统筹城乡发展是对完善社会主义市场经济体制的有效探索

中国建设社会主义市场经济体制的探索,经历了一条先农村、后城市,然后进行统筹城乡综合改革三大阶段。统筹城乡发展成为探索中国推进制度转型发展,完善社会主义市场经济体制的重大战略。统筹城乡发展对社会主义市场经济体制完善的主要路径是政府主导建立社会主义城乡统一大市场,规范市场运行,弥补市场失灵,同时推进基层民主建设以弥补集权管理制度不足。制度贡献将成为统筹城乡发展对推进国家现代化进程的最大贡献。     

消除白色污染的对策探讨

白色污染已经成为当今环境保护领域里的大问题。国家为此制定了一系列的政策法规，各级地方政府也出台了“禁白”措施，但效果不尽人意。本文对“白色污染”的发生和对策进行了探讨，认为“禁白”不是最好的治理办法，应该在回收和再利用方面作努力。     

Entrepreneurship through a qualitative lens: Insights on the construction and/or discovery of entrepreneurial opportunity

This article applies inductive analytic techniques to identify and elaborate on two recurring themes that underpin the core puzzle of entrepreneurship research — where entrepreneurial opportunities come from. The first theme is the unique role of imprinting, or the profound influence of social and historical context in constraining the perceptual apparatus of entrepreneurs and delimiting the range of opportunities for innovation available to them. Second, our analysis offers insight into the counterbalancing role of reflexivity, operating at both individual and collective levels of analysis, in generating the ability of entrepreneurs to overcome the constraints of imprinting. These insights are based on a thematic review of the nine studies that comprise this special issue on qualitative research. The nine studies, individually and each in their own way, offer key insights into how we might better understand the emergence of entrepreneurial opportunity.     

Editorial: Purchasing and innovation: Past,present and future of the field of research

This paper introduces the special topic forum (STF) on purchasing and innovation. Presenting the findings from a systematic literature review, we take stock of the current state of the field, delineating themes, theories and methods, and identifying key trends over time. Our study shows a take-off in research on purchasing and innovation during the last decade. This has predominantly focused on private sector manufacturing firms although a recent expansion into public sector research is evident. Large-scale surveys and case studies are still the dominant research methods where the unit of analysis is typically the ‘firm’ or ‘project’. The findings also show how in the past the field was driven by questions on how purchasing can facilitate different types of innovation projects, seeking to derive practical implications, and rarely making explicit statements regarding theories applied; this still characterises much of the research but we find an increasing focus on theory development. We also see a shift in the type of technological innovation being investigated: past studies tended to focus on the role of purchasing in new product development (NPD) projects, which reflected a relatively low degree of technological uncertainty, but we see a trend towards innovation projects facing technological uncertainty. Research shows how this requires new ways of sourcing innovations and therefore new ways for purchasing to facilitate innovation sourcing. On the basis of the review, we offer our guidance for future research avenues to 1) carry out more research on procurement of innovation in the public sector; 2) consider new theories and research methods, and 3) go beyond firm-level or dyadic analysis to research networks and ecosystems. We conclude by introducing the papers in the STF.     

Comparative research in industrial relations: helping the survey cross frontiers

There has been a relative dearth of comparative, cross-national research which has followed a survey-based approach. This partly reflects the difficulty that researchers encounter in collecting such information, either via primary collection or the secondary matching of existing survey material. This paper addresses these difficulties and suggests ways in which their impact can be minimized. It notes that such difficulties are much more severe in the case of secondary matching and are thereby likely to constrain the scope of this approach. They are not totally absent in primary collection and it is suggested that there are limits to what can be achieved during data collection to promote the development of like data-sets across countries. This indicates that great care must be taken in interpreting data so obtained. Despite such limits and cautions, it is nevertheless concluded that the survey approach can be an important adjunct to the process of understanding why the world of work varies across frontiers.     

The influence of activity importance and similarity on perception of recreation substitutes

Abstract

This study examines how substitutes are selected for a fly‐angling and camping recreation activity. Results show that although people choose substitutes similar to their intended activity, the degree of similarity between substitute and original is unrelated to perceived quality of substitute. Also, both the quality of a substitute and the number of available substitutes are inversely related to the importance of an activity's attributes. The lack of a relationship between activity/substitute similarity and quality of the substitute poses problems for application of the substitutability concept.

Book Review

Following review of definitions of New Public Management (NPM), the paper assesses whether Canada has adopted the NPM, organized by Kernaghan and Charih's (1997) categories and using Loeffler's (1997) definition. Canada has reorganized the machinery of government, changed management methods and reduced the federal public sector substantially. Despite high debt, Canada's federal government reduced its expenditures and/or public service as much or more than the UK and New Zealand. Its expenditures as a proportion of GDP are now similar to those of the UK and New Zealand, the major proponents of NPM.
