中国耕作制度的历史演变及当前轮作休耕制度的思考

本文采用文献法和比较法，对中国耕作制度的历史演变进行梳理和总结，探讨当前中国实行耕地轮作休耕制度的现实背景，归纳轮作休耕国家试点和地方试验的做法，分析传统耕作制度对轮作休耕的经验意义，提出完善轮作休耕制度的思路。研究发现：（1）中国主要经历了撂荒耕作、休闲耕作、连作耕作和复种轮作4种耕作制度，形成了精耕细作的土地用养结合模式及相关的一整套技术措施。（2）目前高度集约化的复种轮作制使耕地产能严重透支，耕地总体健康状况堪忧。（3）中国实行轮作休耕可从传统的用地养地模式中汲取经验，但并非简单的复制。（4）实行轮作休耕制度需要综合考虑国内外制度基础和政策环境，需要在区域操作模式、技术路径、时空配置等方面进行完善。     

The effect of inspections,rotations and client preferences on staffing decisions

With increased regulatory focus on audits and concerns about whether audit regulation is achieving its stated aims, it is timely to investigate how regulator inspection of audit files and partner rotations may be affecting staffing decisions. This is an important issue, which affects all audits, as the calibre of staff allocated across engagements impacts the quality of audit work delivered. This study reports the results of an experiment where auditor participants allocate staff across two audits, where regulation anticipated (none, inspection, rotation) and a client request for the best staff (absent, present) are manipulated between‐subjects. We find that auditors allocate lower calibre staff when neither an inspection nor rotation is anticipated than when either is anticipated. When an inspection is anticipated, auditors allocate staff with more knowledge and compliance skills. When a rotation is anticipated, auditors allocate staff with more people skills. A client request for the best staff only has an effect when a partner is due to be rotated, where auditors allocate staff with more people skills in response to the client request. Our findings provide greater understanding of staffing decisions, which may affect audit quality if concerns around audit inspections and partner rotations are perceived by auditors as more important than the underlying risk or complexity of an engagement when allocating staff.     

非住宅建设用地使用权续期规则的思考

研究目的:分析非住宅建设用地使用权续期活动的规则与性质,提出完善续期规则的建议。研究方法:规范分析法,比较分析法。研究结果:非住宅建设用地使用权的续期规则存在疏漏,使续期申请的起止期间难以清晰界定,以私法视角理解续期活动也不妥当。研究结论:续期是申请人取得重新设立的建设用地使用权的过程,因此要求在续期过程中必须清晰界定续期权利的设立与灭失期间,保证续期或救济得以顺利进行。续期也是获得行政特别许可的结果,应当采用协议出让方式予以确认。     

"十四五"规划时期中国需要开展农民工市民化攻坚战

农民工市民化攻坚战是要在基本实现社会主义现代化新阶段的15年内使得近两亿已经和将要在城镇稳定就业的农民工中的大多数基本上成为市民；其必要性在于，这是新阶段基本实现社会主义现代化的客观要求、基本实现高质量新型城镇化和优化城乡结构的主要任务、更好地解决“三农”问题的重要措施、促进城镇发展和稳定的有益途径，是农民工市民化更有效的战略措施，也有助于推动全面深化改革、有效扩大内需；其可能性在于，无论从资金筹集方面来看，还是从制度改革创新方面来看，都基本具备实现农民工市民化的条件；其主要战略措施包括，由党和国家统一规划部署、综合配套、协调推进，实行市民化和回乡创业就业双管齐下的战略方针，以相关制度改革创新和有效筹集使用相关资金为战略重点等。     

LABOUR PRODUCTIVITY GROWTH IN THE LONG RUN: JAPAN, 1600–1909

This article examines long-term labour productivity change in Japan from the early seventeenth century to the nineteenth century. We constructed sectoral labour force estimates based on the methodology presented in a previous study, who provided a sectoral GDP series covering the Tokugawa period. Our results show the industrial structure in the Tokugawa period remained relatively stable in comparison with the economy after the Meiji Restoration. Nevertheless, the estimates of sectoral labour productivity suggest expansion of the market economy in Tokugawa Japan influenced the development of industrialisation after the Meiji Restoration.     

Noise from online discussion forums: Evidence from IPOs in China

In this study, we use initial public offerings (IPOs) in China to investigate how online stock forums influence information asymmetry and IPO valuation. The empirical analysis isolates the underpricing and overvaluation components of initial returns. The number of forum comments, postings, and readings are positively associated with initial returns and the degree of underpricing, implying that forums create noise that exacerbates information asymmetry during IPOs. This effect is amplified by the quiet period regulation, which drives investors to rely on online discussion forums to obtain information. Through sentiment analyses of forum posts and media coverage, we find that the negative effect of online forums is more prominent when bad news prevails. We clarify the role of online stock forums in IPO pricing and information asymmetry by separating underpricing from overvaluation in initial returns.     

Official rotation and corporate innovation: Evidence from the governor rotation

Rotation is a practice whereby officials are regularly moved between equally ranked positions. Focusing on governor rotation, this paper examines the effect of official rotation on corporate innovation in China. First, we find that official rotation significantly promotes corporate innovation, including enterprises’ innovation investment, quantity, and quality. Second, we find that the effect of official rotation on corporate innovation varies because of official and regional heterogeneity. Officials rotating from other provinces significantly stimulate corporate innovation, but officials rotating from the central government have an insignificant influence on corporate innovation. In addition, officials rotating to non-eastern regions significantly enhance corporate innovation, while officials rotating to eastern regions have a negligible impact on corporate innovation. We further examine the driving mechanism behind the effect of official rotation on corporate innovation and find that officials rotating from eastern regions to non-eastern regions can significantly promote corporate innovation, but officials rotating from non-eastern regions to eastern regions do not boost corporate innovation. These findings imply that the different effects of official rotation on corporate innovation are due to the official experience effect. We also find that official rotation can promote corporate innovation through reducing corporate charitable donations and increasing corporate innovation subsidies. In a supplementary analysis, we find that GDP-oriented performance appraisal pressure weakens the effect of official rotation on corporate innovation. The lower the pressure on officials regarding their performance, the more significant the effect of official rotation on corporate innovation. In addition, official rotation can significantly promote the development of the regional economy and improve the GDP growth rate via corporate innovation, which is a micro-level economic growth effect of official rotation. Overall, our findings further verify the economic effect of official rotation and extend our understanding of the influencing factors of corporate innovation from the perspective of the official governance system. Our findings also have clear policy implications for how the government can improve the official governance model to promote corporate innovation during the transition period of the national innovation system.     

我国煤炭波动周期分析与近中期发展趋势推演

通过对我国改革开放以来GDP增速、煤炭消费增速历史数据的分析,发现不管是经济发展,还是煤炭发展过程中都存在周期性的波动变化规律。而通过对煤炭与经济波动曲线的拟合,发现煤炭与经济发展呈协同波动变化。基于以上煤炭与经济协同波动规律,对未来煤炭与经济发展走势进行了推演,发现煤炭消费增速最早要在2015年前后才能企稳提高,由此进入新一轮上升期。综合分析表明,煤炭抗波动能力较弱,未来要实现煤炭平稳发展,需根据经济发展节奏的不断变化,及时主动地调整煤炭发展步伐,从而避免因煤炭发展的冒进或硬着陆给煤炭及关联产业发展带来长时间、高强度的冲击和损害。     

基于剩余评价期的经济评价方法研究及在长输管道中的应用

针对传统的内部收益率存在参数条件变化需要对数据进行还原调整,且历史数据缺失时无法使用,或企业管理者不注重历史收益状况的情况,提出了基于管道项目剩余评价期的内部收益率指标,并结合油气长输管道运营实际,分别构建了运营期现金流量均衡、非均衡两种情形下的评价模型,计算分析了不同剩余评价期内部收益率与全评价期基准收益率的对应关系。最后针对某管道企业的3条管道进行了实例测算,对测算结果进行分析和评价。     

How local leaders matter: Inter-provincial leadership transfers and land transactions in China

We study how local leaders matter for economic growth by examining the impacts of exogenous transfers of leaders across China’s provinces on land transactions in the primary market. We find that new provincial leaders attract investment in industrial land from the provinces of their previous positions. The leaders’ impacts are greater when their freedom to deploy their business connections in the land market is greater. More importantly, we find evidence of positive impacts of land transactions on economic growth, which should bode well for the careers of the local leaders, albeit there is some evidence of rent seeking among officials especially when they are too old for further promotion.
