Developing technological applications, entering exploitation alliances, and choosing between research‐ or service‐focused strategic orientations are decisions that high‐tech firms must manage concurrently. This article explores systematically the contrasting effects of these strategic determinants on rent generation and rent appropriation using the entire population of French biotech firms (1994–2002). Findings indicate that science and money do not unconditionally go together–the direct relationship between rent‐accruing resources (e.g., patents or articles) and rent appropriation varies depending on the type of resources and the strategic orientation. Moreover, the effects of strategic determinants differ for rent generation vs. rent appropriation: 1) technological application diversity undermines a firm's capacity to appropriate rents–in particular for research‐oriented firms; 2) exploitation alliances favor rent generation but hinder rent appropriation; 3) service‐oriented firms exhibit significantly better performance than research‐oriented firms. Such evidence challenges the emergence in the biotechnology industry of a ‘one‐best’ strategic trajectory, as represented by research‐intensive start‐ups funded by private money engaged in publishing and patenting races.

(上接《中国农史》2020年第6期)五、湘西北澧阳平原彭头山文化的奇迹虽然整个长江中下游地区都可以被称为是新石器时代稻作发展地带,但是考古学及古环境研究表明,栽培水稻的生活方式最早产生且根深蒂固的发祥地并没有那么广大,而是以澧阳平原为核心地的彭头山文化地区。在彭头山文化之前,野生稻已进入华南地区初步定居人群的生活中;而彭头山文化晚期以来,稻作聚落多见于洞庭平原,且聚落结构趋向于稳定,遗址出土炭化的早期栽培稻种的概率非常高,并且出现萌芽形态的水田,如田块、田埂和排水沟等。也就是说,虽然人们早于彭头山文化时期就开始利用水稻,但其生活发生转折的关键期却是在彭头山文化时期。只有彭头山文化才是完全放弃狩猎,单纯依靠采集和网捕水中及水边食物维生而完全定居,并致力于稳定地发展稻作农耕的时代,是最早也是迄今所知唯一的案例。 相似文献

Social media (SM) platforms are frequently used by pre-teen (8–12-year old) consumers for curating their self-identity, developing social relationships and for learning. This paper identifies the building blocks that drive pre-teen SM engagement. We use the Gioia method to analyse interview data collected from 32 pre-teens and parents, in France. Findings show that the primary building blocks are FoMO (Fear of Missing Out) and social inclusive experience, being noticed online, multiplicity, excessive use (without guidelines) and self-regulation. Identity constructs (self-identity and social-identity) are used to explain SM engagement – and to empirically define core conceptual building blocks (aggregate dimensions) that drive SM engagement. We contribute to consumer theory by developing a holistic research framework to examine pre-teen SM engagement. Self-identity and social-identity theories help explain the factors that drive pre-teen SM engagement and explain push/pull influences of parents and schools in encouraging or discouraging certain behaviour. We build on current research into SM usage, drawing from the fragmented existing literature, to reveal causes of both excessive screen-time and SM usage among pre-teen consumers, which may indicate antecedents of future adult behaviour. Practical and regulatory policy issues are considered and addressed. 相似文献

The paper investigates two policies geared towards stimulating and shaping global value chains (GVCs), namely deep regional trade agreements (DRTAs) and bilateral investment treaties (BITs). In an augmented gravity model, we test the impact of both policies on a variety of trade in value added indicators. We find that both policies are likely to increase GVC trade, although their transmission channels differ. While backward linkages are stimulated through both BITs and DRTAs, forward linkages respond only to DRTAs. The estimates suggest that negotiating a DRTA with investment provisions has a higher impact on trade in value added than signing a shallow RTA and a separate BIT. 相似文献

Over the last 20+ years, multinational corporations (MNCs) have been confronted with accusations of abuse of market power
and unfair and unethical business conduct especially as it relates to their overseas operations and supply chain management.
These accusations include, among others, worker exploitation in terms of unfairly low wages, excessive work hours, and unsafe
work environment; pollution and contamination of air, ground water and land resources; and, undermining the ability of natural
government to protect the well-being of their citizens. MNCs have responded to these accusations by creating voluntary codes
of conduct which commit them to specific standards for addressing these issues. These codes are created at both the industry-wide
and the individual company level. Unfortunately, these codes have generated little credibility and public trust because their
compliance claims cannot be independently verified, and they lack transparency and full public disclosure. In this article,
we present a case study of the voluntary code of conduct by Mattel, Inc., the world’s largest toy company. The code, called
the Global Manufacturing Principles (GMP), confronts the general criticism leveled against voluntary codes of conduct by (a)
creating detailed standards of compliance, (b) independent external monitoring of the company’s compliance with its code of
conduct, and (c) making full, and uncensored public disclosure of the audit findings and company’s response in terms of remedial
action. We present a detailed account of how Mattel’s voluntary code of conduct was created, implemented, and ultimately abandoned
over 9 years. We provide an evaluative analysis of the company’s GMP compliance throughout its life span, which suggests a
bell-shaped curve, where early top management commitments were met with pockets of resistance from operational groups, who
were concerned about balancing GMP compliance efforts with traditional performance criteria. The early stage response from
Mattel’s top management was quick and supported with the requisite resources. As a result, the compliance process accelerated,
becoming increasingly more robust and effective. The success of code compliance and increased transparency in public disclosure
energized field managers with a sense of professional satisfaction and publicly recognized accomplishments. The decline in
GMP compliance was equally steep. When all the easily attainable targets had been reached at the company-operated plants,
addressing vendor plants’ compliance presented a new set of challenges, which taxed corporate resources and management commitment.
It would seem that value-based and ethics-oriented considerations, i.e., doing the right thing for the right reason, were
no longer the driving force for Mattel’s management. Mattel did not see any economic benefit from its proactive stance, when
competitors did not seem to suffer adverse consequences for not following suit. The final contributing factor to the code’s
abandonment was a widely publicized series of product recalls which absorbed top management’s attention. 相似文献

The threat that climate change impacts pose to rare and vulnerable destinations has given rise to a phenomenon known as last chance tourism. This travel behaviour involves tourists increasingly travelling to destinations they perceive to be critically threatened, while contributing to greenhouse gas emissions and climate change impacts in these very places. For last chance destinations to be managed effectively in the face of climate change, a clearer understanding of what drives this travel behaviour is needed. Drawing on the importance of place and nature to identity construction, this research uses a structural equation modelling approach to examine last chance tourism motivations in Churchill, Canada. Results provide evidence of a motivation to engage in a last chance experience. They also indicate that this motivation is related to a desire to share a connection to nature with similar individuals, and to become part of the local story. Beyond this, results show that visitors' sense of place identity and nature relatedness contribute significantly to their motivation to engage in last chance tourism. Findings from this research are important to the management of last chance destinations, including protected areas that are legislated to preserve significant natural and cultural features. 相似文献

This article examines residents' perceptions of sociocultural impacts in the North Cape community in Norway. Case study, as a qualitative methodology, was employed to gather the necessary data. Based on the in-depth interviews with 22 permanent residents of the North Cape community, 10 influential factors were empirically identified: source of income; quality of life; community structure; demonstration effect; crime and alcohol; acculturation; perspective; status and community pride; conflicts; and physical impact. Furthermore, in contrast to the existing theory, the current study suggests that both those who are, and who are not economically dependent on the tourism industry perceive tourism positively. Both long-term and short-term residents believe that tourism's benefits outweigh tourism's costs. No noteworthy differences are found across sociodemographic factors such as education and marital status with respect to the residents' perception. The almost overwhelmingly positive response of the residents can be attributed to the current stage of destination development cycle at the North Cape. 相似文献

In this article, we empirically investigate regional unemployment in Russia. We first detect the existence of two unemployment clubs, that is, regions with high (low) unemployment surrounded by regions with high (low) unemployment, and a group that comprises the remaining regions. We then apply a specially designed class of spatial-econometric models to regional data 2005–2012, using difference GMM, and we obtain partial confirmation of our two main hypotheses: (i) spatial effects for the high-high and low-low clubs regions differ significantly; and (ii) the determinants of unemployment of the two clubs significantly differ with respect to those of the remaining regions. Our results have key implications for the national- and regional-level policies. 相似文献
