Inter-industry Technology Spillover Effects in China： Evidence from 35 Industrial Sectors

The present paper calculates 35 industrial sectors’ similarity matrices for the period of 1997-2008 using China’s input-output tables for 1997,2002 and 2007,and uses these to measure inter-industry technology spillover to analyze the spillover effects on industrial sectors’ labor productivity.The empirical analysis shows that inter-industry technology spillover has a significant positive effect on the labor productivity of each industry.The elasticity of productivity effects of inter-industry technology spillover is not only larger than that of direct R&D input,but also increases over time.We group the industries into four major categories and find that the inter-industry technology spillover effect within the categories is,on average,greater than that between the four categories,indicating that technology spillover occurs more easily between similar industries.This research shows that the interindustry technology spillover effect in China has begun to increase,and the government should take advantage of this effect.     

Naturalizing bodies and places: Tourism Media Campaigns and Heterosexualities in Costa Rica and New Zealand

Drawing on feminist, queer and poststructuralist theories of sexuality this article contributes to the field of tourism branding. Research findings on tourism media campaigns-New Zealand’s ‘100% Pure campaign’, and Costa Rica’s ‘No Artificial Ingredients’—illustrate how places and bodies are co-constructed and heterosexualized. We argue that both campaigns employ familiar landscape tropes of ‘nature’, ‘pureness’, ‘wilderness’, and ‘escape’, which discursively construct places and bodies as ‘natural’, ‘exotic’, and ‘romantic’. We draw on ethnographic and interview data to consider the lived experiences of these discourses for tourists and tourism businesses. By paying attention to the sexualized representations made and remade through tourism media campaigns the article challenges hegemonic conceptualizations of sexualities and offers an exciting future research agenda for tourism studies.     

The new public management and the UK Police Service

This article explores the impact of the introduction of the New Public Management (NPM) within the UK Police Service since the mid-1990s. A specific focus upon individual performance management (one of the central features of NPM) is examined from the perspective of the police sergeant who has primary responsibility for managing performance and ultimately the delivery of policing services within one of the UK's ‘essential’ public services. After a discussion of the literature on individual performance management within the context of the NPM, the article identifies four major research questions relating to: the job role demands of performance management; access to valid and reliable performance management information; the capacity to provide follow-up development and support; and the wider integration of performance management with organization strategy and service objectives. After reporting on interview data collected from role sets in which the sergeant is a focal member, the article concludes with a discussion of the constraints upon effective performance management within the NPM.     

The Outlook for European Grocery Retailing: Competition and Format Development

This article analyses retail trends in the main European countries, and particularly format evolution and competition amongst retailing firms. On the basis of the existence of European retailing landscapes that are sometimes similar without ever being identical, the article analyses the impact of the main factors of change on different national markets. Whilst retail internationalisation and new entrants, commercial policy, legislative environments, technological innovations, consumers and buying behaviour will have a convergence effect on different countries' retail structures, substantial differences will still exist. European retailing in the coming years will probably be characterized by increasingly less marked differences between countries than one finds today, but market segmentation, variety and differentiation of retailing formats and brand names will be stronger within each country.

Demand for Customized Products, Production Flexibility, and Price Competition

We examine markets where, in addition to production of standard (core) products, mass customization is technologically feasible. We compare a setting where a monopolist provides both standard and custom goods to a setting where an entrant joins the custom market and find customers' tastes affect the social desirability of entry. The entrant is unconcerned about the impact of its custom production on the incumbent's core product market and in some cases may supply more custom products than is socially desirable. Entry enhances (reduces) social welfare if consumers' core valuations are positively (negatively) related to their value added for customization.
