解放战争时期吉林省区域各类地方流通券 的货币设计研究

吉林省区域在解放战争时期流通的货币种类繁多,除了苏联红军票、中央银行东北九省流通券以外,还流通着一种可以统称为"地方流通券"的货币,它既包括了可以在东北全境流通的"东北银行地方流通券",也包括吉林省银行等区域性银行发行的"吉林省银行地方流通券""吉东银行券""吉江流通券""辽西流通券""辽东流通券"等货币.这些地方流通券设计中的制版、图案纹样、防伪理念等情况极具地方特色和时代特色,反映出当时解放区的生产生活状况和经济技术水平,也是解放前夕从分区发行货币到逐步统一货币的写照,更在一定程度上为人民币的设计与发展奠定了基础.

烟梗投料麻绳剔除装置的设计与应用

针对目前新疆卷烟厂制丝车间梗线生产HT梗时,采用麻袋封装,在梗条的运输过程中麻袋破损,导致梗条中混有麻绳,目前采用人工分拣,劳动强度大的问题,本文设计了一种烟梗中麻绳麻丝杂物装置,该装置由行星辊,耙钉,粘条,传动轴,行星辊,升降丝杠,机架等组成.装置制作完成后为了验证该装置的加装后的麻绳剔除效果,同时找到满足工艺要求条件下的最佳剔除效果,进行电机转速,工作时间和物料重量三因素三水平的正交试验.试验结果表明,该装置剔除效果最佳时的工作状态组合为:电机转速n为72r/min,工作时间t为2h,物料重量m为6000kg,继续优化验证试验,试验值与理论值相差小于5％,最佳结果满足烟梗中麻绳剔除分拣要求.

大规模MIMO系统中基于CNN的延迟CSI反馈改进算法

在大规模多输入多输出（Multiple-Input Multiple-Output，MIMO）系统中，基站根据用户反馈的信道状态信息进行自适应编码调制以提高频谱效率，因此需要将用户侧估计到的信道状态信息反馈到基站。由于反馈过程存在的延迟会降低系统性能，因此在考虑延迟的情况下，对基于深度学习的信道状态信息自编码器CsiNet进行改进，使用下行信道的延迟状态信息作为信道状态信息自编码器的期望输出信号来对自编码器进行训练，减少了反馈延迟误差的影响。仿真结果表明，在延迟为1时隙时，所提方案的归一化均方误差(Normalized Mean Square Error,NMSE)仅为自回归-主成分分析方案、基于压缩感知的方案和基于卷积神经网络的CsiNet方案的1/8~1/7，并且随着时隙增加，NMSE性能提升越明显。     

REGIONAL ANTI‐CORRUPTION EFFORT,POLITICAL CONNECTIONS AND FIRM INNOVATION EFFORT: EVIDENCE FROM CHINA

This paper examines how firm characteristics and local anti‐corruption effort moderate the influence of political connections on enterprises’ private R&D investment using data from 2,587 Chinese A‐share listed enterprises. Our results show that the local anti‐corruption institutional environment significantly moderates the strong relationship between political connections and enterprises’ private R&D investment. Firm characteristics (i.e., firm size and firm age) also show a moderating effect on the relationship between political connection and enterprises’ private R&D investment; larger and older enterprises are more likely to have innovative resources and business cooperation partners, and thus are able to reduce their degree of reliance on political connections and government funding. The results of our study suggest the importance of having a transparent and fair institutional environment for enterprise innovation activities.     

The Moderating Role of Strategic Integration in Performance Improvement Through Purchasing Social Responsibility in Thailand

This research aims to understand the performance of purchasing social responsibility (PSR) through moderating effect of purchasing strategic integration. The results show that PSR directly influences purchasing performance, while the relationship between PSR and purchasing performance is partially mediated by organizational learning. Moreover, strategic integration negatively moderates the relationship between PSR and purchasing performance. This study suggests that the adoption of PSR affects the operations of both buyers and suppliers in a supply chain that further encourage organizational learning and increases purchasing efficiency. The results also show that organizations may realize this effect of PSR practices but may focus on other purchasing practices, which affects purchasing performance. Copyright © 2018 ASAC.

城市家庭碳排放的地域特征与变动规律——以日本47个城市为研究对象

分析日本47个城市家庭碳排放的地域特征和变动规律,结果发现:(1)1991-2011年间日本家庭碳排放呈现周期性变化规律,并且随着时间的推移,清洁能源的碳排放在家庭碳排放中的比重逐渐提高;(2)城市家庭碳排放体现出明显的地域特征,随着纬度的提高,人均家庭碳排放逐渐增加,家庭碳排放在城市碳排放中所占比重也逐渐提高,由于城市面积和人口密度不同,单位可居住面积的家庭碳排放水平呈现出南北两侧城市较低、中间城市较高的特点;(3)城市人口、性别比、人均GDP、家庭年收入、家用汽车和城市平均气温均是城市家庭碳排放的重要影响因素,对不同家庭碳排放水平具有正向的驱动作用或负向的抑制作用。日本城市家庭碳排放的地域特征和变动规律,体现了城市化进入更高阶段的情况下,家庭各类能耗碳排放与相关影响因素的关系,这可以为我国在城市化水平进一步提高的过程中,分析城市家庭碳排放的变动趋势和控制对策提供指导和借鉴。     

Dynamics of firm's network community associations and firm's innovation performance

ABSTRACT

R&D network structures have crucial impacts on firm's innovation performance. However, most previous studies have been based on the whole or ego network perspective, few studies have investigated the influence of community structure that a firm is engaged in on its innovation performance, and it is still unclear how a firm's relation to network community affect its innovation performance. This research aims to address this gap by focusing on the dynamics of firm's network community associations, empirically investigate the relationship between dynamics of firm's network community associations and its innovation performance. Based on the unbalanced panel data of smartphone R&D network during year 2004–2017, the results demonstrate that change in community member associations and movement across communities both have inverted-U-shaped effects on firm's innovation performance. Moreover, innovation openness depth has moderating effects on the relationships between dynamics of firm's network community associations and its innovation performance.     

均衡性转移支付、公共支出结构与经济高质量发展

本文首先从理论层面系统阐述均衡性转移支付、公共支出结构与经济增长质量三者之间的多重作用机制。其次立足“五大发展理念”构建综合指标体系对经济增长质量展开测度，本文发现我国地方经济增长质量虽然在整体上呈缓慢上升态势，但其绝对水平相对偏低，且具有较为明显的地区异质性。最后本文通过构建动态面板联立方程模型与采取三阶段最小二乘法进行实证考察，结果表明：地方政府公共支出结构与经济增长质量显著正相关，但均衡性转移支付与经济增长质量的正相关关系并不显著。标准化回归结果显示均衡性转移支付能够通过优化公共支出结构对地方经济增长质量产生间接提升效应。
