In this article, we consider sample data from 30 regions in China 2004 to 2020. We use the entropy method measure high-quality development level, then examine intermediary and threshold effects verify main paths by which green technology innovation mediates relationship between environmental regulation intensity quality of economic development. Our conclusions are as follows: (1) There is a “U”-shaped When low, there negative (inhibitory) two, while positive (promoting) when high....

Abstract This paper presents a new algorithm to calibrate the option pricing model, i.e. that recovers implied local volatility function from market prices in optimal control framework. A unique is shown exist. Our well-posed. numerical experiments show that, with help of techniques developed field control, recovered very well.

Financial vulnerability is an important issue in livelihood resilience research domain. In the context of Farmland Property Rights Reform rural China and promotion farmland circulation, this study aims to explore whether how household financial affected by circulation its impact shows heterogeneous characteristics depending on differences farm regional characteristics. To answer these questions, a theoretical empirical was conducted based latest available Chinese survey data ( N = 9,822)...

Green and low-carbon development has become a compelling trend of our time. To formulate policies for also reduction carbon emissions, quantifying the tourism in green sustainable is an essential issue China, which undergoing economic transformation. This study first measured China’s domestic emissions through bottom-up approach then used robust Granger causality test on annual data from 1993 to 2019 investigate relationships among revenue, growth. The empirical results show that: (1) Carbon...

During the COVID-19 pandemic, medical products have been crucial to global fight against disease. As a major manufacturing country, China occupies an important position in field. However, China's terms of trade are not commensurate with its status as exporter products. Therefore, studying market power product exports has practical significance for determining value chain and then proposing policies measures enhance power. The findings this paper, utilizing HS 6-digit data from 1992 2020,...

This paper contributes to the tourism–growth literature by applying new vector autoregressive-based Granger causality test in presence of instability reassess between Hong Kong’s tourism and economic growth. The results traditional recursive under VAR framework show that tourism-led growth hypothesis (TLEGH) economy-driven (EDTGH) are both unstable Kong. generally support bidirectional However, relationship is vulnerable sudden major political incidents, public health financial crises. Among...

Testlet design has been widely adopted in educational and psychological assessment. A testlet is a cluster of items that share common stimulus(e.g., reading comprehension passage or figure), the possible local dependence among within called testlet-effect. Various models have developed to take into account such effect. Examples included Rasch model, two-parameter logistic Bayesian higher-order model. However, these existing all assume an item affected by only one single Therefore, they are...

Visual perception plays a leading role in tourism destination marketing. In the era of Web 2.0, it is critical to understand whether and how circle representation has changed visual representation. The research combines photo data from internet interview explore mechanism TDI. Through both content thematic analysis, finds that: (1) diverse sources result differences similarities between projected perceived images destination; (2) still valid. icons were photographed repeatedly due impacts...

The fractal characteristic of the electricity market has attracted significant research attention in recent years. And heterogeneous microstructure analysis behaviors represent a natural step forward to understanding and modeling complex price behaviors. In this paper, we introduce Empirical Mode Decomposition (EMD) analyze underlying market. Multifractal Detrended Fluctuation Analysis method (MFDFA) is used characteristics EMD decomposed domain. studies have been conducted four markets...

The report of the 20th National Congress Communist Party China strongly emphasized necessity to increase financial system stability and secure equipment manufacturing sector. This paper devotes provide a highly efficient dynamic strategy against risk contagion across these two sectors. Based on volatility spillover network, processes with without immunization were simulated separately Python investigate gain. Discovering that, strategy, number contagious nodes reduced by 60% while immunizing...
