摘 要
人寿保险行业作为具有极大发展潜力的产业之一,目前正处于加速发展的阶段。由于我国不同省市间存在经济及文化差异,了解不同地区寿险发展的影响因素有助于各省市针对自身情况制定独特有效的发展策略。因此本文基于2009-2018年我国31个省级行政单位(不含港澳台地区)的面板数据对不同区域的寿险需求进行研究。
本文基于各地区的综合发展指数进行了区域划分,以地区寿险密度作为度量指标,选取了经济、社会及价格三方面共计十一个因素进行地区寿险需求分析。在对各组数据进行单位根检验及面板检验的基础上创建了线性回归模型,先采用了最小二乘法进行线性回归,对于结果不显著的组别进行了变量间的多重共线性检验,最后对具有共线性的组别采用岭回归的方法进行修正,得到了处于不同发展阶段的地区寿险发展的影响因素。结果显示,对于综合发展水平不同的地区,寿险发展受到不同因素的差异性影响,其中北京市作为综合发展最佳的城市受到九个因素的影响、上海市及天津市作为综合发展较好的地区受到七个因素的影响、以江苏省为代表的综合发展处于中等水平的四个省市受到七个因素的影响、以辽宁省为代表的综合发展位于中下水平的十七个省市受到六个因素的影响、以云南省为代表的综合发展较为落后的七个省市受到九个因素的影响。文中分别建立了五组地区的寿险影响因素的回归方程,并根据不同指标对各组地区及我国整体寿险市场的影响状态异同进行了具体分析。
本文根据五组不同发展条件的地区的寿险发展需求提出了具有针对性及普适性两个方向的建议。对于各地区而言,应该针对不同因素对寿险发展的独特影响采取相应措施,如:对于北京市可以通过推进二胎等政策刺激消费者的寿险需求。对于国家而言,应合作推行市场利率化、提升市场化程度,对于寿险企业而言应善于运用统计及信息技术开发潜在市场。

Abstract
Based on great development potential, life insurance industry in China is developing apace. Because of the economic and cultural differences between provinces in China, understanding the factors that influence the development of life insurance in different regions is helpful to develop unique and effective strategies. Therefore, based on the panel data from 2009 to 2018 of 31 provinces in China, this paper studied the demand for life insurance in different regions.
Based on the comprehensive indexes of each region, the provinces were divided into five groups. The paper took the density of regional life insurance as the measurement index, and selected 11 factors from three aspects to study the regional life insurance demand. Based on the unit root test and panel test, a linear regression model was created. First, the ordinary least squares estimation method was used for linear regression, and multicollinearity tests were carried out among variables for groups with insignificant results. Then, ridge regression method was used for correction of groups with collinearity. Finally, the factors affecting life insurance in regions were obtained. The results show that for regions with different comprehensive development levels, the process of life insurance is affected by different factors. Beijing, as the best developed city, is influenced by nine factors. Shanghai and Tianjin as the optimal comprehensive development area is affected by seven factors. The four provinces in the middle level of comprehensive development, represented by Jiangsu province, are affected by seven factors. The 17 provinces in the lower levels of comprehensive development, represented by Liaoning province, are affected by six factors. The seven provinces with relatively backward comprehensive development, represented by Yunnan province, are affected by nine factors. In this paper, the regression equations of the related elements of life insurance in five groups of regions are created respectively, and the differences and similarities of the influencing states of each group and China's overall life insurance market were analyzed.
Based on the demand of life insurance in five groups, this paper puts forward suggestions with pertinence and universality. For each region, solutions should be collected according to the unique influence of different factors on the development of life insurance. For example, Beijing could stimulate consumers' demand for life insurance by promoting policies such as Two-child. For China, the country should promote market interest rate and marketization. For life insurance companies, they should make statistics and use technology to develop potential markets.

1.1.1 选题背景
寿险作为人身保险的一种,是以被保险人的寿命为保险标的,以被保险人生存或死亡为给付条件的人身保险[1]。我国于1980 年恢复国内商业保险业务, 1982 年正式恢复人寿保险业务。寿险行业恢复以来历经波动性发展:由上世纪90年代的寿险业复苏发展,到2000年初银行业与寿险业合作模式的快速扩张,至2010年底新规整顿市场,保费收入不断下降,直到2014年随着资本市场转暖,保险公司投资回报有所保证,而2017年至今,行业管理更加有力,着重推行保障型产品。
截至2019年底,尽管保费收入千亿以上的公司的行业龙头地位未曾得到撼动,但百亿规模的保险公司在保费收入及市场份额方面都有一定提升。当今寿险行业,消费者已不再局限于根据公司品牌进行投资,而趋向于选择更加适合自己及后续服务更加完善的产品。
