This paper examines the impact of economic and development zones (EDZs) on the productivity of incumbent firms in China. To deal with the selection issue, I first take into account potentially different selection mechanisms across two popular types of EDZs—economic and technological development zones (ETDZs) and high‐tech development zones (HTDZs)—by relying on multiple treatment propensity scores matching techniques. Next, I apply the difference‐in‐differences estimator to the matched sample and conduct an event study analysis. The results show that the respective effects of ETDZs and HTDZs on firm productivity are positive, but subject to a nonlinear trend over time. The size of the productivity gains depends critically on the type of EDZ, however. A new HTDZ (ETDZ) leads to an average productivity gain of up to 30.2% (18.4%) for incumbent firms in the 5 years after the zone was created. These findings suggest that the size of productivity spillovers for spatially targeted firms differ quite significantly depending on the strategic development and policy goals of the EDZ: HTDZs that focus on promoting indigenous‐based factors of learning lead to higher productivity spillovers compared with ETDZs that focus on promoting extra‐local linkages. 相似文献

Gentrification in China, as in any other contexts, is an innate process embedded in the dynamic urban metamorphosis, thus requires a provincialised lens to understand its ‘home grown’ mechanism and periodisation, while not losing sight of the macro politico‐economic changes. Hence I propose an analytical framework of ‘state‐centred triangular embedment’ to enable a holistic yet nuanced examination of the delicate entanglements of the state, market and society amidst the surging waves of gentrification in China: The first wave of sporadic gentrification in the 1990s, the second wave of widespread gentrification in the 2000s, and the third wave of reactivated gentrification under state‐led financialisation after 2010. Gentrification has become an integral part of the making of the modern competitive state in China, joining force with the state’s endeavour in extracting values from land/housing redevelopment through market operation, imposing modern (western) values to its society while intermittently responding to social contestations. 相似文献

In recent years, the bioeconomy has emerged as a key policy idea in liberal western states. This paper analyses the bioeconomy as a state strategy. By building on theoretical strands by Poulantzas, Moore, and Castán Broto, the paper argues that the bioeconomy has to be understood simultaneously as an accumulation strategy within the capitalist world‐ecology and as a transformative agenda through which tensions in the state space can be governed. The politics of bioeconomy do not concern its outright endorsement or rejection but the ways its contradictions are interpreted and articulated. The empirical part of the paper scrutinises the bioeconomy strategy adopted in Finland. Our main concern is that the bioeconomy strategy has been appropriated by the traditional forest industries in such a way that fails to address the problem of uneven development and ignores the potential of the bioeconomy as part of a transformative agenda. 相似文献

This study examines evidence for change in adze form and raw materials in the Auckland (Tamaki) region using a sample of 144 adzes from 11 securely dated assemblages spanning the pre‐European Maori sequence. Non‐destructive portable X‐ray fluorescence geochemical analyses indicate that the assemblages were dominated by two stone sources throughout the sequence; locally available Motutapu greywacke, and Tahanga basalt from the Coromandel Peninsula some 100 km distant. Additional analyses, incorporating adze form and use‐life data, indicate that both materials were used in a similar manner. The results of this study suggest that, although patterns of change argued for in existing models of New Zealand's prehistory provide a broad overview of general trends, targeted studies also are required to identify regional variation. 相似文献

Ground‐penetrating radar (GPR) and magnetic surveys were conducted on 13 earth mounds within Mapoon Aboriginal Lands, western Cape York Peninsula, Queensland. Detailed analysis of GPR profiles and amplitude maps of the mounds were compared to those from previously recorded, known burials at the Mapoon Mission Cemetery. Based on these models, burials were identified in ten of the 13 mounds. Both European‐style (coffin) and traditional burials were identified, suggesting that they were used for human interment for some time and that there may have been continuity of burial practice in these features after European contact. GPR and magnetics also indicate that a number of mounds had constructed floors or platforms at the base of the mounds, and evidence for burning. Stratigraphic layers identified with GPR show that many of these mounds have complex internal layering, suggesting multiple building episodes. Based on the GPR and magnetics results, in conjunction with ethnohistorical and oral history research, we conclude that the mounds are constructed features that appear to have had a long history of use for multiple purposes, including mortuary. These results demonstrate the cultural continuity of mortuary practices within Mapoon from pre‐contact times to the present. 相似文献

This special section examines the possibility of meaningful debate and contestation over urban decisions and futures in politically constrained contexts. In doing so, it moves with the post‐political times: critically examining the proliferation of deliberative mechanisms; identifying the informal assemblages of diverse actors taking on new roles in urban socio‐spatial justice; and illuminating the spaces where informal and formal planning processes meet. These questions are particularly pertinent for understanding the processes shaping Australian cities and public participation today. 相似文献

A coated Roman iron coin from Villa Loig in Salzburg, Austria was investigated. The coating is a copper alloy consisting of Cu, Pb, Sn, Zn and negligible amounts of Ag, a variant of gunmetal known as ‘leaded red brass’. The numismatic term for such a coin is subferratus (Latin). From an archaeometallurgical point of view, information about the chemical composition, the microstructure and the manufacturing technique are of interest. To achieve these objectives, different analytical techniques and metallographic examinations were applied. Droplet‐shaped iron inclusions were observed in the red brass coating, while at the grain boundaries, inside the iron core, copper and lead were detected (liquid metal embrittlement). The dendritic microstructure of the coating, the spheroidal‐shaped iron inclusions in the coating and the liquid metal embrittlement show that the iron coin was plated by immersing it in a molten copper alloy. The iron core is a low‐carbon steel with slag stringers, both of which are characteristic of a bloomery iron. Deformation twins (Neumann lines) were observed in the microstructure of the iron core and indicate that the coining was performed after the flan was cooled. 相似文献

A group of 18 cameos dated from the 16th to 19th centuries (bearing motifs of Roman emperors and female members of their families) from the Constantine Schmidt‐Ci??yński collection was investigated with gemmological analyses, supported by non‐destructive mineralogical methods such as X‐ray diffraction (XRD) and micro‐Raman spectroscopy (RS) to ascertain the material used. Although there is no scientific method to date the specimens precisely, the mineralogical data supported by archaeological analyses enabled the estimation of the possible timing of the manufacture of the gems. As a result, the cameos were divided into four basic chronological groups: (1) Renaissance, (2) Baroque, (3) uncertain and (4) Classical and Neoclassical. 相似文献

Slipped and unslipped wares from Kampyr Tepe dated to the Hellenistic–Seleucid and Greco‐Bactrian periods stylistically resemble tableware from the Greek tradition. Since two pottery workshops have been recovered at the site, the aim is to shed light on the provenance and the production and consumption patterns of the tableware, as well as on the degree of technological influence from Hellenistic–Mediterranean traditions. The archaeometric characterization, consisting of thin‐section petrography, XRF, XRD and SEM–EDS analysis, was performed on 44 wares and three unfired locally made pondera, which were used as reference local elemental patterns. The study demonstrated the local origin of most of the wares, which were produced using a similar clay paste, following standardized techniques in modelling and firing, while surface treatments appear to be more diversified. 相似文献

Radiogenic lead and strontium isotope data are presented for lead‐ and calcium carbonate/barium sulphate‐containing paint and ground samples from 15 paintings, executed between 1844 and 1871, by 19th‐century Canadian artist Cornelius Krieghoff. Like many artists of this era, Krieghoff used lead‐based pigments such as lead white, chrome yellow and Naples yellow, and extenders such as calcium carbonate and barium sulphate. The lead isotope analyses of the majority of these pigments are consistent with the isotopic compositions of lead mined from European lead deposits in England and/or Germany. However, three samples from Krieghoff's early career yield lead isotope compositions that are much more radiogenic than European sources. The lead isotope compositions of these three samples are consistent with the addition of a more radiogenic lead component that is similar to the lead derived from North American lead deposits in Missouri and Illinois (Mississippi Valley Pb–Zn type deposits). The strontium isotope compositions of the extenders suggest that the raw materials for calcium carbonate or barium sulphate extenders were largely derived from Palaeozoic to modern‐day marine environments. This study shows that pigments manufactured from North American lead were being incorporated into Canadian paintings as early as 1844. 相似文献
