This paper examines the spatial patterns of China's industrial encouragement policy and its distributional impact on firm productivity. To this end, I develop separate proxies to measure three popular policy instruments (subsidies, tax holidays, and preferential access to loans). I first show that China's industrial support policies tend to exhibit a prominent spatial feature of targeting firms located in lagging cities with lower density. Taking into account potential endogeneity of industrial policy, unobserved heterogeneity and firm dynamics, quantile regression techniques show that more intense industrial support leads to: (a) a reduction in the productivity of lower-performing firms, especially in denser cities; and (b) a small productivity gain for better performing firms but only in denser cities. Counterfactual analysis further reveals that pursuing an alternative, space-neutral industrial encouragement policy would increase average productivity by 14–16%, in aggregate, but also contribute to significantly higher regional inequality. 相似文献

The foreign policy crises that the USA has confronted under the administration of President Barack Obama have generated profound uncertainty about whether the USA can maintain what has been its consistent grand strategy since the end of the Cold War: primacy. The authors argue, drawing on a neoclassical realist framework, that this uncertainty has been driven not so much by fundamental changes in the international system itself, but rather by how such changes have been interpreted by the Obama administration and its critics. US grand strategy is now caught between approaches best described as the ‘decline management’ of the Obama administration and the ‘decline denial’ of president Donald Trump, which reflects the fracturing of the domestic ‘political support system’ that has underpinned primacy since the end of the Cold War. 相似文献

Excavations undertaken in 1951 at the Jaketown site revealed a dense deposit of fragmented and intact pyramid-shaped baked-clay objects (BCOs) at the base of Mound A. This deposit was associated with the site’s Early Woodland component. Recent fieldwork at Jaketown also encountered the same tetrahedron deposit and identified an additional and distinct pit feature filled with the objects. In this article, we present the results of analyses that examine the production, composition, chronology, and function of these enigmatic baked-clay artifacts. Following a hiatus associated with massive flooding in the Mississippi Valley ca. 3200–2850 cal B.P., Jaketown was re-occupied by people who shared ceramic affinities with groups to the south and to the east and, who like many contemporaries, used BCOs as a part of their cooking technology. The tetrahedron deposit represents one of the earliest dated Tchula contexts at ca. 2600 cal B.P., and was used over a short time for a social purpose that brought populations together for food consumption as a means of encouraging cooperation. 相似文献

This article examines the representation of the pilgrim in the corpus of St. Christopher dramas of early and early modern Iberia. The importance of the character's supporting role varies according to the era in which each play is written. At first, in the medieval religious dramas of the Crown of Aragon, the pilgrim not only celebrates St. Christopher's piety and anticipates his meeting with Jesus Christ, but also embodies the sanctity and devotion necessitated of pilgrimage. The pilgrims undergo a transformation in the sixteenth century as they become comic and serve as foils to the protagonist's gravity. On the seventeenth-century secular stage, the representations diverge: they begin with a traditional representation of the pilgrim, but then the figure ultimately disappears as the comedias focus on the later period of St. Christopher's life, the result of a Tridentine directive that refocused the general worship of saints and hagiographical literature. 相似文献

This paper provides a long-run analysis of the scope and profile of government in Australia using the indicator of ministerial portfolios. By scope we refer to the range and intensity of government activity. By profile we refer to the balance of three categories of activity (defining, physical resource mobilisation and social). Although there has been growth in the scope of government in the twentieth century, the rates of change have varied over time, by level of government and by category of activity. Whilst the intensity of government has decreased recently, its range has not. Government has not evacuated areas it once occupied. Because the three categories of activity have grown at different rates, the overall profile of government has changed. We explain the extent to which the increase in government scope has been a function of the undertaking of new responsibilities as opposed to an intensification of existing ones. 相似文献

Abstract. Central to assertions of national identity in the contemporary world is a sense of collective mission and destiny. This is clearly manifest in the recent spate of religious nationalisms, but it is also present as a component of secular nationalisms. In both cases, it is possible to trace the origins of the sense of collective destiny to much earlier beliefs in ethnic chosenness. In some cases a strict ‘covenantal’ form of the myth of ethnic election, such as was found in the Old Testament, has survived more or less intact into the modern era. In many other instances, a looser sense of ethnic election by the deity has continued to influence the outlook and purposes of secular nations. While there is no strict covariance between the earlier myths and modem national ideals, the ancient beliefs in divine election have given modern nationalisms a powerful impetus and model, particularly among peoples in the monotheistic traditions. 相似文献
