China’s research and development (R&D) policy has changed considerably over recent decades, and great changes occurred in 2006 when the main programme objective of China’s R&D changed from the 863 Programme and 973 Programme to the National Science and Technology Major Project. One topic that has drawn extensive attention is whether the investment reform improved R&D productivity in China. Using a unique panel dataset from 160 universities, this paper examines the effect of the investment reform on productivity improvement in China’s agricultural biotechnology sector. We use a panel count data model with a dynamic feedback mechanism to model the knowledge production process. Strong evidence indicates that the investment reform greatly contributes to knowledge output production in China’s agricultural biotechnology sector. We also find that the input quality is more important than the absolute quantity; human research capacity exhibits the greatest contribution to the output of patents; past knowledge accumulation helps produce more patents; and entry barriers to patent production exist in China’s agricultural biotechnology sector. Moreover, the patent explosion in China may have been largely caused by improvements in the human capital input quality. 相似文献

In the western world, stock markets arose from the search by privately owned companies for capital to build their businesses. Over time, the markets became places where ownership interests and even entire companies were bought and sold. In China, the complete opposite has happened. The markets arose out of the need for capital by bankrupt state‐owned enterprises operating in an economy with no history of private property. Deng Xiaoping, China's last emperor, gave the green light for the stock market experiment in early 1992 more with the hope of encouraging reform and efficiency than from any conviction that stock markets were the next sure thing. Now, after more than 20 years of experimentation with domestic and international listings, it appears evident that stock markets whose primary function is to trade minority interests in government‐controlled companies have not achieved the goal of improving enterprise performance, as China's leaders originally hoped. Instead, the combination of state monopolies with Wall Street expertise and international capital has led to the creation of national companies that represent little more than the incorporation of China's old Soviet‐style industrial ministries. As for the markets, the government's determination to prevent real privatization has produced separate classes of shares that are defined almost entirely by one thing: the shareholder's relationship to the government. And with all aspects of stock market activity regulated, managed, and owned by various state agencies, it is not surprising that non‐state investors have become motivated more by speculative opportunities than by investment fundamentals. But a quarter of a century is a short time in any country's development and, for all their shortcomings, the markets in mainland China and Hong Kong have played a significant role raising capital for China. It may be too early, perhaps, to suggest that China's equity markets have failed to accomplish what they were intended to do. 相似文献

This study develops an efficiency wage model that generates a wage curve at the regional level and a Phillips curve at the national level, under the assumption that workers' efficiency depends on both regional and aggregate labor market conditions. An equation relating wages to unemployment and lagged wages is derived from the profit-maximizing behavior of firms, and it is demonstrated that the coefficient on lagged wages is less than 1 with regional data but equals 1 with aggregate data. In addition, there is an equilibrium relationship between unemployment and wages at the regional level, but not at the aggregate level. 相似文献

By incorporating behavioural sentiment in a model of a limit order market, we show that behavioural sentiment not only helps to replicate most of the stylized facts in limit order markets simultaneously, but it also plays a unique role in explaining those stylized facts that cannot be explained by noise trading, such as fat tails in the return distribution, long memory in the trading volume, an increasing and non-linear relationship between trade imbalance and mid-price returns, as well as the diagonal effect, or event clustering, in order submission types. The results show that behavioural sentiment is an important driving force behind many of the well-documented stylized facts in limit order markets. 相似文献

ABSTRACT This paper examines those factors affecting public attitudes about the O. J. Simpson trial and the American criminal justice system. The separate and combined effects of these factors–which include race, age, gender, income, and education–were estimated using a logit model. It was found that blacks were more likely than whites to be sympathetic to Simpson and to believe he was innocent of the crimes he was charged with. Older individuals, males, those with higher incomes, and those with more education were less likely to be sympathetic to Simpson and more likely to think he was guilty. Finally, it was found that blacks were more likely than whites to perceive that the criminal justice system is biased against blacks. 相似文献

One of the major challenges in the management of innovation is a practical and useful implementation of technology forecasting. This article proposes the concept of aniticpating the technological future, and that a structured approach to this concept could be an invaluable aid to technical decision-making. The notion of technological threat and opportunity assessment is presented as a useful framework for anticipating technological change. This notion is based on a dual approach.Firstly, a rapidly changing global technological landscape necessitates keeping track of technological developments. However, since we are dealing with innovation (rather than mere invention), the market implications are as important as the technological ones and have to be accounted for as such. Secondly, any organisation could be considered to be technology-based to some or other degree, implying that technologies have the ability to affect the bottom line of the organisation in some way. It is thus required to assess the business impact of such technologies, typically through a technology or innovation audit.Having assessed specific technological threats and opportunities facing the organisation, an innovation strategy needs to be developed in response to the identified threats and opportunities. Various possible offensive and/or defensive responses should be considered, culminating in the selection and implementation of an optimal strategy. 相似文献

One of the fundamental problems in strategic management is to map a heterogeneous set of firms in an industry into subsets of firms within which firms are homogeneous in their conduct and performance. The strategic group concept provides an answer to this intriguing question. Researchers in strategic group theory argue that firms within the same strategic group are behaviorally similar and thus tend to compete more fiercely within the group than across groups. In this paper, we focus on the question whether firms within the same group show similar decision‐making characteristics. Strategic‐choice theorists argue that top management teams in firms have substantial discretion in determining the future strategic contour of firms. Upper‐echelon theorists also argue that top managers are the strategists who set the direction of firms and the pace of competition in the industry. Further, they argue that top management team characteristics are an important element that determines the market niche in which a firm competes and the strategic direction a firm follows. Based on these arguments, we expect that there will be a significant link between grouping of firms by the patterns of competitive interactions and grouping of firms by top management team heterogeneity. Moreover, we argue that the closer the TMT heterogeneity of a firm is to the dominant heterogeneity in the competitive interaction group, the better it performs.

Accounting scandals and concerns about the quality of financial statements have led to many calls for improved audit committee effectiveness. Prior research indicates that audit committee independence is positively related to effective oversight of the financial reporting process. Unfortunately, prior research has not provided an answer as to how much independence on the audit committee is enough. This is an important unanswered question because while Section 301 of the Sarbanes-Oxley Act of 2002 (SOX) currently requires all listed companies to maintain an audit committee that is 100% independent there has been much debate regarding easing the SOX requirements for smaller and foreign companies. In this paper we examine whether the regulatory requirements of a completely independent audit committee are necessary to obtain the monitoring benefits related to audit committee independence that have been documented in prior literature. Our results suggest that the benefits of audit committee independence are consistently achieved only when the audit committee is completely independent. These results provide support for the SOX requirement of 100% independent audit committees. 相似文献
