科学与技术耦合效果评价——科技互补效应和成本效应分析

考虑到当前创新环境日益复杂化，科学与技术耦合系统已成为一个受系统内外因共同影响而发生演化的开放系统。在为耦合系统构建状态空间模型的基础上，通过求解该模型，刻画科学技术化强度和技术科学化强度，据此分析科学与技术互动产生的互补效应和成本效应，评价29个省份的科学与技术耦合效果，并测度地区科技发展所属耦合路径类型。研究表明，不同省份推进科学技术化进程和技术科学化进程的差异性显著；科学与技术耦合效果最佳并不能说明地区科技发展速度最快；绝大多数省份的科技耦合路径表现为科技中立路径，占比最小的路径为技术强势路径。基于不同省份的耦合情况差异，提出针对性建议。     

战略与复杂双重维度下商业生态系统形成机理研究

基于战略和复杂双重维度，剖析阿里巴巴商业生态系统形成逻辑。结果发现：较强的战略控制力有利于强化平台商业模式，催生跨行业多样化平台，继而推进生态内信息化不断深入发展；随后，商业生态系统积蓄丰富的共享数据资源，打开资源交易和创造边界，提升生态主体能力的同时重塑生态系统属性；有着更强复杂应配力的生态主体不断探索商业模式创新，生态内外的创新扩散催化商业生态系统竞争，进一步强化复杂应配力。在核心企业战略控制力和生态主体复杂应配力的双重作用下，商业生态系统呈现前生态状态、生态内卷、生态扩散和生态共生4种不同状态。     

高技术产业国家价值链网络结构与省域增加值分解——来自电子信息产业的证据

为破解我国在高技术产业全球价值链中面临的低端锁定困境，需要构建并完善国家价值链分工体系。构建中国高技术产业国家价值链内生增值传导网络结构分析框架，并以电子信息产业为例，对省域国内增加值进行分解。结果表明，现阶段中国电子信息产业上游技术研发能力较弱，整体增值能力不强；下游间接关联产业部门数量及关联系数值仍待提高；除中游外，上下游出口国内增加值偏低，国际竞争力较弱；东、中部省域国内完全增加值占据优势，内生增值能力方面各有所长，东北、西部省域国内完全增加值及其内生增值能力均较弱。同时，中国省域国际垂直专业化程度未表现出显著地理地区特征，即使同一地域的省域之间也存在不同程度差异。     

Effects of price sorting display on extreme option choice aversion: The role of ease of comparison in multiple option displays

Due to the popularity of online travel agency (OTA) booking platforms, OTAs display diverse information, including features of products, on their websites. Based on choice architecture literature, this study aimed to examine the effect of product quality and price sorting (vs. non-sorting) on extreme option choice aversion and identify the moderating effect of displays that made it difficult to read information. The results of a series of four experimental studies (total n = 2838 online panel members) demonstrated that the tendency to choose the non-extreme or middle-attributed options was stronger when quality and price were displayed sorted (vs. non-sorted). It was theorized that easy comparison of multiple options leads to decision-making. The positive effect of quality and price sorting on extreme option choice aversion was significantly reduced when customers had difficulty reading the displayed information.     

China and international market integration: Evidence from the law of one price in the Middle East and Africa

We model market integration in the Middle East and Africa by analyzing price dispersion and testing the law of one price (LOP) on highly-comparable actual local retail prices of 135 goods and services across 23 countries in the region over the period of 1990–2016. Second-generation panel estimators are applied to four price benchmarks: Regional average, South Africa, China, and US prices. Cross-regional price dispersion diminishes considerably over time up to 2008, particularly for non-tradeables around China price. The test of LOP indicates the percentage of convergent prices is highest in China price benchmark, followed by US, South Africa, and regional average benchmarks. Direct estimation of the convergence speed confirms this order. Overall, the results show evidence of increasing market integration in Middle East and Africa but it appears to be driven by global forces and, especially, the rise of China as a new economic power. The results show that some emerging market economies, such as China, can step up and promote integration while traditional economic powerhouses, such as the USA and UK, disengage from international economic relations.     

对外直接投资影响我国创新能力的机制与实证研究

利用2003-2015年我国内地30个省份的省际面板数据，在概述对外直接投资影响一国创新能力作用机制的基础上，借鉴Lichtenberg和Pottelsberghe提出的国际研发溢出测算方法，从技术差距视角出发，运用面板门槛模型实证检验二者间的关系。结果显示：对外直接投资可以通过R&D成果反馈效应、并购整合效应以及产业前后向关联效应提升一国创新能力；在不同的门槛取值区间内，OFDI逆向技术溢出对创新能力提升的作用呈显著倒U型特征，只有在最优技术差距区间内才能发挥其最大效应。最后，在作用机制概述和实证研究结论基础上，从政府和企业两个层面提出政策建议。     

Antecedents of Perceived Value and Repurchase Intention of Organic Food

The rise of the natural and organic products market follows a global trend of increasing demand largely due to the growth of environmental awareness and the concern of having a healthier diet. Thus, the objective of this study is to propose and test a theoretical model based on antecedent constructs of perceived value and repurchase intention on the consumption of organic products. The results, based on 256 consumers of organic products, confirm the positive relationship between environmental awareness and perceived quality, healthy consumption, and perceived price fairness. Moreover, they underpin the influence of healthy consumption, perceived price fairness and perceived quality on perceived value, and lastly, the influence of perceived value on repurchase intention. Therefore, this study can help practitioners and consumers comprehend in a more systematic way the buying behaviour of this food category.     

颠覆性创新四阶段扩散过程模型

联结强度与技术创新模式：企业间信任的中介作用

关于合作关系对合作创新的影响，现有研究大多局限于单一的社会网络视角，对网络层次的关系特征如何通过双边层次的关系质量影响技术创新模式的过程欠缺机理性认识。结合社会网络、社会资本和知识转移理论，分析网络联结强度、企业间信任以及技术创新模式三者间关系。利用327份来自全国多地的制造及高新技术企业数据，采用结构方程模型检验方法对研究假设进行检验。结果表明：相对于经济型信任，强联结会带来更多情感型信任；情感型信任更有利于渐进式创新，经济型信任更有利于突破式创新；联结强度对渐进式创新的作用是通过情感型信任传递的，而联结强度对突破式创新的作用是通过经济型信任传递的。
