中西部高等教育振兴计划的政策效应评估

“中西部高等教育振兴计划”等政策旨在解决制约中西部高等教育发展的突出问题,然而,目前多数相关研究仍然集中于政策文本的质性分析。研究采用双重差分法(DID)构建计量模型评估了“中西部高等教育振兴计划”的政策效应。研究发现:其一,入选“中西部高校基础能力建设工程”的省属地方高校的科研课题立项数提高了13.40%,科研成果产出提高了14.80%,科研成果获奖提高了28%。其二,随着“中西部省域高水平大学建设”政策的相继实施,中西部省域高等教育的专利授权转让数提高了22.1%,并通过科研成果转化参与到区域社会经济发展中;中西部省域高职称教师规模增量获得了5.50%的纯政策效应,充实了师资队伍的骨干力量,但青年教师却没有得到有效补充。展望未来,中西部高等教育振兴的重心应放在政策的可持续性和省域自足能力的培育上,并为青年教师的成长提供空间。

中西部四省区保险业比较研究与借鉴

搜集并分析、比较研究了山西、陕西、江西和广西四省区社会、经济、自然条件及保险业发展的相关数据,得出广西保险业在保费收入、保险深度、密度等方面与其他三省存在一定差距,主要是由于受经济社会发展相对落后,保险主体相对较少,兼业代理发展相对较慢及保险从业人员数量较少等因素的制约。基于此,宏观上应从经济社会协调发展,微观上须从保险主体、从业人员、保险产品创新及保险知识宣传普及等方面入手加以改进提高,从而确保广西保险业健康快速发展。

“以点带面”:区域高校集群发展何以振兴中西部高等教育

国家战略重心已转向以区域高校集群发展,发挥“极点”作用,“以点带面”为中西部高等教育振兴提供强力后劲。结合规模经济、范围经济与知识溢出效应的理论框架,构建一个考虑空间集聚或离散信息的计量模型,通过收集2015—2022年中西部19个省(自治区、直辖市)内82所高校的面板数据,检验了区域高校集群发展与中西部高等教育振兴的“集聚—溢出效应”。研究发现,中西部高校在一定地理范围内的空间集聚具有“点式效应”,所产生的规模经济、范围经济效应显著提高了学术活力、科研创新水平,其“示范效应”通过空间溢出效应表征出来,并能够通过空间效应β收敛机制推动中西部高等教育振兴。展望未来,中西部高等教育振兴的战略重心转向“软治理”机制,优化教学、科研、财务管理等制度环境,解放教学、科研人员“手脚”,以此留住人才,并在区域高校集群发展的空间格局演进中,充分发挥“极点”作用。

往日与今昔往日与今昔——中国西部汽车变迁史

当前,中国中西部地区正在加速推进工业化和城市化,已经成为全球最具增长潜力的汽车消费市场,汽车制造商们正加快步伐向中西部聚集。中国汽车市场目前的高速增长更多是依赖中西部市场的潜力。 几年前,广袤的西部大地还只是长安、力帆等少数几家车企的传统领地。随着我国汽车产业的快速发展,仿佛是在一夜之间,上汽、华晨、一汽-大众等相继驶入西部,中国汽车产业的西部版图从此发生了巨大变化。

经营性高速公路移交的法律风险研究

我国现行的《收费公路管理条例》规定,经营性收费公路的收费期限,按照收回投资并有合理回报的原则确定,最长不得超过25年。国家确定的中西部省、自治区、直辖市的经营性高速公路收费期限,最长不得超过30年。由于我国经营性高速公路建设始于上世纪80年代,近期陆续有一部分经营性高速公路收费期限到期。收费期限届满后,经营性高速公路如何移交、交通主管部门如何接收、移交过程中还存在什么问题,都是目前企业和政府十分关心的热点问题。

A Method for Spatial Heterogeneity Evaluation on Landscape Pattern of Farmland Shelterbelt Networks:A Case Study in Midwest of Jilin Province,China

On the basis of landscape ecology, combining the Spot 5 high resolution satellite imagery with GIS, a method evaluating the spatial heterogeneity of shelterbelts distribution at landscape scale is put forward in this paper. The distance coefficients of reasonable and existing landscape indexes of farmland shelterbelt networks were com-puted, and then through the classification of the distance coefficients, and the establishment of evaluation rules, the spatial heterogeneity of farmland shelterbelts was evaluated. The method can improve the evaluating system of previ-ous studies on shelterbelts distribution, resolve the disadvantages of lacking spatiality of overall evaluation, and make the evaluation results have more directive significance for shelterbelt management. Based on this method, spatial het-erogeneity of shelterbelt networks was evaluated in the midwest of Jilin Province, China. The results show that the re-gions with fewer shelterbelts and no closed network account for 34.7% of the total area, but only 4.9% of the area has relative reasonable pattern of shelterbelt networks. Many problems exist in the distribution pattern of shelterbelts, therefore, much attention should be paid to construct farmland shelterbelts in the study area.

Seasonal waterbird population changes in Lashihai Lake in northwest Yunnan, China

We studied the waterbird population at Lashihai Lake, Yunnan Province, China, which is a Ramsar Site(Wetland of International Importance), to determine seasonal variation in the species composition and size of the waterbird population. The study was conducted at five selected spots along Lashihai Lake at the same time each week from August 2011 to September 2013. In total, 62 waterbird species were recorded, of which 38.71%, 35.48%, 16.13%, and 9.68% were winter migrants, passage visitors, residents, and summer migrants, respectively. We found important seasonal changes in waterbird species composition and population size. Waterbird species richness was highest from September to the following April, with the total species numbers peaking in December. Total individual numbers peaked twice from late November to early December and mid-to-late February. However, waterbird species and individual numbers were comparatively lower from May to August. The change in species composition was determined by the arrival and departure dynamics of winter migrants and passage visitors. Winter migrants primarily caused the periodic changes in population size. Of concern,species and overall waterbird numbers seemed to be lower than the numbers in historical records. The decline of waterbird numbers implies that environmental changes caused by the implementation of the dam upstream of Lashihai Lake may have had adverse effects on this waterbird population. This study confirms the existence of major seasonal changes in species composition and size of the waterbird population at Lashihai Lake. Furthermore, the findings demonstrate that this wetland is of high conservation importance for waterbirds using the Central Asian–Indian and Asian–Pacific migratory routes.

Livelihood changes and evolution of upland ethnic communities driven by tourism:a case study in Guizhou Province,southwest China

As an effective livelihood approach to alleviate poverty without rural population migration, ethnic tourism has become the primary choice of economic development in ethnic areas worldwide in addition to traditional livelihood approaches. This article applies the theories of livelihood to study the community evolution driven by tourism livelihood and examine three mountainous tourism communities in different stages of tourist area life cycle. Drawing on the methods of GIS spatial analysis, semi-structured interviews and questionnaires, this article proposes a sustainable livelihood framework for ethnic tourism to explore the evolution of ethnic tourism communities by identifying changes in livelihood assets(natural, financial, social, cultural and human capitals) in the process of tourism development. The results show that the development of ethnic tourism has led to changes in the increase of building land, and the diversification of land use functions with a trend of shifting from meeting local villagers' living needs to satisfying tourists, income composition and uneven distribution of tourism income spatially. Ethnic tourism also led to the deterioration of traditional social management structure, collapse of neighboring relationship, the over- commercialization and staged authenticity of ethnic culture, as well as the gradual vanish of agricultural knowledge with a trend of increasing modern business knowledge and higher education. In addition, these changes, involving livelihood assets from natural, economic, human, social and cultural aspects are interrelated and interactive, which form new evolution characters of ethnic community. This study reveals the conflicts over livelihood approaches which have formed new vulnerabilities to impact on sustainable evolution of ethnic communities. This research provides implications for achieving the sustainable development of ethnic communities with the driving force of tourism livelihood.

Effects of Aluminum Toxicity Induced by Acid Deposition on Pine Forest Ecosystem in Longli of Guizhou Province, Southwestern China

The effects of acid deposition on pine forest ecosystems in Longli of Guizhou Province, southwestern China are studied using indoor experiments and model simulations. Indoor experiments are designed to explore the aluminum toxicity on pine seedlings, and the long-term soil acidification model （LTSAM） and a terrestrial biogeochemistry model （CENTURY） are used to simulate the influences of acid deposition on pine forest ecosystems. The indoor experiment results of aluminum toxicishow that aluminum ions in solution limit plant growth and acid deposition enhances this effect by facilitating the release of aluminum ions from the soil. Pine seedling bio- mass and root elongation decrease as the aluminum concentration increases. The results of model simulations show that the soil chemis- try varies significantly with different changes in acid deposition. When the acid deposition increases, the pH value in the soil solution decreases and the soil A13＋ concentration increases. The increased acid deposition also has negative impacts on the forest ecosystem, i.e., decreases plant biomass, net primary productivity （NPP） and net C02 uptake. As a result, the soil organic carbon （SOC） decreases be- cause of the limited supply of decomposition material. Thus acid deposition need be reduced to help protect the forest ecosystems.

Untangling the interactions among the Sustainable Development Goals in China

Understanding the interactions(synergies and trade-offs)among the Sustainable Development Goals(SDGs)is crucial for enhancing policy coherence between different sectors.However,spatial differences in the SDG interactions and their temporal variations at the sub-national scale are still critical gaps that need to be urgently filled.Here,we assess the spatial and temporal variation of the SDG interactions in China based on the systematic classification framework of SDGs.The framework groups the seventeen SDGs into three categories,namely“Essential Needs”“Objectives”,and“Governance”.Spatially,we found that the SDGs in“Essential Needs”&“Objectives”and“Essential Needs”&“Governance”generally show trade-offs in the eastern provinces of China.Synergies among all three SDG categories are observed in some central and western China provinces,which implies that these regions conform to sustainable development patterns.In addition,temporally,the synergies of the three SDG categories have shown a weakening trend in the last decade,mainly due to the regional differences in the progress of SDG7(Affordable and Clean Energy).Overall,our results identify the necessity for provinces to enhance the synergies between SDG12(Responsible Production and Consumption)and other SDGs to tackle the trade-offs between the“Essential Needs”and“Objectives”.Meanwhile,promoting the progress of SDG7 will also contribute to balanced development across provinces.

Geochemistry, geochronology, and petro-genesis of the early Paleozoic granitic plutons in the central-southern Jiangxi Province,China

This paper reports the systematic study on petrology, geochemistry, LA ICPMS zircons U-Pb dating, and in situ Hf isotope geology of the four plutons in the central-southern Jiangxi Province, an important part of the South China Block. In the outcrops, rocks are gradually changed from wall rock （slate or schist） to pluton （gneissic granite）; some residual blocks of sandy rock occur in the margin of pluton, and the foliations of residual blocks are parallel to those of both wail rock and gneissic granite. The thin-section observations show that the four plutons contain peraluminous minerals such as muscovite and sillimanite. The flattened and elongated feldspar and quartz grains are often visible in the gneissic granite, parallel to direction of lineation, suggesting that the granitic rock were subjected to a strong ductile sheafing. Geochemically, the A/CNK values from 13 granitic samples are between 1.03 and 1.37 with an average of 1.16, indicating that the granites are of strongly peraluminous plutons. The REE compositions of the 13 samples are similar, showing higher EREE contents, with enrichment in LREEs, depletion in Eu and REE patterns with relative LREE-enrichment and negligible Eu anomalies. They show enrichment in Rb, Th, U and depletion in Ba, Sr, Nb, Ti, belonging to a low Ba-Sr type of granite. Thus, the four bodies should be derived from the same magmatic source. Zircons used as U-Pb dating mostly exhibit euhedral shape and high Th/U values from 0.52 to 1.54 with an average of 1.08, suggesting that most zircons are of magmatic genesis. The zircons from four plutons yielded rather similar 206pb/238U vs. 207Tpb/235U concordia ages： 436.1±5.7 Ma for the Tangwan granite, 440.6±4 Ma for the Jiekou gneissic granite, 435.9±6.2 Ma for the Dongbao gneissic granite, and 441.9±3.1 Ma for the Jinxi K-granite, respectively, corresponding to Silurian Llandovery. Several xenocrysts yielded U-Pb ages around 700 Ma, implying that a breakup event took place during Neoproterozoic in the South China Block. In situ Lu-Hf isotopic analysis shows that all εHf（t） values of zircons are negative and have two-stage Hf model ages （TDM2） from 1.4 to 3.6 Ga, indicating that the Silurian granitic magma came from the re- cycle of Meso-Paleoproterozoic basement and even partly Archean rocks, and had not been effected by mantle magma. Re- searches on regional geology suggest that an intracontinental tectono-magmatic event took place during the early Paleozoic in the study areas, which is characterized by folding and thrusting, leading to crustal shortening and thickening, up to 20 km thickness. The high geothermal temperature from thickening crust and accumulation of producing high-heat radioactive elements gradually softened crustal rocks and caused a partial melting, forming peraluminous granitic magma. Under the post-orogenic extensional and de-pressure condition, these granitic magma rose and was emplaced in the upper crust, leading to development of S-type plutons

Dinosaur-bearing strata and K/T boundary in the Luanchuan-Tantou Basin of western Henan Province,China

The sequence stratigraphy and geochronology of the terrestrial dinosaur-bearing strata,i.e.,the Qiupa Formation,were poorly studied in the Luanchuan-Tantou Basin in western Henan,China.This study shows that these strata represent a complete succession from the Late Cretaceous to the early Paleogene,including the K/T boundary,in this area.Here we report a detailed study of the K/T boundary,especially its stratigraphic sequence,sedimentary characteristics,integrity,continuity,and geological implications.

Jurassic rocks,bivalves,and depositional environments of the source area of the Yangtze River,Qinghai Province,western China

Jurassic rocks are abundantly developed in the source area of the Yangtze River,South Qinghai,with the greatest thickness of 6311 m,including five stratigraphic units:Qoimaco Formation,Buqu Formation,Xiali Formation,Suowa Formation,and Xueshan Formation.Based on sufficient fossils of bivalves,ammonites,and brachiopods,the major part of these formations is ascribed to the Middle Jurassic Bathonian to Callovian.No diagnostic fossils have been found from the Lower Qoimaco Formation or Upper Xueshan Formation,which could possibly contain in part Bajocian and Oxfordian taxa respectively.
