关注数字化情境下的组织双元问题，同时突破传统净效应和单案例研究的局限，以及拓宽中小企业数字化转型问题研究边界，结合我国“专精特新”企业数字化转型现实背景，运用组织双元理论，从结构双元、领导双元和情境双元3个角度出发，通过理论演绎和文献梳理，基于“技术-组织-环境”（TOE）框架，从技术、组织和环境3个层面的5个前因条件对145家国家级专精特新“小巨人”企业双元能力提升组态路径进行实证分析。结果表明：（1）数字化水平、企业家精神、创新资源、政府补助和市场竞争都不是“专精特新”企业提升双元能力的必要条件，企业实现高双元能力是技术、组织和环境多层面因素协同作用的结果；（2）“专精特新”企业提升高双元能力的组态有3种（共4条关键路径）：创新资源主导型、技术与管理协同驱动型和政府支持下的自我驱动型，其中创新资源均为核心条件、具有普适作用，同时市场竞争均为非核心条件；（3）导致“专精特新”企业非高双元能力的组态有4种（共5条关键路径），均包含创新资源缺失。由此可见，我国中小企业应顺应数字化发展趋势，加大创新资源投入，多层面分析自身现实基础，选取不同的等效组态路径提升双元能力，同时发挥有为政府和有效... 相似文献

In addition to describing a new species, Cypripedium wumengense, as well
as a new variety, C. bardolphianum var. zhongdianense, nomenclatural and taxonomic
notes are made on its allies and the division to which they belong. They are ltrge]y
found in the Hengduan Mountains in southwestern China, characterized by the absence
of bract, havirg lip more or less covered with small wart-like outgrowths, and that as
the capsule matures the scape becomes much elongated. Six species of this group have
hitherto been reported, of which, however, C. ebracteatum and C. nutans are regarded
here as conspecific with C. fargesii and C. bardolphianum respectively. Thus, including
the new taxa described here, it composes five species and one variety: C. bardolphianum
W. W. Sm. et Farrer (var. bardolphianum and var. zhongdianense S. C. Chen), C. mic-
ranthum Franch., C. fargesii Franch., C. margaritaceum Franch. and C. wumengense
S. C. Chen. They are all grouped here into the same section, Sect. Trigonopedium
(Franch.) Pfitz., the oldest legitimate name of this group in the rank of section. 相似文献

Apostasioideae, a small subfamily of Orchidaceae, is largely distributed in tropical
Asia with its northern limit extending to the Ryukyu Islands and south China. The first Chinese
species of this subfamily was reported by E. D. Merrill (1927) based on a specimen collected
from Hainan (McClure 9519, AMES), which he regarded as Apostasia wallichii R. Br. As
later labelled by E. F. de Vogel, it is in fact identical with A. odorata Bl., a widespread spe-
cies also found in southern Guangdong, Guangxi and Yunnan of China. It was not until re-
cently that the true A. wallichii was collected from southwestern Yunnan bordering on Burma,
which is initially reported here. In addition, an interesting new species, A. ramifera S. C. Chen
et K. Y. Lang, is described from Hainan.
The only Chinese species of Neuwiedia has long been known as N. veratrifolia Bl. (of.
Iconographia Cormophytorum Sinicorum 5: 602, t. 8034. 1976, and Flora Hainanica 4 180, t.
1078. 1977), which, however, was considered by de Vogel (1969) to be not found in China. In
de Vogel's revision, no Chinese taxon but a variety, N. zollingeri Rchb. f. var. singapureana
(Baker) de Vogel, is cited with some doubt based on a specimen of Hainan (F. C. How 73122,
in young fruit, AMES). N. zollingeri var. singapureana is in fact quite different from N.
veratrifolia by having glandular hair, much shorter inflorescence and flattened filaments. As
recently pointed out by de Vogel and G. Barretto (in Journ. Taiwan Museum 37: 78. 1984),
the plants found in Hongkong, as well as those in Guangdong and Yunnan, possess glandular
hair and short inflorescence. They are identical with the Vietnamese species N. balansae Gagnep.,
which was reduced by de Vogel to a synonym of N. zollingeri var singapureana. E. F. de
Vogel's suggestion seems to be acceptable except the varietal rank. It is treated here as a se-
parate species, N. singapureana (Baker) Rolfe, according to its fruit and hair characters. Thus
we have altogether one species of Neuwiedia and three species of Apostasia in China, including a new species and a newly recorded one. 相似文献
