型对劳动收入份额的影响程度有所下降,主要原因在于国有企业对社会责任的特殊承担。通过揭示数字化转型影响劳动收入份额的内在机理,可以为二者之间作用关系的争议提供微观层面的实证依据,也为数字经济背景下企业如何兼顾效率与公平,实现共同富裕提供有益的政策启示。

劳动生产率异质性如何影响劳动者退休时间决策?

基于人口老化与财务平衡推定提高退休年龄是劳动生产率同质假设的静态逻辑。理论上,最优退休时间取决于劳动者退休后消费水平与休闲收益的权衡。劳动生产率是能够同时影响消费水平与休闲收益的本质性变量,对劳动者退休时间决策具有双重效应。劳动生产率异质性使不同劳动者、不同时期的退休时间决策具有明显的异质特征;国家与社会有必要对异质性劳动生产率导致的异质性的劳动者最优退休时间作出回应,从而适时优化现行退休时间政策。模拟分析表明,劳动生产率异质性决定了最优退休时间的异质特征,两者之间存在显著的反向关系;在基准情境下我国劳动者的最优退休时间约为63.16岁;若要维持60岁的法定退休年龄,则必须保持9%的劳动生产率增长率。因此,摒弃劳动生产率同质假设并重视通过劳动生产率路径缓解养老金压力、实施激励相容的弹性退休计划、不断提高劳动者与社会的劳动生产率等有助于改进我国退休政策的有效性和可持续性。

劳动力老化如何影响劳动生产率?——基于中国城市面板数据的分析

中国自2000年步入老龄化社会以来,人口老龄化程度持续加深,作为社会经济基本要素,劳动力老化使得社会经济发展面临一系列新挑战与新机遇。为探索劳动力老化对劳动生产率的影响机理,基于2000—2020年中国城市面板数据,在借鉴既往研究的基础上,利用长差分模型实证分析劳动力老化对劳动生产率的影响。研究发现,劳动力老化与劳动生产率之间呈负相关关系;进一步从要素投入和技术进步两个方面考察劳动力老化对劳动生产率的作用机制后发现,劳动力老化主要通过影响技术进步与劳动就业作用于劳动生产率;此外,劳动技能提升、公共财政投入等公共政策可以有效降低劳动力老化对劳动生产率的消极影响;最后,本研究认为,若想有效应对这一问题就要加强对生育问题的关注,要从劳动技能提升、公共财政投入等方面制定专门且有效的公共政策,并在具体实施时,注重相关政策向中西部地区、二线及以下城市等特定地区倾斜。上述这些研究结论有助于从劳动力老化视角解释中国城市劳动生产率的表现差异,对于推动人口发展新格局下的经济高质量发展具有重要意义。
