The Hubs Research Project is a full-length academic paper analyzing the effectiveness of "hubs", a component of the entrepreneurship ecosystem, in the advancement and growth of entrepreneurial success in a metropolitan area.
 
  
This research will primarily focused on large and mid-sized Metropolitan Statistical Areas (MSAs), as that is where the greater majority of Venture Capital funding is located.

'''Important Notice: The last update to the hubs data was done manually by Ed and is in E:\projects\MeasuringHGHTEcosystems\HubsData-RevisedSimplified.xlsx'''
  
===Primary Data Set===
 
The Hubs data set, from SDC Platinum, has been constructed in the server:
 
Data files are in 128.42.44.181/bulk/Hubs
 
All files are in 128.42.44.182/bulk/Projects/Ecosystem/Hubs
 
psql Hubs

The Hubs Research Project is a full-length academic paper analyzing the effectiveness of "hubs", a component of the entrepreneurship ecosystem, in the advancement and growth of entrepreneurial success in a metropolitan area. It focuses on cities in the United States as the primary unit of analysis.
  
The data set includes all United States Venture Capital transactions (moneytree) from the twenty-five year period of 1990 through 2015.
+
This page contains information about data used for this research project, including data sources, location of data on RDP and details on data processing.
Data has been aggregated at the portfolio company, fund, and round level. It will be analyzed at the combined MSA level. We will be looking at in terms of number of companies funded in  number of funds active, and flow of investment in a given MSA.
 
  
  
The data set has now been uploaded to the database server, named Hubs.
 
There are 4 tables:
 
*Rounds: Rounddate, coname, state, roundno, stage1, etc.
 
*CombinedRounds: Coname, rounddate, discamount, fundname
 
*Companies: LastInv, FirstInv, coname, MSA, MSACode, Address, state, datefounded, totalknownfunding, industry(major)
 
*Funds: fundname, closingdate, lastinv, firstinv, msa, msacode, avinv, nocoinv, totalknowninv, address
 
  
Used variables:
+
Information on initial data work done prior to Summer 2017 can be found at [[Hubs Summer 2016]].
  
Companies: Coname, MSACode, Industry, state
+
'''Note on joining:''' The city-state-year ID from VC data is used as the master ID for joining datasets. Each table (e.g. income, nih, nsf, sbir, compustat) is first joined with the VC data on city-state-year ID and then the resulting tables are all joined together in the final table.
MSALookupTable: MSACode, MSASuper
 
IndustryLookupTable: IndustryMajor, InduCode
 
->
 
CompanyInfo: Coname, MSASuper, InduCode, state (complete)
 
  
Funds: fundname, msacode, state

MSAPortCos: Count(CoName) As NoPortCosFunded, CoMSASuper, RoundYear
 
...
 
 
'''Notes on Creation of Primary Data Set'''
 
 
Raw tables
 
* companies (last investment, first investment, company name, MSA, MSA code, address, state, date founded, known funding, industry)
 
* funds (fund closing date, last investment, first investment, fund name, address, MSA, MSA code, Average investment, number companies invested (NoCos), known investment)
 
* rounds (round date, company name, state, round number, stage 1, stage 2, stage 3)
 
* combined rounds (company name, round date, disclosed amount, investor)
 
* msalist (changes MSAs to CMSAs— combined MSAs)
 
*industry list (changes 6 industry categories to 4— ICT, Life Sciences, Semiconductors, Other)
 
 
Process
 
*cleaned tables to eliminate duplications, undisclosed variables
 
*changed all original characters to include CMSA and Industry Codes (companyinfo3, fundinfocleanfinal, roundinfoclean)
 
*matched funds to avoid any issues with names (i.e. Fund ABC L.P./Fund ABC LP/Fund ABC)
 
*matched roundinfoclean investors to fundinfocleanfinal investors (roundinfo.txt >> cleanfundfinal.txt)
 
*join by round and company conames
 
*bridge years (1990-2016), stage, and cmsa
 
* populate data with count of companies (Deal flow) and estimated amount ($)
 
** data set in 181 hubs folder under summarycmsa.txt (38394)
 
 
Key decisions:
 
*Threw out undisclosed co through-out as no address
 
*Count is done by joining round and company
 
*Anything fund related must be disclosed fund
 
*Near and far, and total invested, and fund counts, etc., are all done using disclosed funds that match only

===Hub Candidates Data Set===
 
 
The Hubs candidate data set is a list of potential hubs found in MSAs throughout the country. Researchers are currently pulling qualitative and quantitative information from the candidate's websites, in an attempt to categorize what can be identified as a hub. This is a difficult data set to pull, as there is little to no quantitative information available for this category of institution, and is dependent on accessibility of information to the public on the internet.
 
 
Characteristics/Variables
 
*Year Founded
 
*Square footage
 
*LinkedIN self-identifiers (what the organization classifies itself on its LinkedIN profile)
 
*Activeness on Twitter (binomial)
 
*Member Directory available online (binomial)
 
*Number of conference rooms
 
*Price ($/month) for Flex desk
 
*Offers Reserved desk (binomial)
 
*Offers office space for rent (binomial)
 
*Offers community membership-- not for coworking but for community events, etc. (binomial)
 
*Number of events offered per month (estimate)
 
*Offers code academy
 
*Mission Statement/Vision (for qualitative or key-word analysis)
 
 
These characteristics/variables will be used to determine whether a candidate is or is not likely to be a Hub.
 
 
As of March 10th 2016, the list contains 125 Hub candidates.
 
 
'''Where to find''': The Hubs data set can be found in the Ecosystem>>Hubs>>dataset folder. It is not currently in the database due to a UTF8 issue
 
 
===Supplementary Data Sets===
 
'''Patent data''': to be pulled from USPTO or SDC Platinum.
 
 
'''Number of STEM Graduate Students''' (NSF) and '''University R&D Spending''' (NSF):
 
*University R&D Data found under file "NSF DATA_2004 to 2011.xlsx" in datasets folder (Ecosystem>>Hubs>>Datasets)
 
*R&D spending found at the university level for 2014 ("Stem Grad Students.xlsx) or at state level ("Science and Engineering Grad Students by State and Year 2000-2011.csv")
 
** not uploaded to server or matched yet to CMSA code, because of this discrepancy.
 
**"Stem Grad Students.xlsx" contains categorized university by MSA, can be used for all university-based projects
 
 
'''Per Capita Income''' and '''Employment Data''' (US Census Bureau):
 
*"Per Capita Personal Income by MSA 2000-2012.xlsx" in datasets folder (Ecosystem>>Hubs>>Datasets>>Data from Yael)
 
*"Wages and Salaries by MSA 2000-2012.xlsx" in datasets folder (Ecosystem>>Hubs>>datasets>>Data from Yael)
 
**not uploaded to server or matched yet to CMSA code
 
 
'''Firm Births''' (BDS)
 
*in server 181, under table name "BDS"
 
*includes birth, death, net(birth-death) and rate(death rate) for years 1990-2013 for every msa
 
*includes code for CMSA but is not aggregated by CMSA
 
** i.e. BDS statistics are still separate for all the smaller MSAs in New York's CMSA (code=1)
 
 
===Resources===
 
* Yael Hochberg and Fehder (2015), located in dropbox
 
** Use this paper as a guideline on how to conduct the analysis
 
*US Census Bureau data on employment by MSA: http://factfinder.census.gov/faces/tableservices/jsf/pages/productview.xhtml?pid=ACS_14_5YR_B23027&prodType=table
 
*USPTO utility patents by MSA: http://www.uspto.gov/web/offices/ac/ido/oeip/taf/cls_cbsa/allcbsa_gd.htm
 
*MSA level trends: http://www.metrotrends.org/data.cf
 
 
===The Target Dataset===
 
 
We will need to process the following variables:
 
*SuperMSA - combine SanFran and SanJose, New York and Newark?, NC Research triangle, others?
 
*CSV mapping msas to cmsas is in the folder (and a table in the dbase)
 
 
 
Example dataset:
 
MSA      Year      SeedVCInv      SeedEarlyVCInv      LaterVCInv    NoDeals  FundsInvested  DistinctInvestors  ....
 
----------------------------------------------------------------------------------------------------------------------------
 
1234    2001      1000000        20000000            30000000      4          7              7
 
 
 
Note that the unit of observation is MSA-Year.
 
 
Variables to be computed at the MSA level:
 
*HubActive (binary)
 
*NoHubsActive (Count)
 
*HubSqFt
 
*Other Hub Vars (build list!!!)
 
*'''SeedVCInv'''  (Seed/Start-up)
 
*'''EarlyVCInv''' (Early Stage)
 
*'''LaterStageVC''' (Later)
 
*'''OtherStageVC''' (Buyout/Acq, Other)
 
*'''NoDeals''' (done by local VCs?)
 
**'''NoDealsNear'''
 
**'''NoDealsFar'''
 
*NoPortCosFunded
 
*'''FundsInv''' (in an MSA)
 
**'''FundsInvFromNear''' (within MSA?)
 
**'''FundsInvFromFar''' (outside MSA?)
 
*DistinctInvestors (?)
 
**DistinctInvestorsNear (within MSA?)
 
**DistinctInvestorsFar (outside MSA?)
 
*PatentCount
 
*NoSTEMGrads
 
*FirmBirths (BDS data)
 
*UniRandDSpend
 
*PerCapitaIncome
 
*Employment
 
 
We need to:
 
*Check funds invested means dollars invested
 
*Categorize near and far! Is it within MSA vs. not, within adjacent MSAs, etc.?
 
 
 
There may be a second dataset that has Hub-Industry-Year (where industry is semiconductor/non-semiconductor?).
 
 
===Final Primary Data Set===

== Defining Hubs ==
 +
'''Summer 2016''' - Last year a master list of 125 "potential" hubs was used. A scorecard was developed which filtered these 125 candidate hubs to determine which of these should be included in the study sample. This method resulted in a sample size of ~ 30. The master list and the final hubs list is titled '''Hubs Data v2_'16'''. It is located here:
 +
Z:\Hubs\2017\hubs_data
 +
 +
'''Summer 2017''' - In order to obtain a more statistically significant sample of hubs, we developed 5 criteria which produce a more relaxed definition of hubs than last year. These include
 +
 +
*Availability of co-working space
 +
*Coding classes or tech events
 +
*Some focus on the tech sector (this is important as our dependent variable is VC funding)
 +
*Presence of an accelerator
 +
*Availability of mentorship for members.
 +
 +
We will review the 125 candidate hubs and select those which satisfy a subset or all of these characteristics.

Important Notice: The last update to the hubs data was done manually by Ed and is in E:\projects\MeasuringHGHTEcosystems\HubsData-RevisedSimplified.xlsx


The Hubs Research Project is a full-length academic paper analyzing the effectiveness of "hubs", a component of the entrepreneurship ecosystem, in the advancement and growth of entrepreneurial success in a metropolitan area. It focuses on cities in the United States as the primary unit of analysis.

This page contains information about data used for this research project, including data sources, location of data on RDP and details on data processing.


Information on initial data work done prior to Summer 2017 can be found at Hubs Summer 2016.

Note on joining: The city-state-year ID from VC data is used as the master ID for joining datasets. Each table (e.g. income, nih, nsf, sbir, compustat) is first joined with the VC data on city-state-year ID and then the resulting tables are all joined together in the final table.


Data by zip code

  • Population data, 2000-2016 - US Census Bureau (E:\McNair\Hubs\summer 2017)

https://www2.census.gov/programs-surveys/popest/datasets/

  • Income data, 1998-2014 - The Internal Revenue Service (E:\McNair\Hubs\summer 2017)

https://www.irs.gov/uac/about-irs

  • DCI index, to assess the economic well-being of communities

http://eig.org/dci/interactive-maps/u-s-zip-codes

Data by MSA

We have principle cities of MSAs from the census: https://www.census.gov/geographies/reference-files/time-series/demo/metro-micro/delineation-files.html

We might be able to go City -> FIPS place code -> MSA?

Cities and their FIPS codes (which don't perfectly correspond) are available from https://www.census.gov/geo/reference/codes/place.html

The Census claims to provide city to MSA here: https://www.census.gov/geo/maps-data/data/ua_rel_download.html However, there is only CBSA!

This might do it: https://www2.census.gov/geo/pdfs/maps-data/data/rel/explanation_ua_cbsa_rel_10.pdf We can maybe track city to principal city to MSA

Defining Hubs

Summer 2016 - Last year a master list of 125 "potential" hubs was used. A scorecard was developed which filtered these 125 candidate hubs to determine which of these should be included in the study sample. This method resulted in a sample size of ~ 30. The master list and the final hubs list is titled Hubs Data v2_'16. It is located here:

Z:\Hubs\2017\hubs_data

Summer 2017 - In order to obtain a more statistically significant sample of hubs, we developed 5 criteria which produce a more relaxed definition of hubs than last year. These include

  • Availability of co-working space
  • Coding classes or tech events
  • Some focus on the tech sector (this is important as our dependent variable is VC funding)
  • Presence of an accelerator
  • Availability of mentorship for members.

We will review the 125 candidate hubs and select those which satisfy a subset or all of these characteristics.
