Does innovative city pilot policy promote urban green growth in China?An analysis of green total factor productivity,2005-2020

The innovative city pilot policy(ICPP)is an essential manifestation of China’s construction of an innovative and green-driven development country.We incorporated urban green total factor productivity(GTFP)growth into the evaluation of ICPP.Based on the panel data of 223 cities in China from 2005 to 2020,we used the difference-in-differences model to empirically assess the influence and mechanism of the ICPP on urban GTFP growth.The main results show that(i)The ICPP has maintained an effectively fluctuating promotion on urban GTFP growth,mainly manifested in the urban green technological progress improvement.(ii)The ICPP has urban heterogeneity in promoting GTFP growth in pilot cities,mainly affecting key cities such as provincial capitals.(iii)The interaction between the agglomeration of producer services and the ICPP inhibits GTFP growth in pilot cities.

Innovative Mode and Application of Flipped Classroom in City Design Course

The city planning quick topic design is a part of the city design course in many urban planning colleges.It can help stimulate the students’off-handed creativity and image expression ability.So it is necessary to explore the teaching mode which can adapt to it and stimulate students’learning enthusiasm and creative ability.In the context of promoting the"classroom revolution"of higher education in China,the flipped classroom has received widespread attention in the higher education community.Based on this,after three years of teaching practice,the author adaptively adjusted and innovatively modified the basic model of flip classroom in the quick topic design teaching of the city design course,and has found a variant model applicable to this course,namely OCTIAS(objective-case exploration-trial and error-instructional video-activities-summary and promotion).Firstly,insert two sections before the video learning,including"case travel exploration"and"trial and error(in order to accumulate beneficial failures)".Secondly,in the classroom activities,sort out the problems reflected by the students,and organize the students to make self-evaluation,mutual evaluation and revise the trial and error plan before the class.Finally,think about the problems that may occur in the cities in the future and their spatial organization responses.The practice showed that compared with the traditional teaching mode,the OCTIAS model could make the city design course more interesting,and help the students to improve in the solidity of theoretical knowledge learning,the flexibility of practical operation,the initiative to think about realistic problems,and the ability of critical thinking and expression.

Drivers of Innovative Urban and Peri-Urban Agriculture in Bamenda City, Cameroon

Urban and peri-urban agriculture (UPA) is gaining increasing importance in developing countries, due to rapid urbanization and rising rural-to-urban migration which has led to an increase in the population of the urban poor in Cameroon. It has been estimated that at least 70% of the total population of Cameroon will be living in urban areas by 2060. Urban and peri-urban agriculture (UPA) has become an important source of livelihood and survival, especially amongst the urban poor but is not adequately recognized and supported by the government of Cameroon and organizations. Recent innovations in UPA have created new opportunities for social, economic, and environmental sustainability of urban areas, hence possible policy formulation in UPA. Therefore, this study was conducted with the main objective of determining the drivers of innovative urban and peri-urban agriculture in Bamenda City, Cameroon. Methodologically, the study employed probit model, using primary data collected from a sample of 402 UPA farmers through the cluster, simple random, and snowball sampling techniques. The results revealed that access to extension services is a major driver of innovative UPA in Bamenda City and is statistically significant at 1%. Other factors such as employment status (full time), age group (26 to 50 years), and gender, were also seen to have a significant positive influence on innovative UPA while the level of education (secondary) had a negative influence on innovative UPA and was statistically significant at 5%. Limited capital, limited knowledge, and financial constraints were identified as the major challenges hindering the practice of innovative urban and peri-urban agriculture in Bamenda City. The study recommends that the government and non-governmental organizations should increase the quality and quantity of extension service delivery to urban and peri-urban farmers, and more recognition and support should be offered to them to help overcome the challenges faced.

An Innovative City： Impact of Innovations on City Development

The process of innovative development is stimulated by cities as centers of accumulated （regional） growth and innovative enterprises as elements of urban space. Cities stimulate innovations by creating a specific demand for innovations and innovative products as well as specific incentives such as preferable conditions for creation, accumulation, usage, and exchange of knowledge and information. Diffusion of ideas has an impact on changes in environment resulting in increase in dynamics of innovation, which means possibilities of innovative development for local firms. The paper highlights the idea of an innovative city with respect to the impact of innovations on city development. The concept of an innovative city is not clearly defined because the interpretation of innovation is differentiated and ambiguous except for common denominator of the novelty. The paper underlines the role of city＇s environment for innovations＇ creation acting as an incubator for clusters of firms, particularly those engaged in the process of high-tech involvement （technology parks）. The option of an innovative city approach presented here is the author＇s view on an innovative city＇s growth and it is based on the role of synergic interaction between innovative firms as elements of a city space and an innovative city itself.

A Cognitive Approach to the Formalization of City and County Names in China’s Hunan Province

There were mainly six types of formalization models found in the study for 95 city and county names in China’s Hunan province,namely,the environment in a place for the place,the wish of the nomenclator for the place,the relative position of a place for the place,the resident for the place,the legend for the place,and the function of a place for the place.In the six formalization models,environment in a place for the place was the most in number,forging 47 names.Besides,the wish of the nomenclator for the place and the relative position of a place for the place came the second,taking 20 names respectively.The cognitive operation participating in the formalization was primarily single metonymy with only a few complex metonymies.Metaphtonymy could be only noted in the model of the wish of the nomenclator for the place.It was notable that single metaphor was missing in the cognitive operations.

The Differences between County,County-level City and Municipal District in the System of Administrative Divisions in China

Administrative division is an important means of political power reorganization and management,resource integration and optimal allocation,which profoundly shapes the spatial layout of urban development in China.To clarify and compare differences between counties,county-level cities and municipal districts is the primary premise for the study of administrative division and urban development.This paper analyzes the institutional differences between counties and county-level cities,as well as counties,county-level cities and municipal districts,from the aspects of organizational structure,urban construction planning,land management,finance,taxation and public services.The research shows that the establishment of counties,county-level cities and municipal districts adapt to different levels and stages of economic and social development,and the conversion from county to county-level city and the conversion from county(or county-level city)to municipal district are both important transformation ways to change their administrative systems,which has different management system and operation pattern.At the same time,the transformation of county-level administrative region is also a“double-edged sword”,we should think about the administrative system as a whole to decide whether it should be adjusted,and effectively respond to the actual needs of local economic and social development.

Do smart city policies improve energy efficiency?Evidence from China

To address air pollution and offer a convenient and comfortable living environment,the Chinese government launched a smart city pilot(SCP)project in 2012,accompanied by a comprehensive set of environmental and energy-related laws and regulations.Although academic interest in smart cities has surged,there remains a notable gap in empirical research exploring the economic,environmental,and energy effects of such initiatives.Taking 232 prefecture-level cities from 2003 to 2017 as research subjects,this study measures energy effi‐ciency by using energy consumption per unit of GDP and adopts a difference-in-differences(DID)analysis to investigate the impact of SCPs on energy efficiency.The empirical results indicate that SCPs improved energy efficiency by promoting urban technological innovation capabilities and green total factor productivity,and this effect was more pronounced in cities that were more dependent on traditional fossil fuel energy sources and had more developed fiscal and financial levels.Studying the impact of smart city construction on energy utilization efficiency in developing countries,such as China,is not only significantly enlightening for China’s green and low-carbon transition but also provides reference opinions for constructing smart cities and the path to enhancing energy efficiency in other developing countries.The findings provide valuable insights into the global development of smart cities,urban sustainability,and high-quality economic growth.
