초록

본 연구는 시간의 흐름에 따른 부동산 정책의 주제 동향과 부동산 정책에 대한 대중의 감성 여론을 파악하고자 하였다. 부동산 정책 관련 키워드('부동산정책', '부동산대책')를 이용하여 2008년 2월 25일부터 2021년 8월 31일까지 13년 6개월 동안 작성된 총 91,740개의 트위터 게시물을 수집하였다. 데이터를 전처리하고 공급, 부동산세, 금리, 인구 분산으로 범주화 하여 총 18,925개의 게시물에 대하여 감성 분석과 다이나믹 토픽 모델 분석을 진행하였다. 범주별 키워드는 공급 범주(임대주택, 그린벨트, 신혼부부, 무주택자, 공급, 재건축, 분양), 부동산세 범주(종부세, 취득세, 보유세, 다주택자, 투기), 금리 범주(금리), 인구 분산 범주(세종, 신도시)와 같다. 감성 분석 결과, 한 명이 평균 하나 또는 두 개의 긍정 의견을 게시한 걸로 확인되었고, 부정, 중립 의견의 경우, 한 명이 두 개 또는 세 개의 게시물을 게시한 걸로 확인되었다. 또한 일부 대중들은 부동산 정책에 일관된 감정을 가지고 있지 않고 긍정, 부정, 중립의 의견을 모두 표현하는 것을 유추할 수 있었다. 다이나믹 토픽 모델링 결과, 부동산 투기 세력, 불로소득 주제에 대한 부정적인 반응이 꾸준히 파악되었으며, 긍정적인 주제로는 주택 공급 확대와 무주택자들의 부동산 구입 혜택에 대한 기대감을 확인할 수 있었다. 본 연구는 기존 선행연구들이 특정 부동산 정책의 변화와 평가에 초점을 맞춰 분석한 것과는 달리, 소셜미디어 플랫폼 중 하나인 트위터에서 게시물을 수집하고 감성 분석, 다이나믹 토픽 모델링 분석을 활용하여 부동산 정책 평가자인 대중의 감성과 여론을 알아보고 시간의 흐름에 따른 부동산 정책에 관한 잠재적 주제와 동향을 파악했다는 것에 학술적 의의가 있다. 또한, 본 연구를 통해 부동산 정책에 대한 대중의 여론에 기반한 새로운 정책 제정에 도움을 주려고 한다.

This study aims to understand the trends of subjects related to real estate policies and public's emotional opinion on the policies. Two keywords related to real estate policies such as "real estate policy" and "real estate measure" were used to collect tweets created from February 25, 2008 to August 31, 2021. A total of 91,740 tweets were collected and we applied sentiment analysis and dynamic topic modeling to the final preprocessed and categorized data of 18,925 tweets. Sentiment analysis and dynamic topic model analysis were conducted for a total of 18,925 posts after preprocessing data and categorizing them into supply, real estate tax, interest rate, and population variance. Keywords of each category are as follows: the supply categories (rental housing, greenbelt, newlyweds, homeless, supply, reconstruction, sale), real estate tax categories (comprehensive real estate tax, acquisition tax, holding tax, multiple homeowners, speculation), interest rate categories (interest rate), and population variance categories (Sejong, new city). The results of the sentiment analysis showed that one person posted on average one or two positive tweets whereas in the case of negative and neutral tweets, one person posted two or three. In addition, we found that part of people have both positive as well as negative and neutral opinions towards real estate policies. As the results of dynamic topic modeling analysis, negative reactions to real estate speculative forces and unearned income were identified as major negative topics and as for positive topics, expectation on increasing supply of housing and benefits for homeless people who purchase houses were identified. Unlike previous studies, which focused on changes and evaluations of specific real estate policies, this study has academic significance in that it collected posts from Twitter, one of the social media platforms, used emotional analysis, dynamic topic modeling analysis, and identified potential topics and trends of real estate policy over time. The results of the study can help create new policies that take public opinion on real estate policies into consideration.
