不同技术密度部门工业智能化的就业效应——来自中国制造业的证据

本文通过引入智能化资本重构任务模型,刻画不同技术密度部门中工业智能化升级对就业人数变动的影响机理,利用省级面板数据检验智能化升级对高、低技术密度部门就业的净影响效应,同时结合企业面板数据验证了智能化就业效应的传导渠道.研究表明:在中国当前发展阶段的高、低技术密度部门工业智能化升级都能够显著促进就业增加,且高技术密度部门的就业增加效应要明显高于低技术密度部门;在低技术密度部门工业智能化升级能够激发其利用技术扩散,而在高技术密度部门则倾向于通过生产规模扩张渠道,促进部门内部不同规模的就业增加;智能化升级的正向就业效应在非国有控股企业和东部地区企业中最为突出.     

Tourism agglomeration and urbanization: empirical evidence from China

Tourism-driven urbanization presents a new way of exploring the construction of a new-type of urbanization. Consequently, the relationship between urbanization and the frequent agglomeration of tourism activities has attracted much research attention in recent years. This paper empirically investigates the influence of tourism agglomeration on urbanization using China’s provincial panel data for years 1999–2012. A panel data model with a fixed effect model and a two-step system generalized method of moments estimation is constructed to explore that influence. Results show that tourism agglomeration positively influences urbanization, and there exists a U-shaped relationship between these two variables. After capturing the dynamic nature of urbanization, we estimate the long-term tourism agglomeration elasticity in China as 0.4566. This paper provides theoretical and practical implications on urbanization of China in view of tourism agglomeration.

When Auditors Say ‘No,’ Does the Market Listen?

Previous research on whether the market responds to auditors’ opinions has provided mixed results. We revisit this issue in China, where individual investors who are more likely to neglect value-relevant information dominate the stock market. In addition to going concern opinions (GCOs), China permits modified audit opinions (MAOs) on violations of accounting standards or disclosure rules (GAAP/DISC MAOs), providing an opportunity not available in the literature to enrich the study of audit-opinion pricing. We find that, ceteris paribus, MAO recipients underperform in the future and have a higher incidence of adverse outcomes such as misreporting and stock delisting, and the market reacts negatively to MAOs during the short window around MAO disclosure. Importantly, MAO disclosure is not followed by negative long-term stock returns, suggesting stock price adjustments to MAOs are speedy and unbiased. These findings hold for both GCOs and GAAP/DISC MAOs. Together, our findings support the informativeness of audit opinions and cast doubt on the argument that investors inefficiently price audit opinions due to information-processing bias.     

Debt Covenant Restriction,Financial Misreporting,and Auditor Monitoring*

Theory suggests that financial report-based debt covenants engender incentives for the manager to relax covenant constraints through accounting choices in order to avoid costly covenant violations. Prior studies directly testing this hypothesis in the context of financial misreporting fail to find consistent evidence. Using a more refined measure of debt covenant restriction, we find that debt covenant restriction is positively associated with the probability of financial statement misstatements. This positive association is driven by performance covenants rather than capital covenants and is more consistent with the manager striving to avoid a “false-positive” violation than to delay the violation. Our results also imply that managers resort to both income-increasing and non–income-increasing misreporting to relieve covenant constraints and rely more on the latter when faced with greater earnings management constraints. Additionally, the auditor charges higher audit fees to firms with more binding covenants even outside the violation state, and audit fees increase with constraints relative to both performance and capital covenants, reflecting greater financial reporting risk and bankruptcy risk, respectively. Within capital covenants, we find some evidence of even higher audit fees for tighter intangible-inclusive versus intangible-exclusive capital covenants. Lastly, our evidence suggests that the positive association between covenant constraints and misreporting is attenuated when the auditor has more experience with debt covenants, has greater bargaining power over the client, or faces greater litigation risk.

Regional disparity of embedded carbon footprint and its sources in China: a consumption perspective

Carbon emission reduction could be achieved through extensive cooperation between relevant groups such as businesses, governments and consumers. Generally, carbon emissions stem from consumer behaviour. To tackle the increasingly serious energy crisis and climate change in China, it is thus vital to control carbon emissions generated by the country's urban consumers. From a consumption perspective, we utilize a self-organizing feature map model to analyse the spatial differentiation of per capita embedded carbon footprint (ECF) in urban China. We found that the spatial differentiation is significant with the per capita ECF of the east coastal area at a high level and that per capita disposable income is the key factor affecting ECF. Based on these findings, potential business opportunities to develop low-carbon products are discussed.
