Abstract Over the years, much research has focused on industrial relocations between countries resulting from globalisation and modernisation. However, relocation decisions of individual firms within metropolitan areas remain an insufficiently studied aspect literature. This study aims to fill this gap by examining intentions locations high‐tech manufacturing at various stages development in Beijing firm life cycle perspective. The results show that larger with more employees higher property...

Continuous, smooth, and highly linear displacement output with centimeter-scale stroke nanometer-scale resolution is greatly attractive for an ultraprecision positioning system. On the foundation of piezoelectric actuation compliant mechanism, a novel piezomotor minimized backward nonlinear motion property designed. Specifically, driving unit capable <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex-math...

The rainy season is an important climate feature over Eastern China where anomaly in either its timing or length can lead to adverse economic and social consequences. Here, we illustrate that the records of daily precipitation description at Beijing Shanghai contained Memos-to-Emperor during Qing Dynasty provide a unique source extend information 1736. together with instrument measurements since 1875 both cities reveals significant inter-annual decadal variations beginning ending dates,...

Strategic emerging industries (SEIs) are an important industrial policy to promote innovation, develop advanced manufacturing, and upgrade the economy in China. The research explores impact of SEIs on urban economic growth mainland China, from agglomeration externalities network externalities. results show that have a significant growth, generally more than Although large‐scale listed enterprises city promotes too many large cluster, is, lack small medium‐sized supporting enterprises, will...

As a primary source of urban pollution, waste plants release toxic gases and polluted water that can cause great harm to human health contaminate resources. The adverse impact on environmental threaten the quality life surrounding residents which will be reflected in residential property values. In this study, we develop hedonic price model estimate externalities based panel dataset for real-estate transactions Beijing from 2011 2015. We apply fixed effects Heckman selection control omitted...

Industrial migration is a hot topic in economic geography. This study traces the migratory process of key high-tech enterprises Beijing during 2008–2016, revealing characteristics and patterns within metropolitan area by using spatial analysis methods mathematical statistics. The results show that: (1) Migrating are mainly mixed-ownership foreign-funded or privately-owned enterprises. Medium-sized more likely to relocate than small large enterprises, especially lucrative sectors. (2) based...

Using the precipitation data given by high-density regional automated weather stations during main flood season in Hunan Province, 2013, Cressman algorithm is introduced to calculate value 0.01°×0.01° resolution and compared with methods of a reciprocal distance square, exponent, square exponent. It shown that construction finer closer features gage than other methods. Precipitation accumulation amount agreement those obtained using range exponent as well. Cross-validation tests show number...

EXTRACTION OF CLIMATE INFORMATION FROM CHINESE HISTORICAL WRITINGS* Zhang Peiyuan This paper documents methods of extracting data on climate—specifically temperature and precipitation—from Chinese historical records. Relevant sources include local gazetteers, official histories, memorials to the emperor, personal private writings. Together they make it possible collate information precipitation over much empire for a period up five hundred years. China's voluminous writings have frequently...

Traditional image classification techniques are complex for data acquisition, feature extraction and model prediction with low recognition accuracy, so a more efficient simple methods easy operation high accuracy needs to be urgently proposed improve the traditional accommodate large amount of processed at this stage. Recently, optimization convolutional neural network technology has been upgraded provide solid foundation scene models, deep learning framework based on TensorFlow is build...

The article is devoted to a rather poorly studied topic. It outlines the dynamics of Chinese-Russian border trade and economic relations at end 20th – beginning 21st century, which are developing based on agreements comprehensive strategic partnership. information published in Russian Chinese literature, including works graduate students who prepared thesis research written similar topic Russia. reveals positive development, as well many problems that exist this segment cooperation....

The Internet economy is a new economic phenomenon from the era of information networking. can use technical means to achieve breadth and depth human communication could not reach in past. has had an impact on many traditional real economies caused disruptive effect selling methods marketing models. To explore economy, this study selects typical industries - restaurant industry food delivery. This achieves following main objectives. Examines delivery industry. What are positive negative...
