How plant competition varies across environmental gradients has been a long debate among ecologists. We conducted a growth chamber experiment to determine the intensity and importance of competition for plants grown in changed environmental conditions. Festuca rubra and Trifolium pratense were grown in monoculture and in two- and/or three- species mixtures under three environmental treatments. The measured competitive variations in terms of growth (height and biomass) were species-dependent. Competition intensity for Festuca increased with decreased productivity, whilst competition importance displayed a humpback response. However, significant response was detected in neither competition intensity nor importance for Trifolium. Intensity and importance of competition followed different response patterns, suggesting that they may not be correlated along an environmental gradient. The biological and physiological variables of plants play an important role to determine the interspecific competition associated with competition intensity and importance. However, the competitive feature can be modified by multiple environmental changes which may increase or hinder how competitive a plant is. 展开更多

This paper examines the optimal forecast-sharing strategy in a hybrid-format online platform supply chain where a supplier sells a product through agency format and reselling format provided by a platform retailer who possesses demand forecasts from two channels.Forecast asymmetry and co-opetitive relationship arise between the platform retailer and the supplier,which affect their operational decisions and the supply chain’s performance.To improve supply chain efficiency,we compare different forecast-sharing strategies(i.e.,no forecast sharing,sharing a single forecast,and sharing two forecasts),and analyze the effects of co-opetitive parameters on the optimal forecast-sharing strategy.Our analysis shows that forecast sharing is always beneficial to the supplier,and sharing two forecasts is more beneficial than sharing a single forecast.Whereas for the platform retailer and the whole supply chain,forecast sharing is beneficial only under certain conditions,depending on the co-opetitive parameters.The optimal forecast-sharing strategy is the result of a combination of the negative effect of double marginalization in reselling channel and the positive effect of responding pricing to demand uncertainty in agency channel.We illustrate the parameter regions of the platform retailer’s voluntary sharing,contract sharing,and no sharing,and also find that higher channel competition intensity,higher market share of agency channel,and higher commission rate can promote the platform retailer’s voluntary sharing.Our study extends the research scope of demand forecast-sharing and sheds light on the decision-making processes for managing a hybrid-format online platform supply chain. 展开更多

The land price in big cities draws much attention and discussion for its skyrocketing appreciation.Most researches are from the macro perspective due to data restriction.This paper aims to investigate the critical factors in the price formation process of a land auction,using the listing auction micro bidding-level data in Beijing from 2013 to 2018.We construct a model for the relationship between quitting price and land,bidder's characteristics,housing market conditions and competitive intensity(including private and public signals),then we use OLS for identification.We find that competitive intensity increases the quitting price by causing competition and interaction between bidders.More importantly,we find evidence of cheating behavior in the land market.Results show that bidders have higher quitting prices when they are in a joint venture,and when a central SOE developer or a top 10 developer exist in the joint venture.We also find different behavior of developers in the short run and long run.Our research contributes to the literature of land auctions by analyzing the price formation process and developers'behavior.We also provide supporting evidence for the government to make adjustments of the auction system and identify the cheating developers. 展开更多

Aims Populus deltoides and P.euramericana are widely used in China as major forestry species.At present,little is known about their responses to nitrogen(N)deficiency when grown in monocultures or mixed plantations.The aim of this investigation was to analyze the growth,and morphological and physiological responses of P.deltoides and P.euramericana to different N levels under competition conditions.Methods We employed two Populus species(P.deltoides and P.euramericana)to discover how N deficiency affects plant traits under different competition types(P.deltoides×P.deltoides,intraspecific competition;P.euramericana×P.euramericana,intraspecific competition;P.deltoides×P.euramericana,interspecific competition).Potted seedlings were exposed to two N levels(normal N,N deficiency),and nitrogen-and competition-driven differences in growth,morphology and physiology were examined.Important Findings Under normal N conditions,interspecific competition significantly decreased the total root weight,root mass fraction(RMF),root–shoot ratio(R/S)and carbon/nitrogen ratio(C/N),and increased the leaf dry weight,leaf mass fraction and total leaf area of P.euramericana compared with intraspecific competition.The same conditions significantly affected the growth and morphological variables of P.deltoides,except for the dry weight of fine roots,R/S,specific leaf area,RMF,total nitrogen content and C/N compared with intraspecific competition.In addition,chlorophyll a(Chla),total chlorophyll(Tchl),carotenoid contents(Caro)and the carbon isotope composition(δ13C)of P.deltoides were significantly lower in interspecific competition than in intraspecific competition,but no difference was detected in P.euramericana.The effects of N deficiency on P.deltoides under intraspecific competition were stronger than under interspecific competition.In contrast,the effects of N deficiency on P.euramericana between intraspecific and interspecific competition were not significantly different.These results suggest that under normal N condition,P.deltoides is expected to gain an advantage in monocultures rather than in mixtures with P.euramericana.Under N deficiency,the growth performance of P.euramericana was more stable than that of P.deltoides under both cultivation modes. 展开更多

Although entrepreneurial orientation has been identified as a key facilitator of a firm's innovative behaviors, its antecedents, especially the determinant role of the business leader, have yet to be explored. Drawing on strategic leadership theory, which posits the role of CEO in determining a firm's strategic direction, we examined the influence of CEO demography, specifically age, tenure, and education, on a firm's entrepreneurial orientation. Based on a sample of 231 Chinese firms, we found firms with a CEO who was younger, higher educated, and with a shorter tenure on the job had a greater extent of entrepreneurial orientation. Moreover, the firm's competitive environment moderated these relationships. 展开更多

Based on the global patents of 109 mobile phone vendors filed from 1992 to 2016 and sales data from 2002to 2016, this study formulates technological and market competition networks. We find that an increasingly large number of firms joined the market, leading to a competition network of increasingly larger scale and greater density. We also propose indicators to measure competitive intensity, which reflects the extent to which the firms are competing against each other. We examine the role of competitive intensity in mediating firms’ performance. We employ a weighted least squares regression model for the empirical analysis. The empirical results confirm the significant role of competitive intensity in determining firm performance. However, in technological and market competition networks, competitive intensity generates essentially different mediating impacts. For technological competition, competitive intensity positively mediates the impact between the leaders’ and followers’ technological performances. There is an asymmetric mediating effect that enlarges the gap between the technological performances of leading vendors and their followers. Accordingly, competitive intensity may generate different impacts on the technological performance of leaders and followers. In comparison, the competitive intensity embedded in the market competition network has a symmetrical role in mediating the mutual impact between the leaders’ and followers’ market performances, that is, it neither enlarges nor narrows the market performance gap between leaders and followers. Therefore, when creating a development strategy, firm managers need to account for their competitors’ behaviors, carefully analyze the significance of these behaviors, and adjust their strategic arrangements in a timely manner. 展开更多

Drought can affect the growth and soil enzyme activities of invasive alien plants(IAPs).It is imperative to evaluate the competitive advantage of IAPs compared with that of the native species and the activities of soil enzymes under drought.This study aimed to evaluate the competitive advantage of the IAP Amaranthus spinosus that originated from tropical America compared with the native Chinese species A.tricolor and the activities of soil enzymes under drought.A competitive co-culture of A.spinosus and A.tricolor was established using a planting basin experiment.The two species were treated with different levels of drought,i.e.(i)the control;(ii)a light level of drought and(iii)a heavy level of drought.The functional traits,osmotic adjustment and the activities of antioxidant enzymes of the two species,as well as soil pH and electrical conductivity,contents of soil microbial biomass carbon and the activities of soil enzymes were determined.The relative competition intensity and relative dominance of A.spinosus were greater than those of A.tricolor under drought.Drought may provide an advantage to the competitive advantage of A.spinosus.Soil water-soluble salt content and sucrose hydrolytic power of A.spinosus were greater than those of A.tricolor under drought.The ability of A.spinosus to grow in soil with higher levels of water-soluble salt contents and sucrose hydrolytic power under drought may aid in its acquisition and utilization of nutrients. 展开更多
