Europe is an important part of the construction of the “Belt and Road”，which is characterized by capital intensive and technology intensive. Developed industries and science and technology in Western Europe occupy a leading position in many fields of the world，while the tertiary industry also leads the world in many fields，so the European economy is highly complementary. However，in recent years，the European debt crisis，refugee crisis，deindustrialization，populism wave，the rise of polarized parties，anti-china suspicion and China and other phenomena have jointly demonstrated the division and crisis in Europe，so we can analyze the impact of the continuous investment environment in the political，social and economic fields. Based on the analysis framework of political sociology and political social phenomena，this paper evaluates the investment environment risk of the “Belt and Road” construction in Europe.
