Features and Comparative Research on Ecological Civilization Vocabularies in the Five-Year Plan of China: An Analysis Based on Semantic Phrases

Abstract

The Five-Year Plan (FYP) in China guides the social and economic development. The features of ecology-related vocabularies in national and regional FYPs help to study China’s emphasis and focus on ecological civilization. In this paper, a multi-phrase dictionary with syntactic and semantic features is constructed to analyze the features and trends of ecology-related vocabularies through social network and phrase topic model. Then, based on studies on the 13th and 14th FYPs of China and 31 provinces and cities, it is found that remarkable different stage definitions and tasks of ecological civilization construction are proposed according to different description vocabularies, with more pragmatic measures to fulfill its “carbon” target in 2030 as a duty-bound responsibility and mission to cope with climate change. The research ideas and methods in this paper can provide references for similar policy text analysis, and the conclusions from empirical studies are helpful to grasp the focus and trends of ecological civilization-related policies in China and various provinces and cities.
