本文利用2019年中国家庭金融调查（China Household Finance Survey，缩写 CHFS）的相关数据，实证研究了独生子女性别对家庭金融资产投资选择和深度的影响。结果表明：子女性别影响家庭金融资产选择，独女家庭会显著提升风险金融资产投资的可能性和占比，独子家庭相反；存在地域男性偏好所导致的内生性，这导致极大低估了独生子女家庭中子女性别对风险资产投资的作用，一定程度上高估了家庭收入、户主受教育水平和家庭风险态度对风险资产分配的促进作用；异质性角度来看，农村家庭、东部和中部家庭在金融投资时更重视子女性别，东北部家庭参与股市时收入和风险态度是首要考虑；具备更高家庭收入、高风险偏好、多房产和高教育水平的家庭户主会重视风险金融资产投资，此结论在内生性和稳健性检验中均成立。

Based on the data of 2019 China Household Finance Survey (CHFS), this paper empirically studies the influence of the gender of only child on the investment choice and depth of family financial assets. The results show that: the gender of children significantly affects the choice of financial assets in families, the only daughter family will significantly increase the possibility and proportion of risky financial assets investment, the only boy family on the contrary; There is endogeneity caused by regional male preference, which greatly underestimates the effect of the gender of children on risk asset investment in one-child families, and overestimates to some extent the promoting effect of family income, the education level of the household head and family risk attitude on risk asset allocation.; From the perspective of heterogeneity, rural families, eastern and central families pay more attention to the gender of children in financial investment while income and risk attitude are the primary considerations when participating in the stock market in the northeast; The heads of households with higher household income, higher risk preference, multiple houses and higher education level will pay more attention to investment in risky financial assets.
