中国证券市场股票指数决定机制的计量分析

中国证券市场受到多种因素的影响,股票指数作为证券市场总体状况的衡量标准有着举足轻重的作用,因此研究股票指数的决定机制是至关重要的。针对中国证券市场总体状况所受的影响因素,着重对股票指数决定机制进行研究,使用最小二乘法、逐步回归分析等方法,使用Excel、EViews等软件编程计算,得到股票指数与GDP增长率、CHIBOR等因素的模型[1]。并且逐步解决可能存在的多重共线性、异方差性、自相关性。最后对中国证券市场的不足提出了政策建议。     

担保网络对企业创新的影响研究

本文选取2008~2020年A股上市公司的面板数据,采用普通最小二乘回归、Heckman两阶段回归、倾向得分匹配等方法系统检验担保网络对企业创新投入和产出的影响。研究发现:担保网络显著抑制企业创新投入与创新产出,且这一影响的具体路径是担保网络的“风险效应”;进一步检验发现,企业加入担保网络的平均最短路径越短、节点数越多,企业创新水平越低。研究结论揭示了担保网络对企业创新的影响机理,为促进担保网络内企业的创新活动提供了参考依据。     

基于空间非均衡视角的"大城市病"成因研究

本文通过多次实验,选取空间自相关程度最为显著的距离阈值,设定空间权重矩阵,使得空间权重矩阵更加符合我国城市分布特征,充分体现人口在城市集聚过程中的空间自回归机制,并结合广义空间模型和广义空间两阶段最小二乘法,实证探查“大城市病”成因,研究发现:就业机会、流通经济布局和公共服务的空间非均衡是导致人口过度集聚,从而引致“大城市病”的显著相关因素,并针对以上因素给出了对策建议。     

Investor sentiment and stock volatility: New evidence

This study investigates the predictability of sentiment measure on stock realized volatility. We propose a new investor sentiment index (NISI) based on the partial least squares method. This sentiment index outperforms many existing sentiment indicators in three aspects. First, in-sample result shows that the NISI has greater predictive power relative to the others. Most sentiment indicators show predictability in the non-crisis period only while the NISI is also effective in the crisis period. Furthermore, the NISI exhibits more prominent superiority in longer horizons forecasting. Second, further analysis indicates that the NISI has robust predictability before and after the Chinese stock market turbulence periods while the others not. Importantly, the NISI is still effective significantly after considering leverage effect while most of the others not. Finally, out-of-sample analysis demonstrates that the NISI is more powerful than other sentiment measures. This result is reproducible in different robustness checks.     

The links between active cooperation and eco-innovation orientation of firms: A multi-analysis study

The environmental orientation of companies is key for firms to gain a competitive advantage against peers. However, the high level of novelty and uncertainty involved with eco-innovations requires additional knowledge and capabilities that go beyond the firm and that can be achieved through cooperation. Thus, it is crucial to analyse how cooperation affects the elements that drive eco-innovation. This study tests the impact of cooperation on the environmental orientation of companies while innovating using structural equation modelling with partial least squares and multigroup analysis and a fuzzy-set qualitative comparative analysis for a sample of Spanish companies. Results suggest that companies that do not cooperate are less eco-innovation-oriented and show lower dependence on external information sources, although their impact on the orientation to product and process innovation is higher. This work leads to some theoretical conclusions and implications for researchers and practitioners.     

Chronological changes of government sectors’ fiscal policies and fiscal sustainability in Japan

Since the end of the 1990 s, the sluggish growth of Japan’s gross domestic product (GDP) and the mired fiscal state of its public sector have provoked consternation about its public sector’s fiscal sustainability. Therefore, I estimated the fiscal reaction functions (stemming from Bohn, 1998a, 2008) with time-varying parameters for all Japan’s government sectors (for 1976Q2–2020Q1), i.e., the general government (GG), the central government (CG), the whole of the local governments (WLG), and the whole of the social security funds (WSSF), to chronologically assess their fiscal sustainability using four different models, including a least-squares with breakpoints model and a state-space model with the Kalman filter. My results demonstrate that (1) the least-squares with breakpoints model outperformed the others, and (2) although CG, WLG, and WSSF often sustainably managed their finances during the analysis term, GG has failed to implement a sustainable fiscal policy from the mid-1990 s (3) CG and WSSF adjusted their fiscal postures according to Japan’s economic state. Fiscal severity caused WLG to change its fiscal posture.     

Birth order and intergenerational income mobility in Japan: Is the first-born child different?

This study examines how birth order affects intergenerational income mobility (IGM) in Japan, focusing on the difference in IGM between firstborn and later-born children. The elasticities of sons’ income with respect to fathers’ income are separately estimated for sons who are firstborn and sons who are later born by family size using a two-sample, two-stage least squares approach. For sons born in 1926–1981, this study finds that in families with four or more children, intergenerational income elasticity (IGE) for firstborn sons is substantially and significantly higher than that for later-born sons. However, no significant birth order effects are found in households with two or three children.     

Housing Boom,Dutch Disease,and the Decline in China's Manufacturing Exports

Drawing on Dutch disease theory, we assess how the recent housing boom has contributed to a decline in China's manufacturing exports. Using Chinese city and enterprise panel data from 2004 to 2013, our analysis reveals that Dutch disease indeed exists and that the housing price increase has played a very important role in affecting China's manufacturing exports through two key channels: resource movement effect and spending effect. Specifically, this paper found that: (i) the housing price increase hindered labor flowing into China's manufacturing industry (resource movement effect) and caused higher inflation (spending effect); (ii) the housing boom clearly impeded China's manufacturing exports, especially after the outbreak of the global economic crisis in 2008; (iii) the impacts of the housing price increase on China's manufacturing exports were heterogenous, and were more significant for labor-intensive manufacturing businesses, businesses that were foreign owned, less R&D intensive, or located in the central and western regions.
