The Geography of Innovation in China and India

The BRICS countries in general, and China and India in particular, are now widely regarded as the areas of the world likely to challenge the economic leadership of the United States (US) and the European Union (EU). A large part of this challenge will come from rapid technological catch‐up by China and India. Yet, despite a recent rise in interest, there is limited knowledge about how and where innovation takes place in these two leading emerging countries and to what extent the Chinese and Indian territorial systems of innovation differ from those in the EU or the US. In this article we explore the geography of innovation in China and India, concentrating on understanding key territorial‐level innovation trends by country, region and technology field, using the US and the EU as benchmarks. We find significant contrasts between the geography of innovation in China and India and that of the US and the EU. First, the degree of concentration of innovative activities in both countries is extremely high. Levels of agglomeration of innovation in the coastal provinces of China, as well as in Delhi and the South of India, significantly exceed the levels of agglomeration found in the USA and the EU. Secondly, China has witnessed a more rapid increase in the degree of concentration of innovation than India. We posit that the differences in the geography of innovation between, on the one hand, China and India and, on the other hand, between these countries and the developed world are rooted in different institutional settings, different systems of innovation and different national innovation strategies.     

WHAT'S TO KNOW ABOUT THE CREDIBILITY OF EMPIRICAL ECONOMICS?

The scientific credibility of economics is itself a scientific question that can be addressed with both theoretical speculations and empirical data. In this review, we examine the major parameters that are expected to affect the credibility of empirical economics: sample size, magnitude of pursued effects, number and pre‐selection of tested relationships, flexibility and lack of standardization in designs, definitions, outcomes and analyses, financial and other interests and prejudices, and the multiplicity and fragmentation of efforts. We summarize and discuss the empirical evidence on the lack of a robust reproducibility culture in economics and business research, the prevalence of potential publication and other selective reporting biases, and other failures and biases in the market of scientific information. Overall, the credibility of the economics literature is likely to be modest or even low.     

Towards a Theory of Serendipity: A Systematic Review and Conceptualization

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.     

Engineering Cities: Mediating Materialities,Infrastructural Imaginaries and Shifting Regimes of Urban Expertise

This symposium opens up new critical insights and analytical perspectives into the relationships between power, politics, materiality and urban engineering. In so doing it demonstrates the central role of engineers in the production and negotiation of everyday life in the city. In contrast to the technocratic exercise engineering often professes to be, the contributors to this symposium argue that the assembling and choreography of cities through the myriad techniques, routines, standards and visions of engineers is inextricably bound up with broader socio‐cultural, material and political urban dynamics and processes. This necessitates investigating the multiple and competing social imaginations, forms of knowledge and regimes of expertise associated with urban engineering. The symposium's five articles, straddling disciplinary backgrounds in geography, anthropology, engineering and history, focus analytical and empirical attention on the figure of the engineer and on the work of engineering in the cities of Paris, Mumbai, Singapore and London. Engineering, we suggest, is a diagnostic for probing the shifting forms of mediation that animate and inhabit contemporary dynamics of urban change. The symposium thus opens up a new avenue for cross‐disciplinary and transregional research for urban studies while also suggesting innovative ways of conceptualizing urban transformation and contestation.

Supply Chain Strategies in the UK Fashion Industry—The Rhetoric of Partnership and Realities of Power

This paper focuses on the fashion industry, one characterised by issues such as dramatic shifts in the scale and power of major retail buyers in the market, the advent of retailer own brands, and the nature of sourcing and supply chain decisions, issues that are increasingly global in nature. The aim of this research is to explore the nature of relationships between UK high street multiple fashion retailers and their contracted suppliers, many of whom are entrepreneurial firms by most definitions of the term. Four core themes emerge from the literature and provide a framework for the research, namely, power, process, partnership, and people. The research approach was qualitative, and conducted over a period of twelve months. The paper ends with an agenda for future research.

Bourdieu Comes to Town: Pertinence,Principles, Applications

This article frames the themes of the two‐part Interventions section ‘Bourdieu Comes to Town’. I first establish the pertinence of Bourdieu's sociology for students of the city by revisiting his youthful work on power, space, and the diffusion of urban forms in provincial Béarn and colonial Algeria. In both cases, urbanization is the key vector of transformation, and the city, town, or camp the site anchoring the forces dissolving the social fabric of the French countryside and overturning French imperialism in North Africa. These early studies establish that all social and mental structures have spatial correlates and conditions of possibility; that social distance and power relations are both expressed in and reinforced by spatial distance; and that propinquity to the center of accumulation of capital (economic, military, or cultural) is a key determinant of the force and velocity of social change. Next, I discuss four principles that undergird Bourdieu's investigations and can profitably drive urban inquiry: the Bachelardian moment of epistemological rupture, the Weberian invitation to historicize the agent (habitus), the world (social space) and the categories of the analyst (epistemic reflexivity); the Leibnizian‐Durkheimian imperative to deploy the topological mode of reasoning; and Cassirer's command to heed the constitutive efficacy of symbolic structures. The plasticity and productivity of his concepts suggest that Bourdieu can not only energize urban inquiry but also merge it into a broader analytic of the trialectic of symbolic division, social space, and the built environment. This paves a pathway for reconceptualizing the urban as the domain of accumulation, differentiation and contestation of manifold forms of capital, which makes the city a central ground, product, and prize of historical struggles.
