Mining research and invention activity for innovation trends: case of blockchain technology

Regulation as a pathway to individual adoption of cryptocurrency

Purpose

The purpose of this paper is to investigate the antecedents of individuals’ behavioral intention to transact in blockchain cryptocurrency through the theoretical lens of the expanded theory of planned behavior (TPB).

Design/methodology/approach

This study investigated the antecedents of a blockchain cryptocurrency adoption framework by adapting well-established items from the information systems (IS) and psychology literature to produce a survey instrument to measure individuals’ intention to engage in blockchain cryptocurrency transactions. The survey was administered to 492 individuals through Amazon Mechanical Turk.

Findings

This study resulted in a research model of an individual’s intention to transact with a blockchain cryptocurrency. Results indicated that the expanded TPB model explains 63.5% of the variance in intention to adopt cryptocurrency for transactional usage. In this study, all paths leading to behavioral intention were found to be significant in the hypothesized directions. In addition, all paths leading to attitude, subjective norms and perceived behavioral control were found to be significant in the hypothesized directions.

Originality/value

This study furthers prior literature by empirically validating the expanded TPB in the context of individuals’ intention to use cryptocurrency for transactional purposes. This study can better inform practitioners on individual attitudes and behaviors toward transactional cryptocurrency use. The findings provide regulators meaningful insights toward the development of a regulatory framework which encourages innovation while safeguarding the interests of individual citizens.

Applying data mining techniques for technology prediction in new energy vehicle: a case study in China

Technology prediction is an important technique to help new energy vehicle (NEV) firms keep market advantage and sustainable development. Under fierce competition in the new energy industry, there is an urgent necessity for innovative technology prediction method to effectively identify core and frontier technologies for NEV firms. Among the various methods of technology prediction, one of the most frequently used methods is to make technology prediction from patent data. This paper synthesizes the frequent pattern growth (FP-growth) algorithm and input-output analysis to construct a new technology prediction method based on the knowledge flow perspective, takes the data of NEV patent family in 1989-2018 the Derwent patent database as a sample, divides the data according to the 5-year standard, and uses the method to identify the core and frontier technologies in the NEV field during different periods. Furthermore, the multiple co-occurrence method applies to analyze the technology layout and evolution patterns in China's NEV field. The results show that the technology prediction method proposed in this paper can effectively identify core and frontier technologies to achieve NEV technology prediction.

The Sustainable Development of Financial Topic Detection and Trend Prediction by Data Mining

Blockchain technology is the most cutting-edge technology in the field of financial technology, which has attracted extensive attention from governments, financial institutions and investors of various countries. Blockchain and finance, as an interdisciplinary, cross-technology and cross-field topic, has certain limitations in both theory and application. Based on the bibliometrics data of Web of Science, this paper conducts data mining on 759 papers related to blockchain technology in the financial field by means of co-word analysis, bi-clustering algorithm and strategic coordinate analysis, so as to explore hot topics in this field and predict the future development trend. The experimental results found ten research topics in the field of blockchain combined with finance, including blockchain crowdfunding, Fintech, encryption currency, consensus mechanism, the Internet of Things, digital financial, medical insurance, supply chain finance, intelligent contract and financial innovation. Among them, blockchain crowdfunding, Fintech, encryption currency and supply chain finance are the key research directions in this research field. Finally, this paper also analyzes the opportunities and risks of blockchain development in the financial field and puts forward targeted suggestions for the government and financial institutions.
