Industry and Spatial Spillover Effects of R&D Expenditure in Food Manufacturing IndustryDong-Hwan An* Sang-Jun Lee**Seoul National University*, Michigan State University**Relying on a frontier production approach (e.g., Luenberger’s shortage function), this study investigated the effects of R&D expenditure on the performance of individual firms in food processing industry. Particularly, we examined the simultaneous presence of spatial and industrial R&D spillover effects associated with the externalities of R&D investment in this industry. The estimation results showed that R&D investment at both industry and regionallevel plays an important role to improve the performance of individual firms in food manufacturing industry. We also found some evidences on the existence of significant inter- and intra-industryand inter-regional spillover effects of R&D investment in this industry. 본 연구는 우리나라 식품제조업의 개별기업자료를 이용하여 개별기업의 R&D 투자의 산업 및 공간 파급효과를 분석하였다. 분석방법으로는 생산경계접근법의 하나인 자료포락분석(DEA)기법을 이용하여 개별기업의 효율성을 추정하고, 효율성의 차이를 설명하는 계량모형을 추정하는 2단계 접근법을 이용하였다. 추정결과 식품제조업의 경우 연구개발(R&D) 투자는 산업 및 지역단위에서 모두 개별기업의 생산성에 중요한 역할을 하는 것으로 나타났다. 또한 연구개발 투자는 식품제조업 내의 세부산업간 그리고 지역간에 파급효과를 가지는 것으로 추정되었다.

This paper discusses the restricted distribution of the main clause phenomena (MCP) and the movement derivation of temporal and conditional clauses in English. In English, some phenomena(so-called MCP), such as argument fronting, locative inversion, preposing around be, and VP fronting are restricted to main clauses and a subset of complement clauses. The argument / adjunct asymmetry in embedded clauses follows from the locality condition of movement. In this paper both temporal adverbial clauses and conditional clauses are analyzed as (free) relatives. In this analysis, argument fronting leads to severe intervention effects, while adjunct fronting does not. By analogy with the movement analysis of temporal clauses, this paper explores and elaborates on the proposal that conditional clauses can be derived by leftward operator movement to the left periphery of clause. This movement analysis is shown to account for the incompatibility of MCP in conditional clauses in terms of intervention effects

The purpose of this paper is to account for the syntactic distribution of English adverbs, the properties they have and the formal licensing conditions they obey. Specifically, it critically reviews some major analyses of the structural integration and licensing of English adverbs proposed within the theoretical framework of the Minimalist Program and discusses some of their potential problems. The Minimalist proposals assume that the semantic classes of adverbs, their canonical linear order and their scope properties are defined syntactically in relation to the clause structure which is conceived as a unique and universal hierarchy of functional projections with each projection having its own specific semantic interpretation. Adverbs integrate into clause structure as unique specifiers of designated functional projections and thus enter into transparent semantic relations with the head of the functional projection they occur in. As its background, this study also makes a brief survey of major issues in the syntax and semantics of English adverbs in generative grammar in general and of theoretical and empirical problems of the adjunction-based analyses proposed specifically in the GB/PPT theory.
