加强土地整理和易地开发，保持耕地总量动态平衡

土地是人类的母亲 ,耕地是人类的生命线。然而 ,我国耕地状况十分严峻。本文从土地整理和易地开发两方面探讨了保持耕地动态平衡的方法与对策。     

省际人力资本存量的估算——以江苏省为例

知识经济时代,人力资本对经济发展的作用越来越被人们重视,但对人力资本的如何度量的研究却相对薄弱,本文以江苏省为例,通过估算江苏省各级受教育程度人员总数、各级受教育程度人员的从业率,计算出各级受教育程度的从业人员数,再用受教育年限法估算出了江苏省人力资本存量,并对江苏省人力资本的发展状况和人力资本结构等进行了简要的分析。     

“危险驾驶”行为不宜独立设罪——对刑法修正案（八）第二十二条的评析

危险驾驶行为有巨大的社会危险性,刑法修正案（八）将飙车、醉酒驾驶等危险驾驶行为纳入刑法打击的范围,迎合了社会公众要求打击此类行为的舆论。但是,单独设立危险驾驶罪有悖刑法谦抑性,会造成刑法规范之间的不协调和实践操作上的困难。通过解释和完善现有刑法规范,完全可以满足对高危驾驶行为进行刑事处罚的需要。因此,在刑法中单设危险驾驶罪没有必要。     

农民环境权实现的多维度考量

部分农村地区环境持续恶化且不被重视是不争的事实,在改变农村地区环境现状、切实保护农民环境权这一问题上。应从文化传统、社会经济、法律制度、基层行政举措等多个维度进行综合考量才能找出行之有效的解决之道。

The Changing Pattern of Productive Efficiency in the Chinese Iron and Steel Industry

This study aims to explain the changing pattern of productive efficiency of the Chinese iron and steel industry during the 1980s. By decomposing productive inefficiency into technical, allocative and scale inefficiencies, the effect of market-oriented reform measures on inefficient resource utilization is empirically tested. A consistent improvement is found in technical efficiency from different sized firms. An improvement in allocative efficiency of investment in upgrading and innovation from different sized firms is also found. Allocative efficiency of working capital was found to have hardly improved which could be largely due to distorted factor markets. Different sized firms exhibited scale inefficiency which could be due to segmented local production and the impact of a two-tier price system on the distribution of production share among firms.

卖空限制与收益可预测性——A股融资融券制度的证据

基于A股市场融资和融券余额的巨大差距,本文拓展了Hong et al.(2016)的理论模型,在融券端和融资端分别找到了影响股票收益率的变量:融券比率(融券余额/流通市值)和融资回补天数(融资比率/日均换手率)。进一步,本文利用组合价差法和Fama-MacBeth横截面回归法,实证检验了A股市场中融券比率与融资回补天数解释和预测股票收益率的能力。实证结果表明,在存在融券限制条件下,融券比率相比融券回补天数(融券比率/日均换手率)能更好地代表套利者对股票价格高估程度的看法,根据融券比率构建的等权重多空组合能带来月均1.58%的显著收益;而由于融资约束相对较少,融资回补天数相比融资比率(融资余额/流通市值)能更好地代表套利者对股票价格低估程度的看法,根据融资回补天数构建的等权重多空组合能带来月均1.28%的显著收益。实证结果与本文存在融券数量限制下的理论模型相符,且该收益率不能被多因子模型和常规股票特征所解释。     

基于极大代数的高速列车运行延误模型研究

基于极大代数线性系统理论和运行图建立列车运行模型状态矩阵,分别研究建立列车顺序运行和区段列车或越行列车2种情况的列车运行系统。通过对线性系统输入矩阵或初始状态矩阵的参数设置,可以对任意列车在任意停站车站的发车时刻增加延误扰动,并基于所加扰动导致的延误列车本身及其他被影响列车的延误情况研究高速铁路列车运行延误模型。最后以某高速铁路实际列车运行情况建模,并通过仿真进行计算分析,验证模型的可行性。     

Evaluating green supply chain management among Chinese manufacturers from the ecological modernization perspective

Green supply chain management (GSCM) has become an emergent ecological modernization tool amongst Chinese manufacturers to balance environmental performance with productivity and business performance gains. Ecological modernization at the society level is influenced by restructuring policies and regulations. Some of these policies and regulations in China are focusing on enhancing energy savings and pollution reduction (ESPR). Based on a survey of 376 responses, we investigate whether different Chinese manufacturer clusters varying in their extent of implementing GSCM exist from this ecological modernization perspective. We also examine if Chinese manufacturers’ awareness of domestic and international environmental ESPR-oriented compliance is related to GSCM implementation and whether a mediating effect of regulatory pressure plays a significant role. The results highlight the varying pace of Chinese manufacturers to ecologically modernize with GSCM practices and the significance of regulatory pressure to diffuse the practices adoption by Chinese manufacturing industry. Implications of this research go beyond the manufacturers investigated in this study where similar occurrence of these relationships may exist in other regions.
