The comparative study of China's mega‐city regions: A perspective of competitiveness

Mega‐city regions (MCRs) have emerged as the main spatial form of China's new urbanization strategy and become the basic spatial units participating in global and regional competition. However, MCRs are not equally capable of boosting regional economic development due to their different levels of development. Therefore, this paper adopts the concept of competitiveness as both a theoretical framework and an empirical model to evaluate the development status of China's MCRs. Based on a review of the existing literature, this paper proposes a multi‐tier evaluation system to calculate the competitiveness of 13 MCRs. The chosen indicators come from the six perspectives of economic development, human resources, infrastructural accessibility, integration into the global economy, capacity for scientific and technological innovation, and sustainable development. The results show that there are great disparities and regional inequalities in competitiveness across different MCRs. The Yangtze River Delta, Pearl River Delta, and Beijing–Tianjin–Tangshan MCRs are the first‐tier MCRs with the highest levels of development and have significant global influence as well. Chengdu–Chongqing, Shandong Peninsula, South‐central Liaoning, and Wuhan belong to the second‐tier of MCRs that show partial advantages and have significant regional influence. The remaining regions belong to the third‐ or fourth‐tier of MCRs that have relatively weak competitiveness. The competitiveness of MCRs largely depends on the concentration of core elements in core cities.     

The peri‐urbanisation of Shanghai: Planning,growth pattern and sustainable development

Abstract: With the increase of global integration, the peri‐urban area (PUA) of megacities in Asia has become a favourite destination for foreign direct investment (FDI). This paper uses the PUA of Shanghai as a case study to investigate the impact of global forces on the urban expansion of the city, and the link between urban growth and sustainable development in this mega‐urban context. Shanghai has grown impressively during the past two decades in terms of economic and physical transformation. Much of this transformation has rested on the unbridled exploitation of land and other environmental resources in its peri‐urban area. This is characterised by the designation of development zones and the concentration of manufacturing FDI, resulting in dispersed growth and environmental degradation. The disruption of the physical environment, combined with the concentration of the urban poor in these areas (in particular ‘temporary migrants’), has turned the PUA into a potential crisis point threatening the social and economic development of the city.     

Quality of Life and the Migration of the College‐Educated: A Life‐Course Approach

ABSTRACT This paper examines how the college‐educated population—segmented into selective demographic groups, from young adults to the elderly—differentially values quality‐of‐life (QOL) indicators of metropolitan areas in the United States. Using data from the 2000 Census and the 1997 Places Rated Almanac, out‐migration patterns are shown to depend jointly upon stage in the life course, the spatial‐demographic setting, and QOL characteristics. An abundance of cultural and recreational amenities lowers out‐migration rates of young college‐educated. For the older college‐educated population, the revealed preferences shift toward concerns for safety and a strong preference for milder climates. The study also finds significantly lower out‐migration rates for metropolitan areas with growing human capital. In light of shifting age distributions and rising educational attainment levels, the results have important implications for the emergence of new migration patterns and the concentration of human capital.     

Low‐Income Dynamics in Canadian Communities: A Place‐Based Approach

ABSTRACT Canadian poverty rates have persisted at disappointingly high levels despite almost 15 years of continuous economic growth. The problem is exacerbated by some communities and neighborhoods having exceedingly high poverty, including very high rates for vulnerable demographic groups, such as aboriginals and recent immigrants. We investigate low‐income rates (poverty rates) for 2,400 Canadian “communities” over the 1981–2001 period. By focusing on communities, we fill a void in the related Canadian literature, which tends to focus on individuals, case studies, or more aggregate measures, such as provinces. Our approach allows us to assess the role of place‐based policies. Particular attention is given to communities with differing shares of aboriginal Canadians and recent immigrants. One novel feature is our analysis of both “short‐term” and “long‐term” causes of differential community poverty rates. The results suggest that community low‐income rates are more affected by initial economic conditions in the short term, with certain demographic factors becoming relatively more important in the long run.     

The structure and proximity mechanism of formal innovation networks: Evidence from Shanghai high‐tech ITISAs

The discussion on innovation networks of patents or papers has attracted many economic geographers; however, the Industrial Technology Innovation Strategy Alliance (ITISA) has been ignored, although it is also an important innovation form of firms, and the formation mechanism of alliance innovation networks is unclear. This study is based on the data of Shanghai high‐tech ITISAs between 2010 and 2015, and employs the methods of social networks and negative binomial regression to analyse the actor structure, spatial structure, and proximity mechanism of innovation networks of Shanghai high‐tech ITISAs. Results highlight the following: (a) Firms comprise the largest number of actors in alliance innovation networks, and universities, research institutions, and industry associations also play some roles. (b) The local and rooted characteristics of the innovation networks of ITISAs are obvious. The spatial distribution of innovation partners is mainly in Shanghai, and a few innovation actors are located in neighbouring cities, such as Suzhou, Hangzhou, and Ningbo in the Yangtze River Delta Urban Agglomeration. (c) Proximity significantly promotes the formation of innovation networks in an ITISA and contributes to the improvement of innovation ability, and organizational proximity plays a greater role than geographical proximity or cognitive proximity.     

Living in Two Worlds: A Review of Home‐to‐Work Decisions

ABSTRACT This paper discusses various aspects of the economic analysis of commuting behavior. It starts with a review of two difficulties associated with urban economics models: the empirically falsified prediction of the relation between commuting time and income, and the presence of substantial excess commuting. Notwithstanding these anomalies, research that focuses directly on the value of travel time provides evidence that there is substantial resistance against commuting among large groups of workers. However, commuting costs are just one among many other explanatory variables for actual commuting behavior, and commuting itself has become much less onerous over time. This suggests that commuting costs play a much more limited role than has been assumed in the past. On the other hand, empirical evidence suggests that space is more important than one would be inclined to think on the basis of the considerations just given. These empirical regularities suggest that other space‐related aspects of the functioning of urban labor and housing markets are more important than was previously thought.     

Poverty and livelihoods after full‐time farming: A South‐East Asian view

Abstract: Drawing on Harold Brookfield's seminal interventions on intensification and disintensification in tropical agriculture, the paper argues that a de‐linking of poverty and livelihoods in rural areas from farming and agricultural resources is occurring in rural South‐East Asia. This is often driven as much by changes in lifestyles and life views than by economic and environmental imperatives. The paper proposes that farming is in the process of losing its resonance and significance for the rural poor. Emerging patterns of change in the South‐East Asian countryside are used to construct a generalised framework of agrarian transition where the current trend towards pluriactivity is likely to be replaced by a mixed landscape of agrarian entrepreneurs, neopeasants and remnant smallholders. The paper concludes by reflecting on the implications of this trajectory for understanding poverty and pro‐poor interventions in the countryside.     

From free to forced adaptation: A political ecology of the ‘state‐society‐flood’ nexus in the Vietnamese Mekong Delta

This paper investigates the adaptation processes with reference to the narrative analysis of human–environment interactions in the Vietnamese Mekong Delta. From the political ecology perspective, it focuses on the discourses of the power relationships embedded within the ‘state‐society‐flood’ nexus over the course of its ‘opening‐up and closing‐off’ processes (e.g. excavating large‐scale canals for human settlements and agricultural expansion (opening‐up) and human interventions into natural systems through water control structures (closing‐off)). Drawing on empirical data gathered from 33 interviews and nine focus group discussions in three study areas and relevant literature, the paper argues that human interactions with the flood environments are intertwined with adjustments of adaptation patterns as evidenced through three periods: free adaptation (pre‐1975), transitional adaptation (1976–2010) and forced adaptation (after 2010). These processes have witnessed a gradual power shift in the ‘state‐society’ relations in manipulating floods, which moves from the top‐down towards a more collaborative fashion. By unravelling the political ecology of the ‘state‐society‐flood’ nexus, this paper exhibits the skewed development in the delta, which is largely bound to short‐term development planning to prioritise local socio‐economic and political objectives. The paper contributes important policy implications for achieving socially just and environmentally sustainable development in the delta.     

Showcasing the sovereignty of non‐self‐governing islands: New Caledonia

Since 1983, no non‐self‐governing island connected to a (neo‐) colonial European or American metropole has acquired full Westphalian sovereignty and these islands continue to operate within constitutional frameworks that connect them to these metropoles. Large majorities in referendums on several of these islands have rejected full sovereignty. This paper opens with a review of the essential elements of the concept of sovereignty in a historical and global context, before studying how sovereignty is unfolding in new forms in non‐self‐governing islands in the Pacific and the Caribbean. As a case study, an analysis is presented of how pro‐France (loyaliste) and pro‐independence (indépendantiste) parties in New Caledonia are negotiating sovereignty with France. Evidence is given of how these New Caledonian parties are creatively using classic Westphalian signifiers of sovereignty normally reserved for sovereign states such as flags, diplomatic representations and international treaties, while still negotiating New Caledonia's sovereignty with France. This suggests that in contrast to Westphalian sovereignty, a unique ‘Islandian’ concept of sovereignty is emerging. Islands that are not sovereign in a Westphalian sense can creatively disassemble and reassemble signifiers of Westphalian sovereignty to strengthen their continuous negotiations with their metropoles and their neighbours.     

A Simple Drought‐Sensitive Model for Leaf : Stem Partitioning of Wheat

We investigated the leaf : stem partitioning of winter wheat (Triticum aestivum L. varieties ‘Dekan’ and ‘Batis’) with and without drought influence. Irrigated and drought‐stressed winter wheat, grown in a rainout shelter in 2009/10 and 2013/14, were sampled during shoot elongation phase at the experimental Farm Hohenschulen located in Northern Germany. The data set contains leaf (DM_L) and stem dry masses (DM_S), as well as measured water contents for several soil layers. A reduced relative dry matter allocation to leaves was observed under drought stress. Our results clearly show that, if simulated leaf : stem partitioning is not sensitive to drought, this will cause a positive bias in simulated leaf and a negative bias in simulated stem dry matter under water‐limited conditions. This is in accordance with previous studies which revealed that crop simulators often overestimate the impact of drought on light‐use efficiency, whereas the consequences on leaf area development are underestimated. However, the drought stress‐induced shift in leaf : stem partitioning is yet not considered by most common wheat crop simulators. Our aim was to fill the gap in simulation of drought stress implications on leaf area development. A simple allometric model for leaf : stem partitioning () was parameterized. Starting from the allometric leaf : stem relationship observed under optimum water supply, a correction term was introduced, which allows to adapt the partitioning to drought stress conditions. The lg‐transformed root‐weighted soil water potential in the rooting zone (lgψ_root, lg(hPa)), calculated as a function of measured water contents and simulated root distribution, was used as a drought stress indicator. The linear correction term assumes an increase of the stem fraction, proportional to the difference between lgψ_root and a drought stress threshold (pF_crit, lg(hPa)). The analysis revealed that the shift in allometric partitioning towards stem fraction starts with lgψ_root greater than 1.92 [lg(hPa)]. The slope of the relative increase of dry matter allocated to the stem fraction was determined with 0.26 [lg(hPa)^?1]. Both parameters of the correction term were found to be highly significant. Implications for crop modelling are discussed.     

Foreign direct investment flows to Mexican states: A study of the automobile industry, 2004–2014

This study examines the subnational flow in foreign direct investment (FDI) to Mexican states, with a focus on the finished vehicle industry. Although prior studies have examined subnational FDI in Mexico, research on the automobile sector has been scant. Utilizing a framework associated with the theory of asset specificity, we examine the influence of human capital and labor conditions, infrastructure, subnational policies, and security. The study employs a data set on finished vehicle FDI across 31 states and the Federal district for the period of 2004–2014. We adopt a two‐part model. The first part, which includes all states and the Federal district, is estimated with pooled logistic and Firth logistic regressions. In the second part, we examine variation in levels of FDI among states selected for investment with pooled ordinary least squares with panel‐corrected and Driscoll Kraay standard errors. Labor conditions are significant for both state selection and levels of FDI, but education is influential only in the selection stage. In addition, states with trunk rail lines linked to the U.S. border are more likely to be selected and receive higher FDI. After controlling for these influences, murder and homicide rates, and state development have no significant effects.     

In situ off‐farm work in the transport industry among oil palm smallholders in Sabah: Negotiating the borders of licit and illegal activities

This paper examines the informal transport sector within the smallholder oil palm economies of Kinabatangan and Lahad Datu areas of eastern Sabah by looking at the metaphoric border that is constructed between licit and illegal activities that take place on roads. It describes the work of two groups of drivers, namely, those who are themselves smallholders who provide a crucial service to the community in getting their fresh fruit bunches to mills on time; and the piret (pirate) taxis who transport passengers including foreign nationals, some of whom are illegal workers. Many have been driving for some time, thereby challenging the notion about off‐farm work as providing a temporary safety net to smallholders. Drivers whose permits may be current may have used illegal means (such as meminggir – logging without licence), to accumulate the initial funds for acquiring their vehicles and necessary permits. Moreover, their clients are unconcerned about their ‘illegal’ status. Consequently, this paper maintains that there is no agreed‐upon norms about legality/illegality, and law enforcement being uneven, the zone in which drivers operate is a fluid one.     

Creating community‐based indicators of gender equity: A methodology

It appears that an almost unquestioned development pathway for achieving gender equity and women's empowerment has taken centre stage in mainstream development. This pathway focuses on economic outcomes that are assumed to be achieved by increasing women's access to material things, including cash income, loans, physical assets, and to markets. Gender equity indicators, which measure progress towards these outcomes, cannot escape reinforcing them. We argue that far from being neutral, indicators are embedded in political and ideological agendas that serve as guides to the appropriate conduct of those whose performance or behaviour is being measured. Drawing on participatory feminist, diverse economies and strengths based approaches, we outline a research methodology for developing community‐based indicators that recognises women's and men's participation and relationships in all spheres of life, including the ‘non‐economic’. If indicators are grounded in local meanings and realities, we propose that community members can use them to identify aspirational goals for gender equity, and measure progress towards these goals.     

Assessing the Potential for Zone‐Specific Management of Cereals in Low‐Rainfall South‐Eastern Australia: Combining On‐Farm Results and Simulation Analysis

In the low‐rainfall region of south‐eastern Australia, distinctive soil types reflecting the typical landscape of higher elevated dunes and swale zones at the bottom can be found within one field. Different soil characteristics cause consequently large variability in cropping productivity between soils and across seasons. To assess the possibilities for zone‐specific management, five farmer fields were zoned into a dune, mid‐slope and swale zone. For each site, zone yields were mapped over 2 years and soil properties were surveyed. This information was used to parameterize and validate the APSIM model for each zone. Field‐measured PAWC increased from the dune to the swale zone. On‐farm results and simulation analysis showed distinctive yield performance of the three designed zones. However, yield is not related to PAWC, it is rather a complex relationship between soil type, fertility and rainfall. While in high‐rainfall years, the swale zones yielded higher due to higher soil organic carbon content and less drainage losses, the dune zones performed better in the low‐rainfall years due to lower evaporation losses. This study emphasizes that in this specific environment where soil variation in texture and subsoil constraints strongly influence crop performance, mechanistic crop models and long‐term field observations are necessary for better understanding of zone‐specific performance, and simple linear relationships across years or sites are not useful.     

The Spatial Dimension of Trade‐ and FDI‐driven Productivity Growth in Chinese Provinces: A Global Cointegration Approach

This paper analyses the major determinants of long‐ and short‐run labour productivity evolution for Chinese provinces between 1978 and 2010. The role played by openness to trade and foreign direct investment (FDI) constitutes the main focus of this analysis. From a methodological perspective, our main contribution is the inclusion of spatial effects into a dynamic error correction modelling framework. The results show that, in addition to domestic factors such as investment intensity and infrastructure use, trade openness and inward FDI also exert a direct impact on labour productivity. Furthermore, the geographical environment has a strong indirect influence on productivity: The more a region is surrounded by high‐productive regions with good infrastructure and linkages to the world economy, the higher are its productivity level and growth rate. The magnitude of these impacts varies by spatial regime (coastal, interior provinces) and time period in focus. Especially in the recent past, trade and FDI activity appear to be increasingly important drivers of regional productivity evolution, both for coastal and interior regions. These findings have important policy implications: In order to fully exploit the benefits from such spillovers, coordinated industrial policies which foster regional complementarities and support the free movement of production factors across regional borders are crucial.     

Rethinking Technology‐Oriented Business Incubators: Developing a Robust Policy Instrument for Entrepreneurship,Innovation, and Regional Development?

ABSTRACT Today, technology‐oriented business incubators are a worldwide phenomenon, although empirical research evidence clearly suggests that they tend to fail in supporting entrepreneurship, innovation, and regional development and, therefore, do not fulfil their expected role as policy instrument. The paper focuses on this obvious antagonism. It deliberates upon political rationales, reviews evaluation literatures, and delineates suggestions for the future of the incubation industry. The main conclusion is that technology‐oriented business incubators should be run as private organisations without public funding.     

Changes in Hormonal Balance: A Possible Mechanism of Pre‐Sowing Chilling‐Induced Salt Tolerance in Spring Wheat

There is a lack of knowledge about factors contributing to the chilling‐induced alleviatory effects on growth of plants under salt stress. Thus, the primary objective of the study was to determine whether chilling‐induced changes in endogenous hormones, ionic partitioning within shoots and roots and/or gaseous exchange characteristics is involved in salt tolerance of two genetically diverses of wheat crops. For this purpose, the seeds of two spring wheat (Triticum aestivum) cultivars, MH‐97 (salt intolerant) and Inqlab‐91 (salt tolerant) were chilled at 3°C for 2 weeks. The chilled, hydroprimed and non‐primed (control) seeds of the two wheat cultivars were sown in both Petri dishes in a growth room and in the field after treatment with 15 dS m^?1 NaCl salinity. Chilling was very effective in increasing germination rate and subsequent growth when compared with hydropriming and control under salt stress. Results from field experiments clearly indicated the efficacy of chilling over hydropriming in improving shoot dry biomass and grain yield in either cultivar, particularly under salt stress. This increase in growth and yield was related to increased net photosynthetic rate, greater potential to uptake and accumulate the beneficial mineral elements (K⁺ and Ca²⁺) in the roots and reduced uptake and accumulation of toxic mineral element (Na⁺) in the shoots of both wheat cultivars when grown under salt stress. Salt‐stressed plants of both wheat cultivars raised from chilled seed had greater concentrations of indoleacetic acid, abscisic acid, salicylic acid and spermine when compared with hydropriming and control. Therefore, induction of salt tolerance by pre‐sowing chilling treatment in wheat could be attributed to its beneficial effects on ionic homeostasis and hormonal balance. The results presented are also helpful to understand the chilling‐induced cross adaptation of plants in natural environments. Moreover, efficacy of pre‐sowing chilling treatment over hydropriming suggested its commercial utilization as a low risk priming treatment for better wheat crop production under stressful environments.
