论数据权益的刑法保护——民刑交错视角下的法益保护论探讨

关于“数据权益的刑法保护”问题，在理论层面上，可从“刑法解释论”和“刑法立法论”两种路径进行探讨。“刑法解释论”探讨路径以现行《刑法》罪名体系为出发点，主要任务是揭示哪些罪名的犯罪构成之设置是以“数据权益”为规范保护目的；“刑法立法论”探讨路径是在刑法立法层面上探讨立法者为在刑法政策上实现数据权益的刑法保护这一目的，动用刑罚禁止何种行为类型才具正当性的问题。然而，两种探讨路径都将依赖于“数据权益”的内涵确定以及法益格的认定问题，换言之，是刑法法益理论在数据权益刑法保护问题上的具体运用。《民法典》第127条并非是关于数据的确权性规定，且在民法理论界关于数据权益的法律属性存在诸多争议的状况下，“数据权益”内涵不明、法律属性不清导致其并不具备作为刑法保护客体的“法益”格。当前刑法理论界存在的关于“数据权益”的刑法类法益保护模式探讨路径，是对刑法法益保护方式的误读，并未触及“数据权益刑法保护”之规范层面问题的实质。“数据安全”法益观的探讨路径则不仅混淆了现象层面与规范层面上的“数据犯罪”概念的界分，也由于没有论证“数据安全”如何能够构成刑法的保护法益，而导致结论过于武断。在理论探讨上，应该明确作为行为客体的物理层面上的“数据”概念与作为保护客体的法益层面上的“数据权益”概念之间的区别，据此明确“数据权益的刑法保护”在规范层面上是否构成新问题。     

Persistence of Price–Cost Margin and Technical Efficiency in the Indonesian Food and Beverage Industry

Abstract

This research investigates the persistence of price–cost margin (PCM) and technical efficiency (TE) of firms and the relation between these two factors in 44 subsectors of the Indonesian food and beverage industry in the period 1980–2014. Data envelopment analysis with a bootstrapping approach is applied to estimate TE. An autoregressive model, accounting for endogeneity, is applied to estimate the persistence coefficients of PCM and TE. A cross-sectional regression model is also applied to estimate the relation between the persistence of the PCM and the persistence of TE. The results show that for these food and beverage firms, high PCM and low TE persist. Furthermore, the persistence of PCM negatively affects the persistence of TE in the industry.     

庚子赔款的债务化偿付及其影响

庚子赔款是中国近代史上最大一笔赔款,也是以长期债务形式体现的赔款。本文对庚子赔款的债务化偿付安排、利率水平、支付流程及经济影响等进行比较分析。发现:(1)庚子赔款本金4.5亿两,是清政府 1903 年财政收入的 4.33倍,但通过债务化偿付,每年支付赔款占财政收入比重逐步下降;(2)按购买力折算,庚子赔款本金约占1900年中国GDP的2.1%;(3)与当时主要国家长期债务利率相比,庚子赔款4%的利率属于中等水平;(4)将庚子赔款与德国“一战”赔款进行比较,发现赔款本金和占经济总量比重,中国低于德国,但中国每年支付赔款的财政压力高于德国;(5)庚子赔款偿付对近代中国的财税金融产生深刻影响,外籍海关税务司借机成为独立于中国政府的“第二财政”,外商银行藉此强化其“隐性中央银行” 地位,赔款还催生了货币流通的“新周期” 和“新危机”。总体上,赔款的债务化偿付安排不仅受政治外交形势主导,也与金融机构特别是银行跨国经营存在密切联系。赔款的经济影响不仅取决于偿付总量,也取决于经济治理能力和财税金融制度。国家财税金融制度落后,则受到冲击较大。     

How does leverage in stock market influence the margin of stock index futures?

In this article, we propose a margin-setting model under the assumption of extreme stock price changes. Specifically, extreme stock price changes are caused by the positive feedback effect of leverage and market impact. By introducing these factors into the futures price changes through a cost-of-carry model for setting the margin of stock index futures, we find that leverage and market impact in stock market are positively correlated with the margin.     

基于广义价值论的内生增长理论初探

增长理论是经济学的重要部分，关系到每一个人的福利和一个国家的地位。文章运用广义价值论研究经济增长问题，以分工为切入点，把分工产生的新增利益和该利益的公平分配统一起来，论述了递增性假设之外另一条增长的可能路径。主要结论如下：（1）基于比较优势的分工交换可以持续地产生比较利益即超过自给自足收益的净收益，这一收益不依赖于技术的递增或递减变化，具有普遍持久稳定性；（2）由分工交换产生的净收益构成原始积累的重要来源，既促进了生产规模和分工范围的扩大，又支持了研发和技术进步；（3）劳动生产力任何提高的效应都通过分工交换产生的比较利益加以放大，在一个分工交换系统中，行为主体提高比较优势产品和比较劣势产品的生产力分别具有正的和负的外部性；（4）基于广义价值论的内生经济增长体现了效率与公平的统一，一个好的制度是能够保证在交易中各方的比较利益率相等，掠夺性制度不仅直接损害经济增长，也不具备长期可持续性。     

信贷管制、隐性契约与贷款利率变相市场化——现象与解释

本文将视角聚焦于利率市场化改革之前,重点研究金融抑制对银企信贷契约的异化。研究发现,在金融抑制背景下银企之间存在以留存贷款为表现的隐性契约,用以帮助银行在满足管制要求的同时追求利润最大化。本文对这一现象进行了理论分析与实证检验,发现隐性契约的发生与否会随着货币政策、企业特征等因素的改变而有所差异,这在一定程度上起到了利率变相市场化的作用。进一步研究则发现,这一隐性契约对企业价值产生了负向影响。     

The effects of capacity reduction policy under the interest rate peg in China

Capacity reduction has been a recurrent theme in China's economic policy. The central government takes various administrative measures to remove excess capacity, accumulated mainly due to underpriced production factors and distorted incentives. I evaluate the de-capacity policy in a series of models and prove that its effects depend critically on its persistence and monetary policy regime. Under an interest rate peg, a transient policy that changes markup temporarily is ineffective and even expansionary, whereas a persistent policy is effective due to a negative wealth effect. A permanent de-capacity policy can lead to over-reactions in macro variables because the interest rate peg adds positive feedback to the economy. Therefore, the de-capacity policy has greater uncertainty under the interest rate peg. As a policy tool, it easily deviates from its target and brings about excessive volatility. However, long-run price stability and a gradually advanced de-capacity policy are conducive to the achievement of policy targets.     

The price discovery role of day traders in futures market: Evidence from different types of day traders

Using proprietary account-level transaction data in the futures market where day traders are self-declared ex ante, this study investigates whether day traders enhance price discovery at the market level. From a natural classification of day traders, we find that heterogeneous day traders have differential effects on price discovery. Self-declared day traders, who benefit from low margin requirement, do not improve price discovery measured by information share. In contrast, non-declared traders, who are not self-declared as day traders, improve price discovery. Their positive impacts on price discovery are particularly significant during periods of high volatility and arrival of new information. Overall, a margin stimulating policy may encourage more day trading, but may also attract overconfident investors, especially inexperienced ones, and who do not enhance price discovery.     

中国货币政策利率传导效率研究:2008-2017

随着利率市场化进程的不断推进以及商业银行利率定价机制的发展,中国货币政策利率的传导效率也不断提高。基于2008年1月-2017年6月的宏观时间序列数据和微观调研数据,本文检验了中国货币政策利率对银行贷款利率的传导效率。总体而言,基准利率是影响金融机构贷款加权平均利率的主要因素。分时间段看,贷款利率浮动限制放开之后,货币市场利率对金融机构贷款利率的传导效率显著提升;基准利率对金融机构贷款利率的影响略有下降,但仍然占主导。对商业银行贷款利率定价的微观机制进行探讨后,本文发现贷款利率定价机制的变化是中国利率传导效率出现变化的主要原因。进一步的分析表明,资金来源和市场利率波动均是影响货币市场利率传导效率的重要因素。最后,本文就如何提高货币政策利率传导效率提出了政策建议。本文研究对完善价格型货币政策体系以及中国货币政策框架转型具有重要的实践意义。     

Time-frequency co-movements between oil prices and interest rates: Evidence from a wavelet-based approach

This paper investigates time–frequency co-movements between crude oil prices and interest rates. To test this relationship, the study applied a continuous wavelet and cross wavelet approaches to data from West Texas Intermediate (WTI) crude oil prices and interest rates in the United States (U.S.). Results from the sample period revealed significant relationships, in the intermediate term, between WTI crude oil prices and U.S. interest rates. Moreover, co-movements between oil price and interest rate variables were especially sensitive during abnormal political events and periods of financial ‘meltdown’. We further use Partial Wavelet Coherence (PWC) and Multiple Wavelet Coherence (MWC) methods to investigate the impacts of five major control variables namely GDP growth, unemployment, three-month Treasury bill, CPI index and industrial production index. The results show a powerful impact of control variables on oil-interest rates co-movements under different frequencies. Finally, we show evidence of co-integrating long run relationship between oil markets and control variables. These results have important implications for energy investors and policy makers.
