市场导向、创新与企业表现的关系——基于中国服务业的实证研究

市场导向的采用可以产生良好的企业表现等命题已被广泛接受,然而,二者之间具体关系的实证分析尚还不足,尤其是中国服务业中二者的具体关系研究几乎空白。本文以中国服务业企业为研究对象,提出了市场导向、创新与企业表现关系的假设模型,根据570个服务企业样本数据,利用回归分析及结构方程模型进行了检验,发现中国服务业中市场导向是通过创新的介入与递推而对企业表现发挥作用的。因此,中国服务业企业在市场导向的应用过程中要注意对创新活动的支持,这样才能充分发挥市场导向的作用。     

Building a performance-based environmental management system: EPA's reinvention efforts revisited

A new U.S. Environmental Protection Agency (EPA) report recommends the Agency do more to help well-meaning companies comply with the law and encourage those that are willing and able to do even more. Since 1996, major stakeholders have achieved consensus on the need and desire to create a ‘performance-base’ environmental managemeny system. Whereas most agree that a performance-based system is necessary for the future, few agree on when or how the EPA should design and implement it. The design of a new performance track, one developed and operated in parallel with the existing regulatory system, utilizing emerging environmental management techniques and complementary policy developments, is close at hand, but needs reinvigorated support to be applied on a greater scale and with more confidence.In this article, the first in a two part series, Monsma and Mazurek show why the design and implementation of a new, federal performance-based environmental management track should not be deterred. Drawing from the lessons of prominent EPA pilot programs such as 33/50, the Common Sense Initiative, and Project XL, the authors identify a set of lessons for a performance-based system. In part two of the series (to appear next issue) the authors will discuss the political economics of reinvention and try to determine the best means out of the current maze.     

Is your information system mature enough for computerized planning?

This paper presents the results of a study of computerized planning models in 235 firms throughout the world. The authors argue that organizational climate can be a serious pitfall to the inplementation of long-range planning systems. However, their view of climate extends beyond the traditional behavioral domain to include the sophistication of the organization's information system. The paper addresses itself to one of the key questions affecting the implementation of long-range planning systems. Why do some organizations develop computerized planning models and others do not?     

Pitfalls in multi-national long-range planning

The authors of this article argue that too many companies are not getting the benefits which should be produced by their long-range planning systems. Of the many possible explanations for this, the authors concentrate on the major pitfalls which should be avoided in order to ensure good results. The article is based upon the results of a survey of planning pitfalls among corporations in six industrialized countries.     

Developing a planning culture for more effective strategic planning

The literature of long-range planning is replete with justifications of the need for strategic planning and admonitions concerning its critical importance. However, both the literature of planning and its practice, as manifested in a variety of organizations as diverse as industrial firms, educational systems and law enforcement agencies, are deficient in specifying proven techniques and methodologies for marshalling organizational resources to effectively implement strategic planning.Over a period of years, the authors have consulted with a variety of business organizations and public agencies in the development and implementation of long-range planning processes. From this work has come an empirically-tested conclusion that the success of long-range planning in an organization is less sensitive to the parameters of the planning techniques that it is to the overall culture within which the planning is accomplished. Since most of the non-pontifical literature of planning focuses on planning techniques and specifications for planning processes, these conclusions suggest a critical void in planning methodology.     

Environmental Surveillance at Los Alamos: An Independent Reassessment of Historical Data

Since 1971, a series of annual Environmental Surveillance ... reports have served as the official public record of Los Alamos National Laboratory's (LANL) environmental performance. In northern New Mexico, where past LANL emissions are a public health concern, there is public skepticism over the accuracy of information contained in these reports. To test the hypothesis that LANL Environmental Surveillance ... reports systematically understate past emissions, we compared the data on releases in LANL's own internal Occurrence Reports Collection (ORC) to the data reported to the public in the Environmental Surveillance ... reports. A data set of 89 environmental occurrences recorded in the ORC in the time period from 1971 through 1980 was assembled. We did not find a systematic pattern of quantitative underreporting of source terms. However, 17 of the 89 (19%) environmental occurrences recorded in the ORC were not reported to the public in the Environmental Surveillance ... reports. The observed discrepancies are discussed in terms of their relevance to public health concerns. Methodological caveats dictate restraint in applying these findings beyond the scope of the relative comparison performed here. Possible social origins for the rejected hypothesis are discussed. Areas for further consideration by the Centers for Disease Control's dose reconstruction study of LANL are identified.     

A systematic literature review of mining weak signals and trends for corporate foresight

Due to the ever-growing amount of data, computer-aided methods and systems to detect weak signals and trends for corporate foresight are in increasing demand. To this day, many papers on this topic have been published. However, research so far has only dealt with specific aspects, but it has failed to provide a comprehensive overview of the research domain. In this paper, we conduct a systematic literature review to organize existing insights and knowledge. The 91 relevant papers, published between 1997 and 2017, are analyzed for their distribution over time and research outlets. Classifying them by their distinct properties, we study the data sources exploited and the data mining techniques applied. We also consider eight different purposes of analysis, namely weak signals and trends concerning political, economic, social and technological factors. The results of our systematic review show that the research domain has indeed been attracting growing attention over time. Furthermore, we observe a great variety of data mining and visualization techniques, and present insights on the efficacy and effectiveness of the data mining techniques applied. Our results reveal that a stronger emphasis on search strategies, data quality and automation is required to greatly reduce the human actor bias in the early stages of the corporate foresight process, thus supporting human experts more effectively in later stages such as strategic decision making and implementation. Moreover, systems for detecting weak signals and trends need to be able to learn and accumulate knowledge over time, attaining a holistic view on weak signals and trends, and incorporating multiple source types to provide a solid foundation for strategic decision making. The findings presented in this paper point to future research opportunities, and they can help practitioners decide which sources to exploit and which data mining techniques to apply when trying to detect weak signals and trends.     

On the use of multivariate regression methods for longest path calculations from earned value management observations

This paper explores the use of multivariate regression methods for project schedule control within a statistical project control framework. These multivariate regression methods monitor the activity level performance of an ongoing project from the earned value management/earned schedule (EVM/ES) observations that are made at a high level of the work breakdown structure (WBS). These estimates can be used to calculate the longest path in the project and to produce warning signals for project schedule control. The effort that is spent by the project manager is thereby reduced, since a drill-down of the WBS is no longer required for every review period. An extensive computational experiment was set up to test and compare four distinct multivariate regression methods on a database of project networks. The kernel principal component regression method, when used with a radial base function kernel, was found to outperform the other presented regression methods.     

Technological forecasting for power generation—A study using the Delphi technique

Technological forecasting is a powerful technique for obtaining insights into possible futuristic innovations. The forecast can provide a basis for long-range planning and policy formulation in organizations. Technological forecasting, though a useful and powerful tool, has yet to be applied widely in developing countries. This paper outlines a forecasting exercise carried out by the authors using the Delphi technique in India. The focus of the exercise was on electric energy generation and transportation. The findings have been compared with other available studies in India in similar areas. The paper also illustrates how additional information inputs can mould such forecasts. For this purpose, the authors have compared the results of the current study with the results of a similar study carried out in the same organization 8 years earlier. The change in perception regarding the timing of certain items is very evident and the underlying reasons have been given.

Interorganizational Determinants of Environmental Purchasing: Initial Evidence from the Consumer Products Industries*

Environmental purchasing consists of the purchasing function's involvement in activities that include reduction, recycling, reuse, and substitution of materials. Despite the potentially important role that the purchasing function can play in a firm's environmental activities, little research has been performed to date that examines the factors that impact environmental purchasing. The authors develop and empirically test a theoretical model that examines how interorganizational factors both drive and constrain purchasing's involvement in environmental activities. The empirical findings suggest that environmental purchasing activities will be facilitated through increased coordination with suppliers as well as downstream members of the supply chain, including retailers. The results also suggest the need for increased coordination within the firm, particularly between the purchasing function on the inbound side and marketing and distribution functions on the outbound side.

Corporate long-range planning groups—Some different approaches

This paper investigates several atypical roles of formal long-range planning groups and some reasons for their appearance. The study is based on three separate surveys covering 115 companies in eight industries located in both England and the United States. The authors first identify functions based on their own research and the literature which appear to make up a typical planning group role. Twenty-four of the 115 planning groups surveyed very considerable as well as sytematically from the norm. They are classified into three major categories described as (1) capital budgeting groups, (2) project development groups, and (3) think tank groups.     

Improving the efficiency of IT help-desk service by Six Sigma management methodology (DMAIC) – a case study of C company

Six Sigma concept depicts a ‘Triangle Relationship’ that integrates three attributes such as customer quality, science manners and team work. By employing this concept with the required survey and data collection to carry out the continuous improvement, a company can truly take advantage of the minimum set of operational variables and the lowest cost procedures, and hence, result in an increasing competitive value for/to the company. This research is conducted based on the Six Sigma methodology, DMAIC (definition, measurement, analysis, improvement and control) principle, and it deals with project-related issues to improve the efficiency of information technology (IT) help-desk service through an eHelp-desk system. It is the authors’ belief that the use of eHelp-desk system can help case company to improve its service quality and efficiency. In addition, managerial implications and research limitations are discussed at the end of this article.     

Greening the health care supply chain: Triggers of change,models for success

A historic agreement signed in July 1998 between the American Hospital Association (AHA) and the U.S. Environmental Protection Agency (EPA) signals changes in waste management in the health care industry. The agreement, which calls for a fifty percent reduction of hospital waste by 2010, will not only have an impact on hospital facility managers, but throughout the entire healthcare supply chain. As this article argues, improving the environmental impact of the health care industry should start with the health care delivery institutions themselves. The health care industry has a long way to go in addressing its environmental impacts, compared to the energy and chemical industries, for example. One reason is that these industries are raising their suppliers' environmental performance. Health care delivery institutions can effectively pull environmental performance requirements through the entire supply chain as well. This can be accomplished by examining supply chain strategies of leading industries and firms and considering the role of environmental management systems such as a ISO 14001 throughout the entire chain.     

Safety Risk Analysis of an Innovative Environmental Technology

The authors describe a decision and risk analysis performed for the cleanup of a large Department of Energy mixed-waste subsurface disposal area governed by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). In a previous study, the authors worked with the site decision makers, state regulators, and U.S. Environmental Protection Agency regional regulators to develop a CERCLA-based multiobjective decision analysis value model and used the model to perform a screening analysis of 28 remedial alternatives. The analysis results identified an innovative technology, in situ vitrification, with high effectiveness versus cost. Since this technology had not been used on this scale before, the major uncertainties were contaminant migration and pressure buildup. Pressure buildup was a safety concern due to the potential risks to worker safety. With the help of environmental technology experts remedial alternative changes were identified to mitigate the concerns about contaminant migration and pressure buildup. The analysis results showed that the probability of an event with a risk to worker safety had been significantly reduced. Based on these results, site decision makers have refocused their test program to examine in situ vitrification and have continued the use of the CERCLA-based decision analysis methodology to analyze remedial alternatives.     

Long range planning of U.K. and Japanese corporations—A comparative study

The author conducted mail surveys on long-range planning systems in Japanese and British corporations. He also made a number of visits to corporations in both countries to analyse the similarities and differences in the planning systems.In the U.K., the clarification of goals and the resource allocation are emphasized but in Japan clarification of goals and basic problem finding are stressed.The strategic projects are not necessarily formulated in the long-range planning process. The relationship between the project and the long-range planning was analysed and in both countries, the trend of long-range planning is towards more strategy orientation than quantitative computation.The planning process in Japan is more centralized. The management committee plays an important role in reviewing and making the final decision. In the U.K., the plan initiation is more decentralized, and in the final decision the board of directors plays a more important role. The trends are, however, from bottom up approach to top down approach.Goals expressed in the long-range plan of the U.K. corporations put more emphasis on financial goals, but that of the Japanese corporations emphasizes growth and employee welfare.Regarding the style of strategic decision-making the subjective responses show that it is partly analytical and partly intuitive. There are some differences between two countries, but this problem needs to be analysed further.To cope with uncertainty, multiple scenarios and contingency plans are more frequently used in the U.K., whereas in Japan the sequential decision is more commonly used. British corporations are better prepared for uncertainty than Japanese corporations.The key success factors of long-range planning are similar in both countries. The involvement of top management and cooperation of line management are two important items. Differences are that in the U.K. the planning system is emphasized in addition to the other factors, but in Japan clear goals are more emphasized.     

Global development on environmental performance indicators

The call for greater corporate accountability and transparency is affecting companies around the globe. As the demand increases for uniformity in corporate environmental reports, respected WRI researchers Janet Ranganathan and Daryl Ditz (now with the Environmental Law Institute) argue for a set of four environmental performance indicators: materials use, energy consumption, non-product output, and pollutant releases. Countries, such as The Netherlands, are finding that sets of environmental indicators are useful in developing nationals goals. As discussed in “Communicating Environmental Performance to the Capital Markets,” by Linda Descano and Bradford Gentry in this issue, it is essential for the investment community to understand the link between environmental performance and business value.
