本文根据两部门经济增长模型,以1995~2009年中国29个省际数据为对象,运用分位数回归的方法考察了人力资本、产业结构对中国经济增长的影响。理论分析和实证研究均表明:人力资本对经济增长有显著的促进作用,且在条件分布的不同位置,这种作用存在明显差异;产业结构从传统产业向现代产业的转化也是经济增长的重要推动力;人力资本的经济增长效应受产业结构的影响,与人力资本相适应的产业结构转化可以优化人力资本的配置,提高人力资本的产出效率,有助于经济持续、快速地增长。  相似文献

上山下乡运动类似于一场社会大实验,知青则是在这一特殊历史背景下产生的,本文从分位数回归视角对其人力资本回报进行了探究.数据表明,知青在工作中并不具有人力资本、工作特征等优势,但基准OLS估计表明,知青的教育回报率和工作经验回报率普遍高于非知青组.具体在不同分位数上,各分位数的教育回报率中非知青群体最高,知青次之,“老三届”知青组最低.两种结果的差异可能是由知青、“老三届”知青的教育回报率呈现“U形”趋势所导致的,即回报率随着分位数的提高先减小后增大.  相似文献

基于2000-2021年省级面板数据,采用面板分位数模型分析老龄化对城镇化的影响及其作用机理,发现在全国及东、西部地区,老龄化会抑制城镇化的发展,且其边际效应递减,而中部地区老龄化呈倒U型影响效应,相比东部地区,中部地区老龄化对城镇化的影响更深远,未来中西地区城镇化建设应重点进行就近城镇化。产业结构升级促进城镇化发展,而城乡收入差距扩大会阻碍城镇化进程,且边际效应都呈递增趋势。据此提出更加重视高城镇化地区构建完整社会保障体系,重点在中西部地区推进城乡一体化和就近城镇化,东部地区应大力发展银发经济等对策建议。  相似文献

采用普通线性回归方法来研究盈余稳健性,只能描述Basu模型中收益与盈余关系的平均程度,无法完整呈现两者之间的各种可能关系。文章基于分位回归方法,利用经过调整的Basu模型,试图发现我国上市公司不同盈余水平与稳健性之间的关联。结果发现,在盈余管理的影响之下,不同盈余水平上的企业盈余稳健性程度不一,处于分位值两端的公司稳健性高,处于中间分位值的企业稳健程度低。  相似文献

基于分位数回归方法,本文重点考察人力资本和贸易开放度对中国全要素生产率的影响.结果表明:[1]从全国范围看,人力资本对全要素生产率增长存在较弱的即期效应,而贸易开放度则表现为滞后效应;[2]这两个因素在各分位点处对全要素生产率增长的影响表现出鲜明的区域差异.只有在东部地区,人力资本对全要素生产率增长的影响才具有较强的即期效应,西部地区贸易开放度对全要素生产率的影响存在滞后性,且滞后期相对较长,而中部地区与全国整体表现较为相似.  相似文献

The solvency issue of life insurance companies has become more important in recent years as business risks turn increasingly greater. This study examines the relationship among investing risk, underwriting risk, and the capital ratio during the post risk-based capital regulation period of 2004–2009 in Taiwan. In addition to the two-stage least square regression (2SLS), we also adopt the two-stage quantile regression (2SQR) to capture the effects of low capital (or risk) levels and high capital (or risk) levels. 2SLS do not fully explain the capital-risk relation. Contrary to previous evidence reported in the U.S., our findings in 2SQR model indicate that the relationship between capital and underwriting risk is positive, while the relationship between investing risk and capital shows a reverse pattern. Overall, the 2SQR provides stronger evidence than the 2SLS.  相似文献

Under minimal assumptions, finite sample confidence bands for quantile regression models can be constructed. These confidence bands are based on the “conditional pivotal property” of estimating equations that quantile regression methods solve and provide valid finite sample inference for linear and nonlinear quantile models with endogenous or exogenous covariates. The confidence regions can be computed using Markov Chain Monte Carlo (MCMC) methods. We illustrate the finite sample procedure through two empirical examples: estimating a heterogeneous demand elasticity and estimating heterogeneous returns to schooling. We find pronounced differences between asymptotic and finite sample confidence regions in cases where the usual asymptotics are suspect.  相似文献

Green innovation is an effective path to decrease environmental pollutions. It is of immense interest to evaluate the roles of green innovation on SO2 emissions reduction. We also investigate the static and dynamic threshold effect of human capital in the impacting paths of different innovations on SO2 emissions. The empirical results show that the design patent increases SO2 emissions while the development of utility patent can decrease SO2 emissions based on the static analysis and dynamic analysis. Both the “pollution halo” and the “pollution heaven” hypotheses of foreign direct investment (FDI) are validated in China. Moreover, green innovation positively affects SO2 emission reduction based on the System Generalized Method of Moment (SYS-GMM) estimation. Both static and dynamic panel threshold regression results reveal that the positive effects of different innovations will become larger when human capital exceeds the corresponding threshold values. Hence, it is important to enhance green human capital.  相似文献

This paper estimates a class of models which satisfy a monotonicity condition on the conditional quantile function of the response variable. This class includes as a special case the monotonic transformation model with the error term satisfying a conditional quantile restriction, thus allowing for very general forms of conditional heteroscedasticity. A two-stage approach is adopted to estimate the relevant parameters. In the first stage the conditional quantile function is estimated nonparametrically by the local polynomial estimator discussed in Chaudhuri (Journal of Multivariate Analysis 39 (1991a) 246–269; Annals of Statistics 19 (1991b) 760–777) and Cavanagh (1996, Preprint). In the second stage, the monotonicity of the quantile function is exploited to estimate the parameters of interest by maximizing a rank-based objective function. The proposed estimator is shown to have desirable asymptotic properties and can then also be used for dimensionality reduction or to estimate the unknown structural function in the context of a transformation model.  相似文献

The paper discusses the asymptotic validity of posterior inference of pseudo‐Bayesian quantile regression methods with complete or censored data when an asymmetric Laplace likelihood is used. The asymmetric Laplace likelihood has a special place in the Bayesian quantile regression framework because the usual quantile regression estimator can be derived as the maximum likelihood estimator under such a model, and this working likelihood enables highly efficient Markov chain Monte Carlo algorithms for posterior sampling. However, it seems to be under‐recognised that the stationary distribution for the resulting posterior does not provide valid posterior inference directly. We demonstrate that a simple adjustment to the covariance matrix of the posterior chain leads to asymptotically valid posterior inference. Our simulation results confirm that the posterior inference, when appropriately adjusted, is an attractive alternative to other asymptotic approximations in quantile regression, especially in the presence of censored data.  相似文献

Sir Francis Galton introduced median regression and the use of the quantile function to describe distributions. Very early on the tradition moved to mean regression and the universal use of the Normal distribution, either as the natural ‘error’ distribution or as one forced by transformation. Though the introduction of ‘quantile regression’ refocused attention on the shape of the variability about the line, it uses nonparametric approaches and so ignores the actual distribution of the ‘error’ term. This paper seeks to show how Galton's approach enables the complete regression model, deterministic and stochastic elements, to be modelled, fitted and investigated. The emphasis is on the range of models that can be used for the stochastic element. It is noted that as the deterministic terms can be built up from components, so to, using quantile functions, can the stochastic element. The model may thus be treated in both modelling and fitting as a unity. Some evidence is presented to justify the use of a much wider range of distributional models than is usually considered and to emphasize their flexibility in extending regression models.  相似文献

Adrian, Boyarchenko and Giannone ((2019), ABG) adapt quantile regression (QR) methods to examine the relationship between US economic growth and financial conditions. We confirm their empirical findings, using their methodology and their pre-2016 sample. Mindful of the importance of the Covid-19 pandemic, we extend the sample to 2021Q3 and find attenuation of the key estimated coefficients using ABG's empirical methods. Given the pandemic observations, we provide robust QR analysis of dependence based on ranked data and explain the relationship with extant copula modelling methods.  相似文献

人力资本价值能否得到合理的补偿,不仅直接影响着人力资本价值的实现程度,而且影响着新一轮的人力资本运动,即新的人力资本的形成和使用。我国人力资本价值补偿机制尚不健全,人力资本价值与收入分配之间并未呈现一定的正相关关系。劳动者地位虚化与人力资本产权缺损,是我国人力资本补偿机制不健全的根源所在;相应地确立人力资本收益权,则是对人力资本价值进行合理补偿的根本途径;而人力资本股权化,又是确立人力资本收益权的具体体现。人力资本股权化的对象主要是企业中处于关键技术岗位和重要管理岗位的人力资本所有者。与此同时,还要重视完善人力资本产权保护体系。  相似文献
