Early labor market outcomes of university graduates: Does time to degree matter?

Using university administrative and survey data drawn from the AlmaLaurea Consortium, we analyze the effect of time to degree on the early labor market performance of Italian graduates. The empirical strategy allows identifying separately the impact of elapsed time to degree on the transition from university to work and on earnings from other determinants specific to the academic path completed. Findings suggest that delayed graduation reduces the employment probability (0.8% points for each year of delay), and this effect is still persistent five years after graduation. Once employed, graduates not completing their degree within the minimum period are also penalized in their net monthly earnings, even five years after graduation. The most penalized groups are women and graduates in non-scientific fields.     

Workforce diversity and firm performance: Relational coordination as a mediator and structural empowerment and multisource feedback as moderators

Workforce composition in organizations has become increasingly diverse. As an important step in determining how workforce diversity leads to firm performance, we proposed relational coordination as a mediator through which diversity in age and education indirectly affects firm performance. We also highlighted two human resource management practices (structural empowerment and multisource feedback) as critical contingencies that moderate the effects of workforce diversity on relational coordination and firm performance. We conducted hierarchical multiple regression on multisource data (including responses from senior directors, department directors, managers, and employees, as well as financial performance) from 189 Korean firms in the manufacturing sector, which yielded support for our hypotheses. These findings offer novel theoretical and practical insights into the effective management of workforce diversity.     

贵州有色金属产业集聚度与竞争力的实证研究

促进有色金属产业集聚是提升贵州省有色金属产业竞争力的主要途径之一，因而准确测度和把握有色金属产业集聚与贵州有色金属产业竞争力的关系是非常必要的。文章把贵州省放在西部九省中进行对比分析，选取区位熵反映有色金属产业集聚度，选择企业数量区位熵反映矿产资源产业区域集聚度，选取产业产值区位熵反映有色金属产业经济集聚度，而有色金属产业竞争力则选取产值利润率借以反映。具体实证数据均来源于西部9个省份的2013统计年鉴与2013年的中国有色金属工业年鉴。通过实证研究认为贵州省有色金属产业存在诸如区域集聚、经济集聚不足，产值利润率低下，产业集聚效应难以充分发挥等问题。最后提出提升贵州省有色金属产业竞争力的相关政策建议。     

长江经济带土地出让与城镇化质量耦合协调研究

土地出让与城镇化质量作为城镇化的主要依托和核心追求,二者的关系影响到城市的可持续发展。以长江经济带为例,构建土地出让与城镇化质量综合评价指标体系,利用熵值法和耦合协调模型对二者耦合协调的时空差异做出实证研究,并利用ArcGIS将其空间显化。结果表明：研究期内长江经济带土地出让与城镇化质量的协调度呈现先增后减再增趋势；二者的协调度自西向东逐步增加,耦合度无明显分布规律,总体呈高水平耦合状态；土地出让与城镇化质量的协调度在城市群间的差异显著,但城市群内部的差异逐步减小。从土地出让与城镇化质量的耦合协调发展的视角,为实现城市健康可持续的发展提出政策建议。     

铁路集装箱运输与社会经济协同发展关系分析

针对我国铁路集装箱运输和社会经济发展的关系,选取了能够表征两者发展的时间序列变量,运用协同学理论,构建了铁路集装箱运输和社会经济发展关系的协同度量化模型,对近18年来两者的综合发展水平、协调度及协同度变化进行了分析。结果表明该模型能客观全面地评价铁路集装箱运输和社会经济耦合因素协同发展水平和状态,表明铁路集装箱运输发展和社会经济增长两者密切相关,二者在互动中循环发展。     

Who benefits from partial tax coordination?

In this paper, we investigate whether partial tax coordination is beneficial to countries within and outside a tax union, in which countries are supposed to compete in taxes and infrastructure. Our results demonstrate that a subgroup of countries agreeing on a common tax rate can harm both member and nonmember states. This is in contrast to the classical findings that partial tax harmonisation is Pareto improving. When a minimum tax rate is imposed within a tax union, we demonstrate that it does not necessarily improve the welfare of the member countries. Moreover, both the high‐tax and low‐tax countries can be worse off. This conclusion is at odds with the classical result that a high‐tax country benefits from the imposition of a lower tax bound.     

扬州市生态农业发展评价及预测研究

［目的］农业是国民经济的基础产业，发展生态农业是实现农业经济稳步增长的重要途径，也是我国发展现代农业的战略选择。对生态农业的现状进行评估，以期以此为依据为今后的发展提供可行性建议。［方法］文章研究从经济效益、社会效益和生态效益3个方面构建了包含14个指标在内的扬州市生态农业发展评价指标体系，并采用熵权法和加权法综合评定2011—2016年该市生态农业发展的经济效益、社会效益和生态效益及综合效益得分，在此基础上采用GM（1， 1）灰色模型对2018—2027年扬州市生态农业的发展程度进行了预测。［结果］2011—2016年扬州市生态农业发展的社会效益呈持续增长态势， 2011—2015年经济效益呈上升趋势， 2016年经济效益明显下降。生态效益分别在2012年和2016年出现两次波动。总体来看， 2012—2015年扬州市生态农业发展的综合效益逐年递增， 2016年由于经济效益的急剧降低，导致综合效益下降。2018—2027年该市生态农业的发展水平一直保持可持续状态，且发展度在逐年递增。［结论］扬州市在今后的发展过程中应注重转变生产方式，积极调整农业生产模式，努力实现农产品的集约化生产。注重环境保护，实现化肥农药使用量零增长，达到经济效益与社会效益和生态效益协调增长。     

国家审计与国家监察服务腐败治理的路径探索——基于协同视角的思考

随着国家监察体制改革的全面推进，国家监督系统焕发新的生机。国家审计与国家监察作为国家监督系统的重要组成部分，理应充分发挥监督职能以保证国家可持续发展。从国家监察体制改革特点入手，基于受托经济责任观，全面分析国家审计及国家监察分别与腐败治理的相关关系，并以腐败治理为核心，从战略层面、管理层面和结果层面三个层面探求国家审计与国家监察的耦合路径，使两者通过有效耦合路径将监督协同效应发挥到极致，进而保证政府公共受托经济责任全面有效地履行。     

自来水供应系统水质风险耦合致因分析

以城市自来水水质事故致因为研究视角,首先识别供水水质风险因素,并从单、双及多因素角度分析供水水质风险因素间的耦合关系,再借助N-K模型对2008—2017年全国所发生的362起城市重大供水水质风险耦合度进行度量。结果表明:城市自来水供应动态系统中,水质风险率随着参与耦合的风险因素的增多而增加;管理因素风险是水质风险的内因,风险管控是规避水质风险的关键;环境因素风险对水质事故的发生起推动作用。
