(A) conceptualization and index development of mobile connectedness in digitalizing cities

국문 초록 (Abstract)

본 연구는 모바일 연결성을 개념화하고 개개인과 모바일 인터넷 간의 관계 품질을 측정하는 지표를 개발하는 것을 목표로 한다. 이를 위해 중국 도시 거주자를 대상으로 온라인 설문 조사를 실시하였다 (N = 569). 본 연구에서는 스마트폰 목표 범위, 스마트폰 목표 강도, 스마트폰 활동 강도, 스마트폰 활동 범위 등 4개 항목으로 모바일 연결성을 구성하였고 통계검증을 통해 모바일 연결성 지표의 신뢰도와 타탕도를 확인하였다. 이 연구는 모바일 연결성이 스마트폰 자아 효능감에 미치는 영향도 검증했는데, 모바일 연결성 지표가 높은 집단이 더 높은 스마트폰 자아 효능감을 지니고 있는 것으로 나타났다. 스마트폰 활동에 대한 주성분 분석은 스마트폰의 이동성과 공간적 사용이 스마트폰 활동의 핵심적인 차원을 형성함을 보여주며, 모바일 연결성은 개인-모바일 인터넷 관계를 설명하는 개념으로 기존의 인터넷 연결성과 다른 특성을 지니고 있음을 확인하였다.

This research aims to conceptualize mobile connectedness and develop an index that measures the quality of the relationship between individuals and the mobile Internet. This study conducted an online questionnaire survey with urban residents between 18 and 76 in mainland China (N = 569). Confirmatory factor analysis showed that the mobile connectedness index—consisting of four items in a single factor, including smartphone goal scope, smartphone goal intensity, smartphone activity intensity, and smartphone activity scope—was valid and reliable. The study also explored the effects of mobile connectedness on smartphone self-efficacy, which showed a significant positive relationship. Principal component analysis of smartphone activity indicates that the smartphone's mobility and spatial use form the vital dimension of smartphone activity, revealing a different characteristic from the previously fixed Internet connectedness, which explains the individual-mobile Internet relationship.
