我国城乡耐用消费品市场用户构成差异的研究——一个创新扩散的视角

创新扩散理论按照用户采用新产品的时间先后顺序将市场细分为创新者、早期采用者、早期大多数、晚期大多数和落后者五种类型。本文在扩散经典理论和中国市场特征的基础上,提出城镇市场和农村市场耐用消费品用户构成差异的假设。研究结果证实了全部假设:城镇的创新者比例显著高于农村,农村的早期采用者比例显著超过城镇,而各类型采用者的采用持续时间农村全面长于城镇。这些结论为更加深入地了解二元经济结构下中国市场的特征提供了有益启示。     

《六书故》引申规律及其影响

关于引申规律的探讨,世人多推许清代学者段玉裁的《说文解字注》,并从中归纳出众多类型。《六书故》是宋元之际戴侗所著的一部字书。本文从《六书故》中找出相应的例证,以说明早于《段注》几百年的《六书故》已能反映和描述这些引申规律。从而说明《六书故》在词义引申规律方面的探讨对后代产生了深远的影响。

Contextualizing the categorical imperative: Category linkages,technology focus,and resource acquisition in nanotechnology entrepreneurship

This paper examines the role of category affiliations in entrepreneurial resource acquisition. Pace existing studies, we suggest category spanning will cause firms to be overlooked or discounted because evaluators assume that they have less expertise than their category-focused competitors; a phenomenon known as the ‘categorical imperative’. We suggest, however, that categories can be related both vertically and horizontally, and that this has important implications for understanding how the actors that span between them are evaluated. Studying startup ventures in nanotube technology, we show that venture capital investments were affected by a firm's position across patent classes that were related at both of these levels of analysis and that the interaction between them had implications for which firms received the largest investments.     

Funding the story of hybrid ventures: Crowdfunder lending preferences and linguistic hybridity

Prosocial crowdfunding platforms are venues for individual lenders to allocate resources to ventures that specifically pursue economic and social value. In a setting where hybridity is expected, do crowdfunders respond positively to category-spanning ventures, or do they prefer to fund ventures that are more clearly situated within a single category? Drawing on theory rooted in category membership and spanning, our hypotheses test whether prosocial crowdfunding lenders will more quickly allocate resources to hybrid microenterprises that communicate their hybridity, or to those that communicate a single one of their dual aims. Our study demonstrates that even in such a setting, crowdfunders lend more quickly to microenterprises that position themselves within a single linguistic category in which the social is emphasized over the economic. This suggests that how hybrid organizations position themselves in their linguistic narratives has a significant impact on resource allocation by external prosocial audiences.     

关于新疆农业旅游发展类型及存在问题的探讨

新疆农业旅游一经开展便迅速发展，目前新疆农业旅游的发展形式主要有“农家乐”型、生态农业观光型、山区森林游憩型、渔禽养殖度假型和农业特产节旅游型。但在新疆农业旅游发展的过程中仍然存在一些问题，如经营者素质参差不齐、旅游产品缺乏文化内涵、环境破坏等。解决问题的根本所在，是要进行规范化管理和进行准确的目标、产品和文化定位。     

居民收入增长对公共支出的需求变动分析——基于中国1978～2006年数据的实证研究

由于不同收入群体的公共产品偏好不同,因此,随着居民收入的增长,公众对于公共产品的需求会有所改变,由此引致的财政支出规模变化应当是＂民生财政＂建立过程中需要重点考虑的因素。本文试图研究中国改革开放以来居民收入增长对财政支出规模的影响,主要从两个层面展开：首先,在理论层面,将财政支出分为不同性质的三类,并以此为基础分析居民收入与财政支出规模二者之间的逻辑关系;接着,对1978～2008年间中国的经验数据进行了实证研究,用协整检验和ARIMA模型等计量工具,实证分析了居民收入增长对中国公共支出结构变动的影响。研究结果表明：长期看来,随着居民收入增长,基础设施需求以及国防安全的需求趋于稳定;在短期中,居民收入的增长最能引起社会文教支出的扩张,其次为国防支出和行政管理支出,对经济建设支出的影响最弱。     

人口老龄化影响了科技创新吗?

我国正进入人口老龄化时代。老龄化对科技创新产生积极和消极两方面的影响,随着老龄化程度的逐步加深,这两方面的影响此消彼长。从宏观层面看,人口老龄化对科技创新产生的影响呈现出倒U型趋势,即随着老龄化程度加深,对科技创新的影响经历先上升后下降的过程。基于我国省级层面的面板数据,使用工具变量回归、差分GMM和系统GMM方法进行了实证研究,研究结果证实了老龄化对科技创新的倒U型影响,并且发现：发明、实用新型和外观设计3种专利形式的峰值年龄不一样,作为根本性创新代表的发明专利的峰值年龄出现得最早。     

浅谈被动语态的种类及用法

一般认为，被动语态主要是通过动词的形式来表示主语与谓语的关系的，只有及物动词才可以用于被动语态，事实并非如此。本文就被动语态的种类及用法作以简要叙述，以便对被动语态有更深的理解并能广泛运用。
