从市场经济体制的建立到经济社会高质量发展,我国不同部门市场化程度有所差异,劳动供给的部门异质性随之体现。基于中国劳动力动态调查数据,结合汉森门槛回归模型和劳动供给模型,依托部门市场化程度的差异性,文章探讨了工资对劳动力个人供给的非线性影响及其部门异质性。主要得出以下研究结论:第一,我国市场部门与公共部门劳动力的个人劳动供给有所差异。第二,工资与个人劳动供给呈现非线性关系并且存在部门异质性。实证分析结果显示,工资对个人劳动供给的影响存在三个"突变点",工资门槛均使得工资"激励效应"加强并呈现逐步增加的趋势。第三,劳动供给的工资门槛存在性别、城乡和行业异质性。第四,随着年龄增长、人力资本积累,个人劳动时间供给趋于降低,签署书面劳工合同使得市场部门劳动力工作时间显著增加,而政治面貌显著影响公共部门劳动供给。总体来看,无论是市场部门还是公共部门,我国劳动力个人供给曲线均未"向后弯曲",国民经济高质量发展、改善收入分配格局、提升居民幸福感等议题需持续关注。 相似文献

明代的香税以泰山和武当山的数量和影响为最。武当山香税的征收始于明孝宗弘治六年(1493年),是明代最早征收香税之地,由湖广布政司和提督太监委派的官员即均州千户所千户和太和宫提点负责。打着维修庙宇的旗号而征收的香税,在嘉靖以后还用于赈济灾荒,抵宗藩、官兵俸粮之不足等事项,正是明代中后期国家政治腐败、财政危机、加派风行的必然结果。 相似文献

The primary purpose of this paper was to empirically explore some of the reasons that logistics has become more important, or salient, in comparison to other functions within the firm. A survey of 296 managers across multiple industries in the U.S. found logistics becomes more important within the firm when the industry increases in uncertainty, when there is an emphasis on time‐based competition, when there is greater adoption of information technology, and when there is an emphasis on cross‐functional integration. 相似文献

Forecasting residential burglary 总被引:1,自引:0,他引:1
Following the work of Dhiri et al. [Modelling and predicting property crime trends. Home Office Research Study 198 (1999). London: HMSO] at the Home Office predicting recorded burglary and theft for England and Wales to the year 2001, econometric and time series models were constructed for predicting recorded residential burglary to the same date. A comparison between the Home Office econometric predictions and the less alarming econometric predictions made in this paper identified the differences as stemming from the particular set of variables used in the models. However, the Home Office and one of our econometric models adopted an error correction form which appeared to be the main reason why these models predicted increases in burglary. To identify the role of error correction in these models, time series models were built for the purpose of comparison, all of which predicted substantially lower numbers of residential burglaries. The years 1998–2001 appeared to offer an opportunity to test the utility of error correction models in the analysis of criminal behaviour. Subsequent to the forecasting exercise carried out in 1999, recorded outcomes have materialised, which point to the superiority of time series models compared to error correction models for the short-run forecasting of property crime. This result calls into question the concept of a long-run equilibrium relationship for crime. 相似文献

创新扩散理论按照用户采用新产品的时间先后顺序将市场细分为创新者、早期采用者、早期大多数、晚期大多数和落后者五种类型。本文在扩散经典理论和中国市场特征的基础上,提出城镇市场和农村市场耐用消费品用户构成差异的假设。研究结果证实了全部假设:城镇的创新者比例显著高于农村,农村的早期采用者比例显著超过城镇,而各类型采用者的采用持续时间农村全面长于城镇。这些结论为更加深入地了解二元经济结构下中国市场的特征提供了有益启示。 相似文献

房地产价格波动与投机行为--对中国14城市的实证研究 总被引:18,自引:0,他引:18
本文首先构建了适合中国的房地产投机理论模型,然后利用该模型对中国14个城市房地产价格波动与投机行为的关系进行实证研究.对14城市的时间序列数据研究结果表明各城市房地产投机水平都很高,个别城市更加突出.通过对14城市的截面数据分析,可以看出可支配收入对房地产价格没有显著影响,这些城市房地产价格的上升,主要是由投机来推动的,而且整体投机度非常高,说明房地产价格极大的偏离长期均衡值,市场出现了非理性繁荣,政府和产业部门应该采取适当的措施,积极引导消费者和投资者,为建立均衡的房地产市场提供良好的宏观和微观环境. 相似文献

There is currently substantial interest in valuing various services provided by different ecosystems. Concurrently economists have ascribed substantial effort on expanding traditional forest accounting systems by environmental services. This paper contributes to curtailing the existing gap between green accounting theory and applications for valuing forest ecosystem services. The multitude of links between forest ecosystem services and economy are characterized by the theoretical model for forest-economy interactions. By utilizing recently updated data we also incorporate empirical value estimates of these services comparable to other goods into Finnish forest accounting system. Finally, we discuss some problems encountered and clarify the interpretation of some value estimates incorporated to national forest account. 相似文献

股票市场收益率波动长记忆性的分解及实证研究 总被引:1,自引:0,他引:1
目前股票市场长记忆性检验和建模方法,不能很好地消除短期记忆的影响,针对这一问题,本文提出寻找序列的突变点,通过将序列分解为只包含长记忆性部分和不包含长记忆性部分的序列分解技术,来排除短期记忆的影响。对上证指数和深圳成分指数收益率波动的长记忆性进行实证研究发现,将序列分解以后进行长记忆性检验,不仅可以得出长记忆性检验更为精确的结论,同时可以检验序列分解过程的效果。 相似文献

Impatience and equilibrium indeterminacy 总被引:3,自引:0,他引:3
This paper extends the neoclassical one-sector optimal growth model by postulating that individual agents’ time preference (impatience) depends on the economy-wide average consumption and average income, which are social factors taken as external by individual agents. The paper shows that with the socially determined individual time preference local equilibrium indeterminacy can arise. Moreover, local indeterminacy can also be associated with global indeterminacy in many cases. The results hold in models with bounded and unbounded growth. 相似文献

Macroeconomic forecasting using structural factor analysis 总被引:1,自引:0,他引:1
The use of a small number of underlying factors to summarize the information from a much larger set of information variables is one of the new frontiers in forecasting. In prior work, the estimated factors have not usually had a structural interpretation and the factors have not been chosen on a theoretical basis. In this paper we propose several variants of a general structural factor forecasting model, and use these to forecast certain key macroeconomic variables. We make the choice of factors more structurally meaningful by estimating factors from subsets of information variables, where these variables can be assigned to subsets on the basis of economic theory. We compare the forecasting performance of the structural factor forecasting model with that of a univariate AR model, a standard VAR model, and some non-structural factor forecasting models. The results suggest that our structural factor forecasting model performs significantly better in forecasting real activity variables, especially at short horizons. 相似文献
