评价中国制造业国际竞争力的实证方法研究--兼与波特指标及产业分类法比较

本文应用内容分析法,对近年来发表在国内权威和核心期刊上有关中国制造业国际竞争力评价的重要实证文献进行了回顾与综述,分析了这些实证研究中存在的问题和可取之处,并就两个关键点进行了探讨一是在进行产业国际竞争力的评价时,应该如何选取方法和指标;二是在对中国制造业的国际竞争力进行实证研究时,应当采用何种产业分类法。经过对产业竞争力四个层次的划分及与波特方法的比较,得出对中国制造业的国际竞争力进行评价的方法结论以产业利润率、全球市场份额和劳动生产率/平均工资率三者为评价指标;用相当于ISIC二分位的国内28个制造业部门进行产业分类。     

中国制造业产业集聚的实证研究

文章利用集中度、基尼系数、赫芬达尔指数(N指数)等指标,对中国20个二位数制造业门类的集聚性进行了实证研究,并对其中5个门类进行了细化研究,得出结论:中国部分制造业已显现出较强的集中性,且主要集中在东部沿海省市,但一些规模经济和范围经济性强、在国外具有显著集聚特征的行业的集聚性还比较低。     

我国制造业的对外开放与国家经济安全

随着商品、技术和投资等方面对外开放程度的不断扩大，我国制造业日益融入国际分工体系之中。即使是在经济全球化不断深化的今天，国家仍然是最重要的经济利益主体，由于制造业在国民经济中无可替代的重要地位，制造业对外开放必然会对国家经济安全产生深刻影响。     

虚拟建设的发展、内涵与组织管理流程

再谈环境保护税设置——基于两类竞争制造企业环保技术创新策略的演化博弈

利用演化博弈模型分析处在竞争的两类制造企业(在位企业和进入企业)的环保技术创新策略问题,考量以环境保护税为主体的环保规制如何科学设置才能更好地促进制造业企业的环保创新.研究发现:创新效应和市场需求均影响企业创新策略演化的均衡结果,并在两阶段博弈分析的基础上,得出市场需求和创新效应共同作用下两类制造企业的生产策略选择方案.因此,环境保护税的改革与实施应注意掌握好时点,税率的设置应充分考虑不同行业环保创新效应和产品市场需求,进行区别化的、动态的税率设置,并加大其他税种对环境保护税的支持.     

Carbon Disclosure,Financial Transparency,and Agency Cost: Evidence from Chinese Manufacturing Listed Companies

Given the constraints on carbon emissions due to their impact on global warming, carbon disclosure has become an important way to deliver signals to the market. We examine the benefits associated with carbon disclosure from the standpoint of corporate social responsibility (CSR) for China’s manufacturing industries from 2010 to 2014. We divide corporations into heavily polluting and non-heavily polluting groups in order to control the industry factor. Based on the Principal-Agent Theory, we empirically test the relationship between carbon disclosure and financial transparency, and we evaluate the effect of carbon disclosure on agency costs and operations. Our results highlight that carbon disclosure is negatively associated with agency costs. However, we do not find enough evidence to prove what role financial transparency plays in the relationship between carbon disclosure and agency cost. Therefore, the influence of financial transparency as a mechanism is not yet clear. This study provides a way to look at the intentions of firms that disclose carbon information, and it also enhances the literature on carbon disclosure and agency costs in China based on Chinese data.     

What makes export manufacturers pursue functional upgrading in an emerging market? A study of Chinese technology new ventures

This study examines unique factors causing emerging market firms to pursue functional upgrading. Our analysis draws on the resource-based view and learning theory, and our study sample consisted of Chinese new technology ventures. We test the effect of governance mechanisms and internal resources on the functional upgrading of firms. The results indicate that trade shows and quality advantage facilitated the functional upgrading of firms. However, contrary to our expectations, electronic markets and technological advancement do not emerge as significant variables. The implications of the results are discussed in consideration of the existing literature, and future research opportunities are described.     

Competitive strategies,innovation, and firm performance: an empirical study in a developing economy environment

This paper studies the relationships between competitive strategies, innovation, and firm performance within the context of Turkish manufacturing companies. The data were collected from top management of the firms via Computer Assistant Telephone Interviewing method. One hundred and forty manufacturing firms operating in various sectors including textile, automotive supply, computer and electronics provide the basis for this empirical research. In order to test our model, we employ structural equation modelling using partial least squares. The results show that competitive strategies such as cost-leadership and differentiation can lead to innovation, which, in turn, increase firm performance. Managers implement cost-leadership and differentiation strategies to take part in competitive market conditions; however, they should put additional importance on innovation that plays a significant role as a bridge between competitive strategies and firm performance.
