China's urbanization is a traditional development way of high energy consumption, low efficiency and extensive type. The resulting ecological environment damage and other problems seriously restrict the healthy and sustainable development of the city. Based on this, aiming at the complexity of the system, the multi-objective classification matrix method of fuzzy decision was selected, and the life cycle assessment model of the urban innovation ecosystem under the background of new urbanization in China was constructed. The research on the innovative ecological system planning of a heavy industrial city was carried out, and the wall was greening in the top space of the building. In the town planning, wind energy, solar power system, green corridor and ground floor were designed. Practice has proved that introducing innovative ecosystem into urbanization has played an important role in purifying urban air, increasing urban greening, improving energy structure and air pollution.

This paper aims to analyze the spatiotemporal heterogeneity of regional total factor productivity (TFP) growth and explores how haze pollution and different levels of new-type urbanization affect China’s economic growth.

This paper constructs an index for evaluating the TFP growth of China’s 31 provinces by integrating slack-based measures and the Global Malmquist (GM) productivity index. Meanwhile, the panel threshold estimation method is used to examine the complex relationships among haze pollution, new-type urbanization and TFP growth.

The results reflect conspicuous spatiotemporal heterogeneity in TFP growth in China. Interestingly, the influence of haze pollution on TFP growth is limited by the “critical mass” of new-type urbanization in China. When new-type urbanization does not cross the first threshold, haze pollution has a negative but non-significant effect on TFP growth. When new-type urbanization crosses the first threshold but not the second, haze pollution has a significant positive impact on TFP growth. When new-type urbanization crosses the second threshold, haze pollution significantly and positively affects TFP growth with the strongest positive effect.

This study innovates by combining haze pollution and TFP growth and proposing an integrated framework from the perspective of new-type urbanization, providing insight into how different degrees of new-type urbanization impact the mechanism between haze pollution and TFP growth. Using panel data in China and emphasizing green development, a sustainable economy and new-type urbanization, this study contributes to the current studies on haze pollution and economic development based on developed countries.

With the advancement of new-types of urbanization, our country needs to construct reasonable structures of the resource-based central city and sub-central city in the regions, to transform the mode of the development of the city, to achieve the coordinated and the sustainable in resources, to avoid the resources of waste and to build the green, low carbon, agglomeration and sustainable new towns. This paper does the analysis of SWOT by putting forward a specific example which establishes Handan as the central city and Wu’an and Feixiang act as the sub-central cities to explore the advantages of choosing resource-based city as a central city, which gives the support in theory and practice for realizing the winwin situation and maximization of interests in the regions.

The quest for economic development has brought adverse effects on the environment through the release of greenhouse gases, such as carbon dioxide (CO₂₎. This will counter the efforts to achieve the Sustainable Development Goals (SDGs) by 2030. This study, therefore, investigates the effect of electricity consumption and urbanization on CO₂ emissions in Ghana. Electricity consumption and urbanization are among the factors that can be used to reduce CO₂ emissions.

Following the STIRPAT framework with the Hansen (2000) least squares threshold estimation strategy, the study employed annual time series data from 1971 to 2019.

The study revealed a single threshold effect of both electricity consumption and urbanization on CO₂ emissions. Electricity consumption intensity reduces CO₂ emission when electricity consumption is below the threshold (6287GWh) but increases when consumption passes the threshold. However, urbanization exerts a positive influence on CO₂ emissions regardless the level of urbanization (either before or after the threshold point). Again, the empirical results revealed that the urbanization threshold moderates the effect of electricity consumption on CO₂ emissions.

Policymakers have to consider redesigning the current urbanization mode to include some new-type urbanization elements.

The threshold effect of electricity consumption and urbanization on CO₂ emissions in Ghana is examined using the Hansen (2000) least square method.

To promote the effective allocation of public sports venues in the county and promote the construction of new urbanization, the allocation of public stadiums in the county was studied under the background of new urbanization. Interviews and literature research methods were adopted. The differences between the new urbanization and the traditional urbanization of the county's public stadiums were discussed. Under the background of new urbanization, the status quo of the allocation of public stadiums in China's counties was studied. Under the background of new urbanization, the problems and influencing factors of the allocation of public stadiums in China's counties were analyzed. The corresponding proposal was put forward. The results showed that the number of county venues in China was greatly improved, but the total amount was still insufficient. The configuration structure was improved, but the structural imbalance was still significant. The way of configuration was innovative, but the government dominated the main position. The configuration policy was constantly improving. The legalization was not perfect. Therefore, the balance between supply and demand, the balance of urban and rural settings, the optimization of public sports venues, and the establishment of public stadiums under new urbanization are important. This will help to promote the study of the allocation of public sports venues in China's counties under the background of new urbanization.

Over the past 20 years, China's infrastructure has developed at an extraordinary speed. The current literature mainly focuses on the effects of political incentives on the infrastructure. However, this paper indicates that the structural change of China's land regime is an important clue and that the supernormal development of China's infrastructure is an explicable result for that.

This paper theoretically proves that in a politically centralized and economically decentralized economic entity with a public land-ownership regime, the self-financing mechanism formed by local officials through regulation of the land-grant price is the primary factor that influences the optimal supply volume of infrastructure in a region, in addition to political and economic incentives, and whether the self-financing mechanism can be formed or not depends on the structure of a country's land regime, which can help to explain the difference between the development of infrastructure in China and that in other developing countries from a theoretical angle.

The paper suggests that the mode is facing an important transformation toward land reform and new-type urbanization construction, and the replication and promotion of China's experience in infrastructure construction are of further significance under the Belt and Road Initiative as it provides a method for helping developing countries to eliminate infrastructure bottlenecks.

Through the test of multinational panel data, the paper indicates that the structural change of China's land regime around 1990 had an overall effect on the supernormal development of infrastructure in China. The paper indicates that the “land-based development mode” of China's infrastructure indeed contributed to the supernormal development of infrastructure in China, but there are still some shortcomings in this mode.

With the accelerating process of urbanization, the greening areas in high density cities are becoming less and less, and the aerial greening provides a possible way for the update of the urban building headspace greening. Based on this, the application of aerial greening in the urban headspace was studied. Starting from the plant, water, landscape sketch, pavement and other construction elements, the ecological art planning and design of the urban building headspace was studied. Then, the transformation of an old factory was studied, and the rain-flood gardens and infiltration floors linked to biological corridors were introduced in the high flood risk areas. In the building headspace, a rainwater harvesting system and an air garden were designed, and the ecological planning of aerial walkway was carried out to the front abandoned viaduct. The practice proves that the introduction of ecological science and technology and art culture in the urban headspace plays an important role in purifying urban air and increasing urban greening.

This paper aims to apply a comprehensive Liveability Cities index to rank the liveability of 100 cities in the Greater China Region. Against the backdrop of the ongoing trend of rapid and extensive urbanisation observed in China, “liveability” is being given an increasingly higher priority by the Chinese government. However, there has been no attempt to empirically measure this concept and to examine its nexus to the narrower concept of competitiveness.

The index is based on 96 indicators across five environments, namely, economic vibrancy and competitiveness; environmental friendliness and sustainability; domestic security and stability; socio-cultural conditions; and political governance.

The empirical results show that Hong Kong, Macau and cities in Taiwan generally perform well in overall liveability rankings, while first-tier cities in mainland China (Beijing, Shanghai, Guangzhou and Shenzhen) do not find a place among the top ranks.

The rankings and simulation exercise aim to provide Chinese policy makers with a framework to assess the liveability of China’s cities and suggests indicative policy suggestions that can be taken to improve overall liveability.

The purpose of this paper is to examine the impacts of rural–urban migration on agricultural (labor) productivity in China.

This paper closely follows the framework of Rozelle et al. (1999), Taylor et al. (2003) and Atamanov and Van den Berg (2012)—new economics of labor migration—to demonstrate the heterogeneous effects of migration on agricultural productivity, using simultaneous equations extended by an interaction term of off-farm income and household wealth.

The results empirically verify two key theoretical predictions: the loss of labor available for agricultural activities decreases rice yield per worker per day, and the off-farm income that may relax liquidity constraints has a positive offsetting effect, which becomes weaker with increasing household wealth. The final calculation based on these two contradictory influences indicates that the lost-labor effect dominates across all levels of household wealth, resulting in a negative net impact of rural–urban migration on agricultural productivity. The key results are shown to hold for land productivity as well.

To the best of the author’s knowledge, it is the first paper to examine the impacts of rural–urban migration on labor productivity and the heterogeneity across households with different levels of wealth. A major policy issue facing national leaders is whether the massive and ongoing outflow of labor will be a threat to China’s rural development and its food security in the future. This paper provides insightful ideas in a different way.
