This paper explores the impact of risk preference as well as interlinked credit and insurance contract on peasants' new technology adoption. The results show that (1) risk preference has a significant impact on peasants' adoption of innovative seeds, and the influence of exact probabilistic risk...

The probability of two nodes to be linked is related to their similarities in the network. Based on statistical inference, a network-structure similarity index, therefore, is proposed to find the potential links. This index quantifies the effects of the node communities on these links. And an...

Large-scale data are analysed using the Wigner function. It is shown that the ‘frequency variable’ provides important information, which is lost with other techniques. The method is applied to ‘sentiment analysis’ in data from social networks and also to financial data.

A method, based on symmetry considerations, is presented by which the size of the shift operator matrix appropriate to an M x ∞ lattice with periodic boundary conditions (in the M-direction) can be reduced by a factor of M-1. Since the computation time required to obtain the eigenvalues of...

We argue that the statistical character of wave propagation in random media can be described in terms of two universal parameters which are average properties of eigenmodes of the field. We show that the width and spacing of electromagnetic modes can be determined from the measurement of the...

This study takes the central, provincial and municipal Environmental Protection Interviews (multi-hierarchical EPI) as a mechanism innovation for precise environmental regulation in Yangtze River Delta (YRD) and constructs a multi-cutoff regression discontinuity design to accurately measure the...

The COVID-19 brings about a great quantity of digital entrepreneurs in China. In the fierce competition, positive psychological capital can better help them adjust emotions, cognition and behavior. However, little is known of how to improve the digital entrepreneurial psychological capital...

Due to the inherent complex tensions in General Purpose Technology (GPT) in emerging industries, namely those between "generality" and "emergance," firms in emerging industries often face the dilemma of choosing distant search or local search in GPT innovation. The core research question of this...
