Strategic Network Orchestration in Emerging Markets: China's Catch‐up in the High‐Speed Train Industry

Transitioning from catch‐up in production to catch‐up in innovation capabilities is essential to emerging market firms (EMFs) achieving internationalization and a competitive advantage. While some EMFs are now positioned among the world's most advanced firms, many struggle to become independent innovators. Thus, understanding how EMFs can develop internal absorptive capacity and progress towards catching up in innovation capabilities remains important. Our study seizes this research opportunity and develops a network‐based explanation of catch‐up, which complements existing technological and organizational explanations. Specifically, we address the question of ‘How does the orchestration of collaborative networks enable EMFs to catch up in production and innovation capabilities?’ by describing an important yet under‐researched process of strategic network orchestration and showcasing the dynamic interdependencies between network orchestration and organizational learning. Our study provides a detailed account of Chinese high‐speed train (HST) development from 1990 to 2020 and opens the possibility for future research on network orchestration in emerging market contexts. This provides EMF managers with a set of actionable network orchestration mechanisms that can be used when designing and purposefully managing their strategic nets of domestic and foreign partners.     

启蒙与马克思主义中国化

新文化运动后期,因马克思主义的传入而使中国历史的命运发生了改变,从此马克思主义与启蒙便产生了复杂的关系。文章从思想史的角度出发,围绕中国启蒙思想的递嬗轨迹和特殊内涵,深入分析启蒙与马克思主义中国化互相影响的特殊过程,揭示不同的历史发展阶段启蒙与马克思主义的历史关系,重新审视启蒙与中国的特殊国情。在中国社会转型期的当下,凸显启蒙对中国现代化建设的重要现实意义。     

IPO 募资双重管制与资源配置——基于自然实验的经验证据

本文探讨我国首发市场中针对募集资金的两种管制政策的交互效应对资源配置的影响.研究结果发现,募资用途和募资额度管制的交互作用会导致募资不足,从而加大公司上市后融资约束的程度,进而引起投资不足. 2009年放开募资额度管制后,公司的融资约束得到缓解,但持有过量的超募资金又会引发过度投资.进一步研究发现,企业持有的超募资金与其长期绩效呈倒U型关系.本文的研究结论对目前处于酝酿中的IPO注册制的相关政策制定和制度设计具有参考意义.     

Linear scalar-on-surface random effects regression models

Many research fields increasingly involve analyzing data of a complex structure. Models investigating the dependence of a response on a predictor have moved beyond the ordinary scalar-on-vector regression. We propose a regression model for a scalar response and a surface (or a bivariate function) predictor. The predictor has a random component and the regression model falls in the framework of linear random effects models. We estimate the model parameters via maximizing the log-likelihood with the ECME (Expectation/Conditional Maximization Either) algorithm. We use the approach to analyze a data set where the response is the neuroticism score and the predictor is the resting-state brain function image. In the simulations we tried, the approach has better performance than two other approaches, a functional principal component regression approach and a smooth scalar-on-image regression approach.     

区块链技术下智能合约之于合同的新诠释

应用于交易领域的智能合约融入区块链技术,以代码形式表现,可实现合同履行的自动化和不可逆,超越了传统意义上的合同模式.自助行为说、代理说将智能合约视为对合同过程的外部增强,是侧面功能的法律阐释,并未完全捕捉到实质.智能合约并不一定跨越整个合同过程,也可仅是合同过程某个方面或某个阶段.法律意义上的智能合约不是合同新类型,而是合同关系形式的新发展,即当事人缔结和履行合同的新形式,合同性质未发生实质变化.智能合约满足特定要件构成特殊的书面形式,具有"书面形式+自动履行"功能的特质.民事主体通过智能合约形式订立合同应遵守《民法典》等现行法律的具体规则,以保证合同依法成立与生效.智能合约不等同于具有法律效力的合同,认定其效力应结合智能合约应用中的具体问题展开具体分析.从立法上确认智能合约,在符合国家现有法律、政策基础上编写和应用,实现形式的合法化、内容的规范化是该技术谋求长远发展的保障.技术起步的现阶段,纸质合同、一般电子合同与智能合约在不同方面发挥协作作用,会在未来一段时间内成为民事交往、商业交易的主要状态.     

地方政府重大决策机制存在问题及优化路径

地方政府作为地方公共事务管理者，决策正确与否直接关系到公共管理活动的成败，并且在一定程度上影响地方经济发展的水平及其核心竞争力。由于我国地方政府现阶段决策主体多元性及其职能模糊性，一些重大决策失误现象屡屡发生，造成了有限资源的巨大浪费，严重影响了地方政府在人民群众中的威信和形象。对此，我国地方政府迫切需要优化重大决策机制，包括明晰体制内外决策主体的职能、第三方评估、公众参与、决策终身责任追究及倒查机制等，以推进地方政府决策的民主化、科学化和法治化。     

Inferences for a Partially Varying Coefficient Model With Endogenous Regressors

In this article, we propose a new class of semiparametric instrumental variable models with partially varying coefficients, in which the structural function has a partially linear form and the impact of endogenous structural variables can vary over different levels of some exogenous variables. We propose a three-step estimation procedure to estimate both functional and constant coefficients. The consistency and asymptotic normality of these proposed estimators are established. Moreover, a generalized F-test is developed to test whether the functional coefficients are of particular parametric forms with some underlying economic intuitions, and furthermore, the limiting distribution of the proposed generalized F-test statistic under the null hypothesis is established. Finally, we illustrate the finite sample performance of our approach with simulations and two real data examples in economics.
