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. [ABSTRACT FROM AUTHOR]

This paper uses China's provincial border counties as samples to explore the role played by administrative boundaries in uneven regional economic development. The results indicate that the gap between provincial border counties and other regions is increasing and that economic diffusion to provincial border counties from developed regions is extremely weak. Moreover, provincial border counties have become economically backward. A regression analysis model that includes certain novel factors that are likely to influence economic growth confirms the significant effects of government intervention and administrative boundaries on economic growth in provincial border counties. This paper concludes that administrative boundaries' effects should be nullified by limiting preferential development policies and implementing policies that instead help provincial border counties engage in sustainable development.

There is mounting theoretical and empirical research that explains the reasons for the rapid expansion of China's export trade, but they mostly ignore the effects of cultural differences. To fill this gap, this paper provides an empirical investigation of how cultural diversity affects the sustainable development of trade, which is defined as the goal of maintaining certain volume of trade and making trade growth sustainable. The findings are as follows. (1) Cultural diversity can significantly promote the sustainable development of trade. (2) Entrepreneurship is the possible channel wherein cultural diversity affects the sustainable development of trade, including innovation entrepreneurship and business entrepreneurship. (3) Further studies demonstrate that economic openness has a significant moderating effect on the relationship between cultural diversity and the sustainable development of trade. That is, the higher the level of openness of a city, the stronger the promotion of cultural diversity to the sustainable development of trade. This study not only deepens understanding on the relationship between culture and trade but also provides important policy implications for many countries that have high migration rates.

As economic growth centres, the Southeast Asian cities feature high population pressure, unsustainable land use, environmental degradation, and large ecological footprints. It is difficult to manage environmental health and basic services for urban dwellers, and ensure optimum flow of ecosystem services in the context of rapid, unplanned, and haphazard urbanization. These challenges are particularly multifaceted in the developing countries of Southeast Asian region. This study, based on secondary sources, adopted multidisciplinary lenses, such as geographical information systems, socio‐economic perspective, and sustainability science to examine the population situation, land use change pattern, and drivers of environmental degradation in the Southeast Asian cities as well as the Dhaka megacity, and brought forth a fresh perspective to look into contemporary urban ecosystems, population dynamics, environmental health, and sustainability. It also focused on identifying the commonalities among the cities under study to create a common understanding towards promoting collaborative urban development. This study shows that the urbanization process in the Southeast Asia region is taking place mostly in an unplanned and haphazard manner. With little concern for nature, life‐supporting ecological systems, and the environment, urban spatial growth continues unabated. The data surveyed and discussed in this paper shows that the current style of urbanization in Southeast Asia can best be called unsustainable. The findings also suggest that the general wellbeing and welfare of the current and future generations in Southeast Asian cities as well as in Dhaka is at risk. The paper recommends concerted efforts towards making the urbanization process sustainable, including better urban planning, policymaking, and international and regional cooperation.

In recent years, the endogenous development ( ED) approach has gained influence within the rhetoric of European rural development policies ( RP). This paper provides a fundamental critique of the approach and shows that neither the economic elements of RP in general nor ED in particular are targeted towards the specific economic needs and capabilities of rural areas. The second part of this paper consists of the search for possible alternative concepts for a more targeted and effective RP. Based on a synopsis of existing theories, an integrated approach is proposed that builds upon the different coordination mechanisms for economic activity suggested by different theories. The new, integrated perspective enables an economic characterisation of rural areas and indicates that the successful support of local coordination of economic activity is determined by specific local conditions. It also makes evident that localised approaches usually cannot compensate rural areas for the lack of agglomeration advantages. Therefore, programmes for the economic development of rural areas which support the local coordination of economic activity remain a second-best policy. As such, they do not free the state from policies of spatial redistribution if the political aim is the creation of comparable living conditions. [ABSTRACT FROM AUTHOR]

Improving green development efficiency is urgently required, yet challenging, since it comprehensively reflects the bidirectional evolutionary relationship between regional development and resource and environmental consumption. The issue of regional green development efficiency has become a key topic; however, where the increase in efficiency originates and its spatial spillover effect remains unclear to date. Therefore, the spatial spillover effect of the green development efficiency of Shandong Province was quantified through the slack variable (SBM)‐Undesirable and Spatial Durbin model. The green development efficiency showed clear spatial differentiation in Shandong Province. This was more obvious than the polarized development trend of the provincial capital circle that has Jinan at its core and the eastern coastal region with Qingdao at its core. Green development efficiency has a significant spatial spillover effect. The regression coefficient of the direct effect of the economic development level is positive. The regression coefficient of the indirect effect of the marketization level and government financial support level is negative. Science and technology played a positive role in the promotion of the green development efficiency of local and neighboring cities. This study contributes empirical evidence to the green development efficiency associated with regional development and resource and environment consumption of Shandong Province. [ABSTRACT FROM AUTHOR]
