构建基于DLLs的可扩展软件结构

程序的运行完全绕开编译器是不可能的,但可以把那些来自DLL库、用于驱动设备的函数或其他目的性很强的函数从主程序中分离出来,实现一种可扩展的软件构架,即不在程序中直接调用函数,而是将需要调用函数写在一个脚本里,在程序运行时去读这个脚本,根据脚本的内容载入相应的动态连接库并执行其中的函数,这样就形成了一种灵活的软件结构,使软件的可伸缩性得到改善。本文介绍在C++源程序中嵌入汇编语句来构建基于DLLs的可扩展软件结构的方法,并提供部分源代码。     

我是怎样走上知识产权研究之路的？

一、我是怎样开始学外文的 在已不是闭关锁国的中国,学术研究要有深度和广度,不掌握一门以上外文是难以做到的,知识产权研究尤其如此。而提起我真正学习外文之始,我就常想起20多年前的一次出国前外语口试。 那是1979年末的一天。中国社科院与北京大学一道,在北大法律系的一间教室里,对刚刚通过了法学所出国外语笔试的几位研究人员进行外语口试。主考

Generic and specific social learning mechanisms in foreign entry location choice

We combine economic and institutional theories of clustering in foreign entry location choice in an overarching social learning conceptualization. Prospective entrants learn about the attractiveness of alternative locations by observing the entry choices of previous investors (‘models’). We distinguish two types of learning that differ in observational focus width but can and do operate simultaneously. With assessment learning, firms judge the economic feasibility and agglomeration benefits of entering a location by observing and following a broad set of models. With bandwagon learning, firm‐level uncertainty narrows attention to, and prompts the following of, specific models, with recentness of model behavior an important moderator. We find broad support for our conceptualization in an analysis of the entries of 692 Japanese electronics firms into Chinese provinces during 1979–2001. Copyright © 2011 John Wiley & Sons, Ltd.     

Outward foreign direct investment by emerging market firms: A resource dependence logic

This study examines and extends the resource dependence logic of diversification for a better understanding of outward foreign direct investment (OFDI) activities by emerging market firms. We contend that the diversification logic is bounded by state ownership, an important but less considered component of interdependence. Our empirical results, based on panel data analysis of Chinese listed firms, suggest that the level of interdependence between Chinese and foreign firms in China in multiple forms, including symbiotic, competitive, and partner interdependencies, is positively associated with the level of the Chinese firms' OFDI activities. However, Chinese firms with higher levels of state ownership are less susceptible to the pressures imposed by foreign firms to invest abroad. Copyright © 2013 John Wiley & Sons, Ltd.     

Confidence in learning: Inter‐ and intraorganizational learning in foreign market entry decisions

From an organizational learning perspective, we argue that the information signaled by the distribution attributes of foreign investors already operating in a location will influence the entry decisions of later arrivals by affecting their level of confidence in imitating. In the context of foreign investment decisions, the proportion of experienced firms in a location was shown to first increase a follower firm's confidence about imitating them, but then to decrease it, due to anticipated competition. The impact of learning from target organizations also varies with the experience of the learning organization. Data on the location choices of 7,478 manufacturing ventures in China by U.S. firms supported the hypotheses. The results provide a more integrated and nuanced understanding of learning in foreign direct investment. Copyright © 2014 John Wiley & Sons, Ltd.     

Learning from foreign investment by rival firms: Theory and evidence

We offer an alternative explanation for follow-the-leader behavior in foreign investment decisions based on Bayesian learning by rival firms. We test the implications of the model through a panel count data sample of MNEs that have invested in Central and Eastern Europe over the period 1990–1997. Interacting the measure of rivals' investment in country-industry pairs with uncertainty, we are able to identify the channel of Bayesian learning about revenue postulated by the model as the only one consistently generating the detected follow-the-leader behavior of foreign investments. The empirical findings are robust with respect to different model specifications.     

Demand for sex-oriented cable TV in the USA : Community acceptance and obscenity law

This pooled cross-sectional/time series analysis focuses on individual consumer demand for sex-oriented pay cable programming using data obtained from Coaxial Cable in Columbus, OH. The results suggest that adult movies garnered more demand from pay-per-view subscribers than any other type of programme offered, indicating that sex- oriented cable movies has achieved a reasonable degree of community acceptance. These results are not very encouraging for those who would like to see adult content of this type eliminated from cable television.     

社会学习与消费升级——来自中国电影市场的经验证据

文化服务产业消费“扩容”与“提质”对于中国当前消费升级至关重要。以2012—2016年中国1854部电影为研究对象,本文将每日电影院层面票房数据汇总至全国层面,构建“电影—日”全国票房数据。为避免弱工具变量问题,采用新近发展的套索(LASSO)回归选择最优的天气与空气污染变量作为电影首映周非预期票房的工具变量,识别了社会学习对电影跨期消费增长的影响。研究发现:受外生冲击影响的电影首映周非预期票房变化对于后续周票房存在显著的正向跨期溢出效应,且该溢出效应随着时间推移而逐渐减小。进一步地,制作质量越高、事前质量信息不确定性越高以及市场偏好越集中,电影消费的跨期溢出效应就越明显。这一结果表明,社会学习是引致电影消费跨期溢出效应的主要机制,观察学习与社会网络外部性等机制并未得到实证证据的支持。总体而言,本文揭示了社会学习是影响电影消费“扩容”与“提质”的关键因素,从个体间微观互动机制这一全新视角为激发中国新一轮消费升级提供了可行的实践路径。     

Ambidextrous balance and channel innovation ability in Chinese business circles: The mediating effect of knowledge inertia and guanxi inertia

Drawing on organizational learning theory and literature on guanxi, this study examines how and why ambidextrous learning balance influences firm innovation capability in Chinese business circles. We propose a U-shaped relation between ambidextrous learning balance and firm innovation capability which is mediated by guanxi inertia and knowledge inertia in different ways. Specifically, ambidextrous learning balance has an inverted U-shaped impact on guanxi inertia and further influences firm innovation capability. Whereas, ambidextrous learning balance has a linear positive influence on innovation capability through a decreased level of knowledge inertia. Based on survey data collected from, The results obtained from a sample of 197 Chinese channel enterprises using SEMs analysis provide strong support for our hypotheses. In addition, the findings based on firms with unbalanced ambidextrous learning indicate that as opposed to exploratory learning, higher level of exploitative learning leads to an increase in guanxi inertia and a decrease in knowledge inertia. These conclusions reveal how ambidextrous learning balance influence innovation capability for a firm with inherent learning preference which is not discussed by the extant research. At the same time, this study fills the gap of ambidextrous learning balance by considering the influence of culture. Our work also informs foreign practitioners of the optimal ways of learning for innovation in China.     

Motivations and barriers of foreign R&D activities in China

The continued growth of the Chinese economy accompanied with the expansion of international investment in China has led to an increase in foreign research and development (R&D) activities in the country. Aside from the rising importance of R&D internationalization, research on foreign R&D in China has been neglected in the past due to its emerging status. In this article we examine drivers and barriers for conducting R&D in China. The focus of our research is on transnational companies typically characterized by decentralized R&D activities. Our research is mainly based on qualitative interviews with senior R&D managers. The success of foreign R&D activities in China strongly depends on the realistic estimation of its advantages and the proper identification and handling of barriers.     

COVID-19 and changes in content usage behavior: The case of South Korea

This study examines changes in content usage time due to the COVID-19 pandemic in South Korea using Korean Media Panel data for the period 2011–2020 and explores the reasons for these changes. This study focuses on four principal contents: television programs, movies/videos/user-created content, traditional telecommunication services, and chatting/messenger/social network services. The empirical results indicate an increase in usage time for the four principal contents, as well as total content usage time because of the pandemic. The results also show that average Korean people stayed longer at home after the onset of the pandemic, leading to an increase in the time spent on all the principal contents, except for traditional telecommunication services, as well as an increase in total content usage time. Furthermore, this study suggests that whereas the effect of the pandemic on television program viewing time was mainly attributable to changes in time spent at home because of the pandemic, the effect on other contents was mainly caused by non-location-related factors. This study predicts changes in content usage time after the end of the pandemic and provides strategic suggestions.
