新发展格局下的全国统一大市场建设

百年变局叠加世纪疫情，我国经济发展面临"需求收缩、供给冲击、预期转弱"三重压力，建设全国统一大市场是构建国内国际双循环新发展格局的基础支撑和内在要求。文章利用相对价格方差均值方法测度了全国商品市场、劳动力市场、资本市场的一体化程度，发现商品市场一体化程度在逐渐上升，但劳动力市场、资本市场并未呈同样上升趋势。地方竞争导致的地方保护和分割负面现象、要素市场流动管制行政色彩较重、基础设施缺乏互联互通、疫情冲击是造成我国现在市场分割的直接原因。强化市场在资源配置中起决定性作用，是建设全国统一大市场的政策内涵。当前，建设全国统一大市场要以供给侧结构性改革为主线，为市场提供统一的基础性制度供给，统筹好安全和发展、全国和地方、市场和政府之间的关系，充分发挥单一超大规模市场的优势，形成以国内大循环为主体、国内国际双循环相互促进的新发展格局。     

Carbon capture and storage investment strategy towards the dual carbon goals

This paper develops a real option model combined with the Monte Carlo simulation to analyze the impact of the “dual carbon goals” on the CCS investment timing in China. The trajectory of CO₂ prices is predicted to follow a geometric Brownian motion with jump. The CO₂ prices are predicted on the basis of three scenarios: high, medium, and low shocks, respectively. Furthermore, the real option method is adopted to derive the appropriate incentive schemes and corresponding target CO₂ prices that sustain CCS operations to assist China’s dual carbon goals. Notably, portfolios of two government incentive policies are compared, including clean electricity tariff and carbon tax. The results show that building an efficient national carbon emissions trading scheme (ETS) is crucial to catalyzing the deployment of CCS technology, shortening the waiting time of CCS investment to 5.9 years at best. Government incentives could further bring the threshold CO₂ prices down and the expected waiting time of CCS investment forward.     

外资开放、市场分割与产业升级——基于双循环新发展格局视角的探讨

文章首先通过定量识别《外商投资产业指导目录》，构造出我国外资开放度指标，然后，采用价格法测算了我国省际地区市场分割程度，同时借助贸易增加值核算框架测度了我国各省市制造业细分行业的产业升级；在此基础上，将交互模型与非线性模型相结合，实证考察了市场分割视角下外资开放对产业升级的非线性影响。研究发现：第一，外资开放与产业升级之间存在"倒U型"关系。第二，市场分割的弱化会对外资开放与产业升级之间的"倒U型"关系起到缓解，甚至翻转的作用，特别是在外资开放程度较高时，外资开放对产业升级的抑制作用会随着市场分割弱化而得以缓解，甚至转变为促进作用。换言之，我国在持续深化外资开放以推动产业升级过程中需要配合统一的大市场。第三，在解决内生性问题、替换指标、加入更多控制变量以及剔除部分样本之后，结果依然稳健。上述研究表明，构建"双循环"新发展格局是进一步推动我国产业升级，实现高质量发展的重要战略选择，而打破市场分割促进以统一大市场为基础的国内大循环的畅通是当前阶段重要的突破口。     

Data analytics in small and mid-size enterprises: Enablers and inhibitors for business value and firm performance

A critical question arises as to whether data analytics (DA) can bring value and improve organizational performance. The benefit offered by DA can be achieved only when organizations are able to direct their attention on the conditioning factors that amplify business value. At the same time, organizations should cautiously resolve the issues that dampen DA business value. This study applied resource-based view (RBV) and the dual factor concept to understand such factors within the Small and Mid-size Enterprises (SMEs) context. The results revealed that information and systems qualities were the catalysts for data analytics business value, whereas lack of understanding and concerns over data security and privacy were the most salient predictors that could prevent SMEs from realizing DA business value. Our study highlights the importance of understanding both enablers and inhibitors in IT business value research. We also offer strategies to stakeholders to help SMEs realize DA business value.     

Tracing the regional dual value chains: Measurement on the production position and evidence from China

When there is insufficient internal and external impetus for developing countries’ economy, building a domestic and international dual circulation is conducive to promoting the regional industrial growth. On the basis of regional embedded international input-output tables, this paper extends the measurement framework of production position and proposes the concept of the dual value chain, which measure production position that unifies the national and global value chains from forward and backward industrial linkages. We decompose the national and global value chains into three categories and investigate the production position characteristics of China with a multi-dimensional perspective. Consistent evidence shows that a feasible path of technological progress in optimizing the production in value chains in which technological progress plays a crucial role on the pure national value chain across the high-tech manufacturing sector, the eastern and central regions. Their posterior probabilities are 0.96, 0.21and 0.86, respectively. Moreover, the impact on the dual production is nonnegligible that the posterior probability of technological progress on the eastern and central regions is 0.40 and 0.92. In addition, the impact of the Chinese economic stimulus program and technological progress on the economic crisis has a certain moderating effect. Our proposed evaluation framework sheds new light that national value chain production can boost economic growth，and further promote the coordinated of regional industries for developing countries.     

“双循环”理论综合及其在我国的应用实践

“双循环”新发展格局的提出是中国特色社会主义政治经济学的重大理论创新,本文致力于综合国民经济循环理论演进脉络和现有马克思主义政治经济学观点的新发展格局研究,构建包括循环内容、循环机制、内外循环依存关系的双循环分析框架,并以此分析框架系统梳理我国发展实践和国内国际循环现状特征。研究发现,我国经历了封闭失衡的国内循环、国内国际循环初步发展、国际大循环驱动、做大国内循环等多个发展阶段;2008以来我国国内循环比例大幅提升,以国内大循环为主体具备实践基础,但国际循环仍是重要牵引力,促进循环的创新动力和需求动力不足,国内国际循环的主导关系仍有待转换。因此,构建“双循环”新发展格局,关键是通过改革破除堵点,强化创新和扩大内需双向发力,以国内引力场集聚全球要素资源,形成以我为主、内外协同的国内国际循环互动新格局。

The impact of supermarket credibility on purchase intention of novel food

How do consumers make purchase decisions for novel food products? This research demonstrates the importance of supermarket credibility as a heuristic cue influencing consumers’ purchase decisions. We used a 2 (supermarket type: specialty store vs. conventional store) x 2 (food familiarity: novel vs. familiar) x 3 (price: high, average, low) between-subjects design and found that perceived supermarket credibility positively and indirectly mediates the relationship between supermarket type and purchase intention, and this effect is moderated by the interaction of familiarity and price level, suggesting a moderated-moderated-mediation effect. Specifically, the three-way interaction effect on purchase intention is stronger when the price is low in the familiar food condition, while the effect is stronger when the price is high in the novel food condition. In other words, consumers rely on supermarket credibility when buying novel foods, and when risk is higher people rely more on product credibility signaled by price.     

营商环境对中国省域经济高质量发展的非线性影响——双元创新的调节效应

从市场化、便利化、法治化和国际化4个维度出发，构建我国省域层面营商环境评价指标体系，采用2012-2019年中国省际面板数据，实证检验营商环境对中国经济高质量发展的非线性影响，探讨双元创新的调节效应。研究表明：①营商环境对经济高质量发展具有非线性影响，二者之间呈现“先抑后扬”的U型关系，我国大多数东部省份和少数西部省份已经跨过拐点，其余省份均位于拐点左侧，中部和西部地区营商环境水平有待提升；②双元创新对营商环境与经济高质量发展U型关系起正向调节作用。当探索式创新水平较高时，U型曲线变得更陡峭且拐点会提前出现；当利用式创新水平较高时，U型曲线变得更陡峭且拐点会延迟出现。另外，替换双元创新测度指标对营商环境不同维度进行稳健性检验也得出类似结论。
