    WHY CHINA INDUSTRIALIZED AFTER ENGLAND

    ECONOMIC INQUIRY, Issue 4 2010
    BARRY S. KAHN
    Although industrialization first occurred in England, it is thought that China, not England, may have been the world leader in technology at the time. Yet, China did not industrialize until 150 yr after England and nearly a century after less advanced European countries. This represents a puzzle because two-sector neoclassical growth models, such as Hansen and Prescott (2002), that accurately match industrialization, require that more technologically advanced countries industrialize at an earlier date. I find that a model that accounts for cross-country heterogeneities in population density accurately predicts the timing of industrialization in China. (JEL F43, N10, N30, O11, O14, O41) [source]


    DEMOGRAPHIC SHIFT AND PROJECTED LABOUR SHORTAGE IN CHINA

    ECONOMIC PAPERS: A JOURNAL OF APPLIED ECONOMICS AND POLICY, Issue 3 2007
    INGRID NIELSEN
    As a result of China's family planning policy of ,raising population quality and controlling population size' initiated in the late 1970s, China has accomplished a population transition from high birth rate, low mortality rate and high population growth to low birth rate, low mortality rate and low population growth within a remarkably short timeframe. Along with this population transition, however, comes a shift in population age structure, with a rapid increase in the proportion of elderly people. This paper explores the implications of China's demographic shift for labour supply and suggests policy changes to target an emerging labour shortage. [source]


    THE IMPORTANCE OF PRIVATE PROPERTY RIGHTS FOR ECONOMIC GROWTH: THE CASE OF RURAL CHINA, 1979,1987

    IAN WILLS
    This is an extended and slightly revised version of an article by Wills and Yang published in Policy, Vol. 9, No. J, Autumn 1993. The article was derived from a paper by Yang, Wang and Wills published in the China Economic Review in 1992. The idea for the empirical study, the analytical model and the procedure for quantifying changes in property rights came from Xiaokai Yang. The study illustrates his ability to apply inframarginal concepts to real problems. [source]

    GENE FLOW AND SPECIES DELIMITATION: A CASE STUDY OF TWO PINE SPECIES WITH OVERLAPPING DISTRIBUTIONS IN SOUTHEAST CHINA

    EVOLUTION, Issue 8 2010
    Yong Feng Zhou
    Species delimitation detected by molecular markers is complicated by introgression and incomplete lineage sorting between species. Recent modeling suggests that fixed genetic differences between species are highly related to rates of intraspecific gene flow. However, it remains unclear whether such differences are due to high levels of intraspecific gene flow overriding the spread of introgressed alleles or favoring rapid lineage sorting between species. In pines, chloroplast (cp) and mitochondrial (mt) DNAs are normally paternally and maternally inherited, respectively, and thus their relative rates of intraspecific gene flow are expected to be high and low, respectively. In this study, we used two pine species with overlapping geographical distributions in southeast China, P. massoniana and P. hwangshanensis, as a model system to examine the association between organelle gene flow and variation within and between species. We found that cpDNA variation across these two pine species is more species specific than mtDNA variation and almost delimits taxonomic boundaries. The shared mt/cp DNA genetic variation between species shows no bias in regard to parapatric versus allopatric species' distributions. Our results therefore support the hypothesis that high intraspecific gene flow has accelerated cpDNA lineage sorting between these two pine species. [source]


    RELATION BETWEEN VEGETATION CHANGES, CLIMATE VARIABLES AND LAND-USE POLICY IN SHAANXI PROVINCE, CHINA

    GEOGRAFISKA ANNALER SERIES A: PHYSICAL GEOGRAPHY, Issue 4 2007
    MADELENE OSTWALD
    ABSTRACT Shaanxi Province in China has been exposed to climate variability and dramatic land-use policies. The aim here is to examine vegetation changes in this area on a regional scale from 2000 to 2004 in relation to land-use changes and climate traits. The data in this assessment include remote sensing information from moderate-resolution imaging spectro-radiometer normalized difference vegetation index from 2000 to 2004, and climate data (precipitation and temperature) from 1956 to 2000. The results show an increase in vegetation production from 2000 to 2004, particularly in the north, which cannot be explained solely by climate impacts. Since the vegetation in the north is more dependent on climate variation than the other parts of Shaanxi due to more serious water limitation, the results suggest that the large-scale land-use policy implemented over the last decade, with a focus on northern Shaanxi, is possibly having an impact on the overall vegetation.

    ORIGINAL AND SECONDARY HIGH-FREQUENCY SANDSTORM ZONES IN THE LOESS PLATEAU REGION, CHINA

    GEOGRAFISKA ANNALER SERIES A: PHYSICAL GEOGRAPHY, Issue 2 2007
    JIONGXIN XU
    ABSTRACT. A study of sandstorms in the Loess Plateau and neighbouring areas is based on observations of sandstorms and precipitation. Through analysis of the relationship between the mean annual number of sandstorms and the mean annual precipitation, an original sandstorm zone and a secondary high-frequency zone of sandstorms have been defined. The latter is mainly formed as a result of human activities, such as vegetation destruction and waste-land cultivation, and not because of climatic change. The secondary sandstorm zone is located 350,500 km away from the original sandstorm zone, reflecting the fact that the sandstorm zone in the Loess Plateau area has shifted 350,500 km to the southeast, in response to human impact. Some abrupt change has been found in the area where the mean annual precipitation is 270 mm, where the original sandstorm zone ends and a secondary zone of high-frequency sandstorms begins. This transition area can be regarded as an abnormally unstable area. This study shows that destruction of the vegetation can cause changes in the environment similar to those attributed to climatic change. [source]


    USING UPLAND FOREST IN SHIMENTAI NATURE RESERVE, CHINA,

    GEOGRAPHICAL REVIEW, Issue 3 2003
    STEVE S. W. XU
    ABSTRACT. The Shimentai Nature Reserve in Yingde County, Guangdong Province, China, established recently in a subtropical upland forest area, has served for ages as an essential and customary source of livelihood for local people. Assessment of forest usage indicates heavy reliance by villagers on its diversified biotic resources. This forest dependence, associated with socioeconomic factors such as distance from village, ethnic origin, out-migration of rural youngsters, and a local tradition of conservation, is unlikely to decline in the near future. The reserve management recognizes the need to address the livelihood issues of local people and to win local support. A pragmatic adherence to provincial and higher-level policies that exclude forest-tapping activities could lead to more people-versus-park conflicts, which would dilute fundamental conservation objectives. A more enlightened and localized approach that nurtures a synergy between limited forest use and conservation while helping to develop new income sources could furnish workable alternatives.

    2. CROSSING CULTURAL BORDERS: HOW TO UNDERSTAND HISTORICAL THINKING IN CHINA AND THE WEST1

    HISTORY AND THEORY, Issue 2 2007
    JÖRN RÜSEN
    ABSTRACT Topical intercultural discourse on historical thinking is deeply determined by fundamental distinctions, mainly between the "East" and the "West." The epistemological preconditions of this discourse are normally not reflected or even criticized. this article follows Chun-Chieh Huang's attempt to give Chinese historical thinking a new voice in this intercultural discourse. It agrees with Huang's strategy of focusing the description of the peculiarity of Chinese historical thinking on fundamental criteria of historical sense-generation. Huang argues for a strict difference between the Chinese way of sense-generation in history and the Western one. against this distinction I argue that both traditions of historical thinking follow the same logic, namely that of the exemplary mode, which is known in the Western tradition by Cicero's slogan "Historia vitae magistra." Instead of claiming this mode as typical of Chinese historical thinking, I propose to clarify the difference between China and the West by looking for a modification of the same logic. Finally the question arises as to what the paradigmatic shift of historical thinking from the exemplary to the genetic mode means for the Chinese tradition Huang has presented. This shift cannot be understood as only a Western one, since it is a mode of pursuing modernity in history by a fundamental temporalization in the interpretation of the human world. [source]

    THE PEST STATUS OF BEMISIA TABACI IN CHINA AND NON-CHEMICAL CONTROL STRATEGIES,

    INSECT SCIENCE, Issue 3 2001
    REN Shun-xiang
    AbstractBemisia tabaci (Gennadius) has been considered as a serious pest in all of tropical, subtropical and temperate regions of the world. B. tabaci first recorded as early as in 1940s in China and has been reported as a pest of various crops in 22 provinces or cities. But only recently it has become a severe problem for vegetable and ornamental crops in Guangdong and Beijing. In China B. tabaci is known to transmit at least 5 plant viruses, including tomato yellow leaf curl virus (TYLCV), tomato leaf curl virus (TomLCV), squash leaf curl virus (SqLCV-C). So far, approximately 18 parasitoids, 17 predators and 1 pathogenic fungus were recorded in China. This paper presents an overview of B. tabaci as a pest and virus vector in China, with special attention given to non-chemical control strategies. [source]

    The Rise and Fall of Chinese Immigration to Canada: Newcomers from Hong Kong Special Administrative Region of China1 and Mainland China, 1980,20002

    INTERNATIONAL MIGRATION, Issue 3 2005
    Peter S. Li
    ABSTRACT An emerging perspective in the study of global diasporas stresses the effect of economic globalization and migration shifts in reshaping the population and identifying the formation of diaspora communities. This paper analyses the immigration patterns from Hong Kong and mainland China to Canada between the 1980s and 1990s, and shows that the migration shifts have been influenced by political and economic forces in Hong Kong and China, as well as changes in Canada's immigration policy. The imminent return of Hong Kong to China in 1997 and its uncertain political future in the 1990s were often cited as the main reasons for Hong Kong's large emigration in the late 1980s and early 1990s. In reality, the rising volume of Hong Kong emigration was prompted by the 1989 Tiananmen Square incident in China and its aftermath, and by the booming economy of Hong Kong in the early 1990s that created the means for many middle-class Chinese to emigrate. At the same time, Canada's expansion of the Business Immigration Program in the mid-1980s also benefited immigrant entrepreneurs from Hong Kong. In contrast, the Asian Financial Crisis of 1997 did not deter the economic growth of China. Immigration from China rose after 1989 when Canada allowed Chinese students studying in Canada to immigrate, but it was after the mid-1990s that immigration from China expanded due to Canada's greater emphasis on admitting economic immigrants and to China's growing middle class. The continuous arrival of well-educated and urban-based immigrants from China is likely to change the population composition and identity complexity of the Chinese community in Canada. LES HAUTS ET LES BAS DE L'IMMIGRATION CHINOISE AU CANADA : LES NOUVEAUX VENUS ORIGINAIRES DE LA RÉGION ADMINISTRATIVE SPÉCIALE DE HONG KONG1 ET DE LA CHINE CONTINENTALE, 1980,2000 Une perspective émergente dans l'étude des diasporas mondiales souligne l'effet de la mondialisation économique et des glissements migratoires dans le remodelage des populations et l'identification de la formation des communautés issues des diasporas. Cet ouvrage analyse les comportements migratoires en provenance de Hong Kong et de la Chine continentale en direction du Canada entre les années 80 et 90, et montre que les glissements migratoires ont été influencés par des forces politiques et économiques à l',uvre à Hong Kong et en Chine, ainsi que par des changements intervenus au niveau de la politique canadienne d'immigration. Le retour imminent de Hong Kong à la Chine en 1997 et son avenir politique incertain dans les années 90 ont souvent été cités comme les principales raisons pour l'importante émigration qui s'est produite au départ de Hong Kong à la fin des années 80 et au début des années 90. En réalité, l'ampleur croissante de l'émigration en provenance de Hong Kong a été suscitée par les événements de la place Tiananmen qui ont eu lieu en 1989 et par leurs retombées, ainsi que par l'essor économique de Hong Kong au début des années 90, ayant procuréà bon nombre de Chinois de la classe moyenne les moyens d'émigrer. Parallèlement, l'expansion du programme d'immigration commerciale mis en place par le Canada au milieu des années 80 a également profité aux entrepreneurs immigrants de Hong Kong. Par comparaison, la crise financière asiatique de 1997 n'a pas produit d'effet dissuasif sur la croissance économique de la Chine. L'immigration en provenance de Chine continentale a augmenté après 1989, lorsque le Canada a autorisé les étudiants chinois se trouvant sur son sol à immigrer légalement, mais ce n'est qu'après le milieu des années 90 que l'immigration en provenance de Chine s'est accélérée sous l'effet de la politique canadienne facilitant l'entrée au Canada des immigrants économiques et aussi de la progression de la classe moyenne en Chine. L'arrivée continue d'immigrants chinois instruits et originaires des villes est susceptible de modifier la composition de la population et la complexité identitaire de la communauté chinoise au Canada. EL AUMENTO Y CAÍDA DE LA INMIGRACIÓN CHINA AL CANADÁ: RECIÉN LLEGADOS DE LA REGIÓN ADMINISTRATIVA ESPECIAL DE HONG KONG1 Y DE CHINA, 1980,2000 En los estudios realizados sobre las diásporas en el mundo, se observa el efecto que tienen la globalización económica y los cambios migratorios en la reconfiguración de la población y en la conformación de comunidades de la diáspora. En este artículo se examinan los patrones de inmigración de Hong Kong y China al Canadá en los años ochenta y noventa, y se demuestra que los cambios en la migración resultan de fuerzas políticas y económicas en Hong Kong y China, así como de cambios en la política de inmigración del Canadá. La inminente devolución de Hong Kong a la China en 1997 y la incertidumbre sobre su futuro político, fueron consideradas como la principal razón de la numerosa inmigración de Hong Kong a finales de los años ochenta y principios de los noventa. En realidad, el creciente número de emigrantes de Hong Kong se debió al incidente en la Plaza de Tiananmen en China en 1989 y a sus consecuencias, y al auge económico de Hong Kong a principios de los años noventa, que permitió que la clase media china pudiera emigrar. Al mismo tiempo, la ampliación del Programa de Inmigración Empresarial instaurado por el Canadá a mediados de los años ochenta también atrajo a empresarios inmigrantes provenientes de Hong Kong. Por su parte, la crisis financiera asiática de 1997 no afectó el crecimiento económico en la China. La inmigración de China aumentó tras 1989, cuando el Canadá autorizó a la inmigración de los chinos que estudiaban en el Canadá, pero fue ulteriormente, a mediados de los años noventa, que la inmigración desde China se amplió debido a que el Canadá decidió aceptar a inmigrantes económicos y a la creciente clase media proveniente de China. La continua llegada de inmigrantes chinos instruidos y de zonas urbanas, probablemente afecte la composición y complejidad de la identidad de la población china en el Canadá. [source]

    KINETICS OF HYDROCARBON GAS GENERATION FROM MARINE KEROGEN AND OIL: IMPLICATIONS FOR THE ORIGIN OF NATURAL GASES IN THE HETIANHE GASFIELD, TARIM BASIN, NW CHINA

    JOURNAL OF PETROLEUM GEOLOGY, Issue 4 2007
    Yunpeng Wang
    In this paper we derive kinetic parameters for the generation of gaseous hydrocarbons (C1-5) and methane (C1) from closed-system laboratory pyrolysis of selected samples of marine kerogen and oil from the SW Tarim Basin. The activation energy distributions for the generation of both C1-5 (Ea = 59-72kcal, A = 1.0×1014 s,1) and C1 (Ea = 61-78kcal, A = 6.06×1014 s,1) hydrocarbons from the marine oil are narrower than those for the generation of these hydrocarbons from marine kerogen (Ea = 50-74kcal, A = 1.0×1014 s,1 for C1-5; and Ea = 48-72kcal, A=3.9×1013 s,1 for C1, respectively). Using these kinetic parameters, both the yields and timings of C1-5 and C1 hydrocarbons generated from Cambrian source rocks and from in-reservoir cracking of oil in Ordovician strata were predicted for selected wells along a north-south profile in the SW of the basin. Thermodynamic conditions for the cracking of oil and kerogen were modelled within the context of the geological framework. It is suggested that marine kerogen began to crack at temperatures of around 120°C (or 0.8 %Ro) and entered the gas window at 138°C (or 1.05 %Ro); whereas the marine oil began to crack at about 140 °C (or 1.1 %Ro) and entered the gas window at 158 °C (or 1.6%Ro). The main geological controls identified for gas accumulations in the Bachu Arch (Southwest Depression, SW Tarim Basin) include the remaining gas potential following Caledonian uplift; oil trapping and preservation in basal Ordovician strata; the extent of breaching of Ordovician reservoirs; and whether reservoir burial depths are sufficiently deep for oil cracking to have occurred. In the Maigaiti Slope and Southwest Depression, the timing of gas generation was later than that in the Bachu Arch, with much higher yields and generation rates, and hence better prospects for gas exploration. It appears from the gas generation kinetics that the primary source for the gases in the Hetianhe gasfield was the Southwest Depression. [source]
