数字资产核算与管理相关问题探析

数字经济是数字产业的时代背景，数字产业的兴盛是数字经济区别于其他时代的最显著特征。数字资产包括但不限于数据资产，数字化的数据可以成为数字资产，但数字资产的范围更广。数字资产具有无实物形态、不能独立发挥作用、可以无限复制、成本与数量无关、价值极不确定、收益可能大大偏离成本等特征。数字资产的确认、计量、信息披露缺少企业会计准则的指引，只能在实务中进行摸索。     

我国数字贸易面临的挑战及对策

当前,互联网引领数字经济将传统部门逐步数字化,不断创造新的商业模式。全球贸易正在经历数字贸易的引领和驱动。数字贸易由服务业逐步向制造业扩展,迈向数字化和智能化。数字贸易是制度创新建规则、管理创新建平台、技术创新数字化三维驱动下,将数字化的贸易内容一站式便利贸易的新型业态。"21世纪数字丝绸之路"建设、5G商用、《二十国集团数字经济发展与合作倡议》及强大的互联网市场、庞大的电商市场,为我国数字贸易发展提供了大好机遇,同时也面临着制度创新、管理创新、技术创新三大挑战。我国在数字贸易实践中,应充分借鉴发达国家的经验,利用好国际合作平台,通过多边谈判形成数字贸易规则;结合实际尽快制定管理政策,在政策引导下细分管理措施,强化数字贸易平台管理,反对平台垄断,对中小平台进行柔性管理,鼓励有实力的平台进行协同创新,突破管理瓶颈,创新实现智能化管理;技术创新主要解决数字产业化、产业数字化问题。

置身数字时代 如何打点好你的数字资产

一个亲人的离去往往令人难受。但是对于现代人来讲，一个亲人去世带来的，很可能不仅仅是难过，还可能带来很多不必要的麻烦。原因在于，我们所处的这个时代是数字时代。而给我们带来麻烦的正是数字资产。     

Competing in digital ecosystems

Digital technologies are revolutionizing traditional interdependencies among businesses. As a result, managers have begun to recognize their business environments as digital ecosystems. For firms accustomed to framing their business environments as industries, this represents a significant shift in perspective—one that requires an understanding of fresh strategic initiatives necessary to compete in the digital era. In this article, we highlight what is new and different about digital ecosystems for firm strategy. We offer frameworks that explain how digital ecosystems provide firms with new sources of value and new avenues for growth. Two sets of underlying concepts govern these frameworks: (1) production and consumption ecosystems and (2) digital envelopes and product-in-use information. We introduce and elaborate upon these foundational concepts and highlight new strategic options for firms to compete in digital ecosystems.     

数字中频接收机的设计与实现

数字中频接收机(DIFR)是对中频信号直接采样，其信道化功能由数字正交下变频器和数字滤波器来实现。因此，DIFR适用于接收和处理多载波、多模式信号，可解决很多种信号之间的互通互连问题。本文基于DIFR对动态范围、带宽、自动增益控制和高速信号采集等技术需求，优化设计了一种大动态宽带DIFR，给出了该系统的实现方案、各部分的参数分配及系统设计指标；给出了一种新型的数字自动增益控制(DAGC)实现电路，并提出了其控制算法。

Digital product innovations for the greater good and digital marketing innovations in communications and channels: Evolution,emerging issues,and future research directions

During the past quarter-century, digital technologies-based innovations for creating, communicating, and delivering products of value to customers have significantly risen in importance to the competitiveness of firms. Digital technologies-based innovations have been transformational in numerous ways, such as their impact on firms’ marketing behaviors, consumers’ search and buying behaviors, and the structural characteristics of markets and industries. Against this backdrop, this article provides a perspective on the evolution of research and practice in digital product innovations and digital marketing innovations. Specifically, the article focuses on (a) innovations for the greater good in the domain of the former and (b) direct and mediated communications through social media platforms and omnichannel marketing in the domain of the latter. In respect of each of the above, the article provides an overview of the evolution and current state of the field, highlights certain current issues and the trajectory of the field, and proposes directions for future research.     

Digital marketing and social media: Why bother?

Changes in consumer behavior require firms to rethink their marketing strategies in the digital domain. Currently, a significant portion of the associated research is focused more on the customer than on the firm. To redress this shortcoming, this study adopts the perspective of the firm to facilitate an understanding of digital marketing and social media usage as well as its benefits and inhibitors. The second generation of Internet-based applications enhances marketing efforts by allowing firms to implement innovative forms of communication and co-create content with their customers. Based on a survey of marketing managers, this article shows that firms face internal and external pressures to adopt a digital presence in social media platforms. Firms’ digital marketing engagement can be categorized according to perceived benefits and digital marketing usage. To improve digital marketing engagement, marketers must focus on relationship-based interactions with their customers. This article demonstrates how some firms are already accomplishing just that.     

Substitution or Promotion? The Impact of Price Discounts on Cross-Channel Sales of Digital Movies

Technology is transforming the marketing function in many ways, and this transformation is particularly apparent for information goods such as movies where digital technologies provide marketers with new distribution channels, which in turn create new opportunities for cross-channel effects. However, these digital channels also provide researchers with new opportunities to measure micro-level customer behavior to understand the impact of cross-channel effects in real-world settings.In this paper, we study cross-channel effects between movies sold in digital purchase (commonly known as Electronic Sell Through or EST) and digital rental (commonly known as Video-On-Demand or VOD) markets. We do this using a unique sales dataset from a major digital movie retailer provided by a major movie studio. Our analysis takes advantage of a 14-week field experiment that allows us to measure the impact of price discounts on own- and cross-channel sales. We use this experiment to estimate own and cross price elasticities, whether price discounts cannibalize future sales, and most importantly whether price discounts in one channel affect sales for the same product in a presumably competing channel.Our analysis indicates that digital movie consumers are highly sensitive to price promotions. However, we also find that, contrary to expectations, price promotions in a digital sales channel for a movie do not seem to cannibalize digital rentals. Indeed, our results suggest that, if anything, price promotions for digital movie sales can increase digital rentals. We explore a variety of explanations for this counterintuitive result, including the possibility that the ease of information transmission online through third-party websites, blogs, and online discussion areas may create information spillovers such that price discounts in one channel may increase product awareness in other competing sales channels. From a managerial perspective, our results suggest that cross-channel cannibalization can be reduced or even reversed in the presence of information spillovers, and that there are many new opportunities for marketers to directly measure these cross-channel effects using experimental data from online platforms.
