DSBJ1200型伺服电子秤

由于当前包装计量秤在稳定性及精度上达不到生产所需要的要求,我们研制生产DSJB1200型伺服电子秤。本文论述了DSBJ1200型伺服电子秤的设备组成,主要技术参数,工作过程,主要性能特点和严谨的安全联锁系统。着重强调了DSBJ1200型伺服电子秤相比较传统包装计量秤的优点和改进。     

银行资本监管、资产价格与最优货币政策

本文构建一个包括银行资本监管、银行部门以及一个非有效资本市场的宏观经济模型,研究了银行资本监管、资产价格和最优货币政策之间的关系。结论表明,银行资本监管对最优货币政策的选择以及货币政策的资产价格效应均产生了显著影响。面对资本充足和资本不足两种银行体系,央行的最优货币政策对通胀和资产价格的反应程度明显不同。特别是当银行体系受资本监管约束时,最优货币政策对资产价格波动的反应比在资本充足情形下更加积极。     

人民币实际有效汇率变动对就业的影响——基于中国制造业企业层面的分析

汇率变动会影响到进出口产品（包括中间投入品）的价格,改变企业的出口竞争力和生产规模,进而影响企业对劳动力的需求,表现为就业创造和就业破坏两种效应。使用1998—2007年的微观企业面板数据和固定效应计量方法,并将实际有效汇率对就业的冲击分解为破坏效应和创造效应,分析人民币实际有效汇率变动对我国就业的溢出效应。结果表明,对于出口企业,实际有效汇率上升（人民币升值）的就业创造和就业破坏效应同时存在,且影响系数大致相当,其总体就业情况并没有受到实质性的影响;但人民币升值对我国制造业的整体劳动力需求会产生显著的负面冲击,加重就业压力。因此,当前人民币不宜大幅过快升值。

The Impact of Non-Labor Income Given Job Heterogeneity on Household Time Allocation: The Evidence from China

This paper proposes a theoretical framework based on new household economic theories. A dataset from the 2006 China Health and Nutrition Survey (CHNS) is used. Given heterogeneity in major family members’ jobs, the effect of non-labor income on household time allocation is discussed under two scenarios: jobs with flexible work hours and jobs with fixed work hours in the market. Based on the nature of the employer the major family member works for, employers can be categorized into four categories: government-owned, family contract, privately-owned, and foreign-funded. Each of the four categories is used for dissecting the data into different sets for analysis by category. The results imply that job heterogeneity is significantly correlated to household time allocation. An increase in non-labor income results in a decrease in the time allocated to housework for all households. However, leisure time is allocated differently among different households due to job heterogeneity. An increase in non-labor income leads to less leisure time for households working for government-owned or foreign-funded enterprises, and more leisure time for households working for family contract or privately-owned enterprises.     

Upgrading from OEM to OBM through Reverse Acquisition in China’s Emerging Economy: The Case of Lacquer Craft Mfg

In this paper, we review how original equipment manufacturing (OEM) firms break the “lock in the global value chains” (GVCs) and upgrade to original/own brand manufacturing (OBM) through accelerated internationalization. We focus on investigating how Lacquer Craft Mfg (later referred to as Lacquer Craft), an OEM firm in southern China successfully upgraded to OBM through reverse acquisitions. By proactively utilizing the resources (including the mindset or perspectives formulated) generated from practicing OEM, Lacquer Craft developed the needed capabilities to build its own brand in an international setting. Lacquer Craft’s successful experiences show that in a globalized economy, the ability to identify and exploit opportunities to link with established players, and the ability to search, acquire, and integrate strategic assets from the developed world rather than replicating the entire previous technological trajectory greatly facilitate the OEM firm in climbing up the value-added ladder and upgrading to OBM. This is a more aggressive upgrading approach. Its experiences also reveal that a firm’s product and technological upgrading strategies are closely interwoven with its internationalization strategy.     

On the relationship between intermediate input imports and export quality in China

This paper studies the connection between intermediate input imports and firms’ export quality using firm‐level data from 2000 to 2007. Our regression results show that intermediate input imports promote manufacturing firms’ export quality through ‘variety effects’ and ‘innovation effects’, though the effects are significantly different among firms with different characteristics, and the magnitude of these effects differs across import sources and the quality of imported intermediate inputs themselves. Moreover, we find that a good institutional environment is conducive to the strengthening of the positive influence of intermediate input imports on export quality. Furthermore, the dynamic decomposition demonstrates that the reallocation effect is the key force through which imported inputs boost industrial aggregate quality growth. Taken together, these results suggest that product upgrading facilitated by quality embedded in imported intermediate inputs, a good institutional environment and market share reallocation help Chinese firms to improve the quality of their export products.     

高管政治关联助推公司媒体报道了吗?—来自民营企业IPO期间的证据

媒体报道对资产定价具有重要影响,致使其日益受到公司管理层的重视.文章以2006?2014年民营企业IPO为样本,基于公司管理层经历或背景,研究高管政治关联对公司媒体披露的影响及其市场效应.研究发现:(1)高管政治关联有助于公司在IPO期间获得更高的媒体关注度和更正面的报道倾向;而且,政治关联层级越高,媒体报道对其越有利.(2)高管政治关联对媒体报道的影响主要通过非证监会四大信息披露媒体和地理邻近媒体来实现的;而地区制度环境可在一定程度上抑制高管政治关联对媒体报道的影响.(3)由政治关联所带来的媒体报道水平的改善,有助于促进IPO首日抑价的上升;但中长期会导致股价反转.文章不仅丰富了公司治理对媒体(信息)披露管理影响方面的文献,而且为民营企业的政商关系研究提供了新的经验证据.
