中国对东盟纺织业投资的经济效应分析

中国对东盟纺织服装业的直接投资近年来发展很快。本文从中国对东盟纺织业加强投资的原因分析入手,提出了中国对越南、柬埔寨、印尼、泰国的纺织业投资的路径选择,进而具体分析了投资带来的缓解双方同构性出口竞争压力、提高双方纺织品贸易互补性、促进中国纺织产业结构升级的经济效应。在经济效应分析的基础上．指出中国加强和优化对东盟国家纺织业投资有助于提高中国纺织业整体的核心竞争力。

增值税改革刍议

增值税是我国目前流转税的一大税种，是我国的财政收入的重要来源和国家宏观调控政策的重要手段。本根据现今国际国内形势的发展，提出增值税在现阶段应该改进的一些方面，如税收链条不够完整、小规模纳税人税率设计有待商榷等等，以期完善增值税。     

产业组织的垂直解体与生产者服务业的发展

生产者服务业逐渐从制造业领域分离是当代世界经济发展的重要趋势,是国际分工不断深化的必然结果.通过分析国际分工的演进脉络,论述产业组织的垂直解体对生产者服务业发展的影响,提出我国应从战略高度重视发展生产者服务业;通过降低交易成本,促进分工的外部环境优化,进而促进内部服务业外部化;加强研发、营销环节的发展,促进企业的竞争战略由综合竞争力向核心竞争力转变.

财政分权与义务教育财政管理体制问题探析

我国是成功实施财政分权化的国家之一。作为公共财政框架部分之一的义务教育也实行了分权化管理,义务教育办学的责任主要地落在了县、乡两级地方政府身上。而我国庞大的义务教育事业由县、乡甚至村脆弱的财力来承担,可谓“杯水车薪”：一些农村地区和贫困山区学龄儿童无学可上,无书可读等现象屡见不鲜。可见过度分权化的义务教育财政管理体制是制约当今中国义务教育发展的症结所在。     

区域产业结构与就业结构的比较及启示——基于重庆市万州区和涪陵区的分析

产业结构和就业结构的变化反映出区域经济发展的资源分配结构及其发展进程和水平.分析发现,万州区与涪陵区在产业结构上都存在第一产业所占比重与其吸纳劳动力的比重不一致的现象,其中,涪陵区第二产业比重较大但吸纳劳动力能力较弱,而万州区第三产业吸纳劳动力能力要弱于涪陵区.两地应大力发展第三产业以改善就业结构,充分吸纳从第一产业转移出来的劳动力.     

上市公司可持续发展评价体系构建

目前,我国上市公司业绩评价体系门类繁多,但专门评价可持续发展能力的指标体系尚停留在探索阶段。本文在现有研究基础上,构建了上市公司可持续发展的实现模型,并选取定量指标,采用变异系数总指数法赋予权重,建立了上市公司可持续发展评价体系。以2003年我国电子行业上市公司为样本进行检验,结果发现,其结果与《2003年度中国上市公司业绩评价报告》具有一致性。     

Nonlinear IV unit root tests in panels with cross-sectional dependency

We propose a unit root test for panels with cross-sectional dependency. We allow general dependency structure among the innovations that generate data for each of the cross-sectional units. Each unit may have different sample size, and therefore unbalanced panels are also permitted in our framework. Yet, the test is asymptotically normal, and does not require any tabulation of the critical values. Our test is based on nonlinear IV estimation of the usual augmented Dickey–Fuller type regression for each cross-sectional unit, using as instruments nonlinear transformations of the lagged levels. The actual test statistic is simply defined as a standardized sum of individual IV t-ratios. We show in the paper that such a standardized sum of individual IV t-ratios has limit normal distribution as long as the panels have large individual time series observations and are asymptotically balanced in a very weak sense. We may have the number of cross-sectional units arbitrarily small or large. In particular, the usual sequential asymptotics, upon which most of the available asymptotic theories for panel unit root models heavily rely, are not required. Finite sample performance of our test is examined via a set of simulations, and compared with those of other commonly used panel unit root tests. Our test generally performs better than the existing tests in terms of both finite sample sizes and powers. We apply our nonlinear IV method to test for the purchasing power parity hypothesis in panels.     

Managing academic innovation in Taiwan: Towards a ‘scientific-economic’ framework

Since the passage of the Science and Technology Basic Law in 1999, Taiwanese universities have taken a more “scientific-economic” approach to protect and commercialize their research. This research mainly examines innovation activities such as patenting, licensing, and incubated startups in the context of Taiwanese higher education institutions (HEIs). The “scientific-economic” framework used to analyze the strategic aspects influencing these academic innovations includes (1) intellectual property managerial capabilities, (2) the strength of external industrial partnerships, (3) the university entrepreneurial orientation, and (4) government research policy. Four hypotheses were developed. Data were collected via a questionnaire with all 122 HEIs in Taiwan surveyed.The research reveals that the aspects of intellectual property managerial capability, HEI-industry partnerships, and academic entrepreneurial orientation are useful to distinguish the university's innovation performance on patent grants, licensing incomes, and firm incubation. Also, government support on research plays a moderating role in academic innovation. Managerial and policy implications for managing innovation effectively in universities were drawn.
