The purpose of this paper is to identify the major determinants of innovation and to examine whether they affect small firms differently than large firms. Using a cross-section of 247 four-digit SIC industries, we present an econometric analysis testing the hypothesis that innovation rates in 1982 were significantly influenced by market structure, and that these influences had disperate effects among large and small firms. We find that, while market structure does explain the variation in innovation rates across industries, the relationships are not always consistent with certain previously maintained hypotheses. Similarly, we find that innovation activity for large firms responds to a different market activity than does innovation for small firms. 相似文献

当2004年初接任技术巨擘摩托罗拉公司的董事长兼首席执行官(CEO)时,EdZander一定感觉得到,即使是在观看魔术表演或者打保龄球时,自己脖子上依然绕着一根无形的、随时可能勒紧的绳索.这位此前担任Sun Microsystems公司总裁兼首席运营官(COO)的先生入主摩托罗拉公司时,公司的主打业务--手机业务正一而再、再而三地错过主导市场、功能升级以及至关重要的铺货时间.摩托罗拉公司的第二大业务部门--半导体部门,自2000年来一直处于亏损状态. 相似文献

《Telecommunications Policy》1998,22(1):57-71
Three goals of the 1996 Telecommunications Act are competition, efficiency, and explicit mechanisms to further universal service. The new universal service policies violate these goals. I review the policies (support for highcost and rural areas, low-income subscribers, and educational and medical institutions, and the funding mechanism) and detect the influence of various interest groups and the regulators' desire to protect their policies from public scrutiny. The new policies will require $4–12 billion per year to fund and create inefficiency of $1.2–4.0 billion per year from revenue taxation. A more efficient tax scheme would increase total surplus. 相似文献

Despite profound changes in regulatory jurisdiction over telecommunications, in industry structure and in the basis on which service is provided, there has until very recently been no change in governing legislation in Canada, which dated back to the turn of the century. This article seeks to explain why the legislature, even in a parliamentary system of government, lagged behind the courts, the regulators and the carriers in bringing about industry reorganization. It then examines a number of the more significant provisions of the new legislation, which was eventually passed in June 1993, and concludes with some general observations on the role of legislation in industry liberalization. 相似文献

R. Craig Matthiessen 《Process Safety Progress》1992,11(2):99-101
The Clean Air Act Amendments of 1990 enacted recently contain provisions for the prevention of chemical accidents under Title III—Hazardous Air Pollutants. Some of these provisions include: a general duty clause, preparation of a list of substances and thresholds, requirements for the preparation of risk management plans by industry, specific accident prevention regulations, establishment of a Chemical Safety and Hazard Investigation Board, and requirements for the Occupational Safety and Health Administration (OSHA) to promulgate a process safety management standard. These provisions, approaches with respect to process safety management by the Environmental Protection Agency (EPA), and coordination with OSHA will be discussed. 相似文献

邢台市污水处理厂在总结一期工程采用土地处理工艺存在的占地面积大、管理不便等主要因素的基础上,二期工程采用了占地少、投资省、运转灵活的交替式活性污泥处理工艺。该工艺不仅吸收了SBR工艺的主要技术特点,还可以像传统活性污泥法那样在恒定水位下连续运行。该工艺将多个单元工艺池巧妙地组合,构成一体化的池组,并采用先进、可靠的高度自控系统实现污水生物法处理。 相似文献

Agricultural policies in Western Germany are characterized by a strong tendency to support domestic producers at the expense of other groups in the country's political system. German politicians, lobbyists, bureaucrats, academics and the church alike are strong supporters of the agricultural sector, which is viewed as the provider of essential requirements and the guarantor of social stability. Consequently, in an attempt to preclude protests by possible ‘reformists’ to policies pursued in the farm sector, Germany's major political actors have put forward convincing arguments for the legitimization of agricultural interests. These arguments are exclusively based on sociopolitical criteria rather than on economic logic. 相似文献
